Il rebreather consentiva il mantenimento della PO2 costante a 0,7 ATA indipendentemente dalla profondità ed aveva esteso enormemente le possibilità d’intervento subacqueo dei SEAL’s incrementando i tempi di permanenza in immersione. L'uso di mezzi di trasporto a medio raggio estendeva ulteriormente le possibilità operative dei SEAL’s. Ma l’estensione dei limiti operativi comportava lunghissime soste di decompressione. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: left;"&gt;&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;
&lt;span style="font-size: 78%;"&gt;Le soste venivano calcolate attraverso le Standard Navy Air Decompression Tables. &lt;/span&gt;&lt;/div&gt;&lt;div style="font-family: Arial,Helvetica,sans-serif; margin: 0.08in 0.1in 0.19in; text-align: justify;"&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"&gt;&lt;tbody&gt;

Obiettivo: costruire un algoritmo quanto più aderente possibile alle cognizioni dell’epoca in materia di teoria cinetica dei gas ed alle reali condizioni d’impiego. Ultimato l’algoritmo iniziarono le sperimentazioni per verificare che lo stesso fosse sicuro. Uno dei primi verificatori delle tabelle decompressive (con PO2 costante) fu il Cap. Ed Thalmann, Senior Medical Officer del NEDU. Dal 1981, CAPT Thalmann supervisionò centinaia di sperimentazioni che condussero allo sviluppo delle tabelle. Terminato lo sviluppo di queste e ricevuta l’approvazione della US Navy, il modello matematico era pronto per essere trasferito in un computer da immersione. &lt;br /&gt;
Molti dei prototipi costruiti nei laboratori della US Navy si dimostrarono non affidabili e si giunse alla conclusione che occorreva commissionare all’esterno il computer con il modello elaborato dalla US Navy.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;br /&gt;

Le ricerche del CAPT Thalmann continuarono presso il Naval Medical Research Institute (NMRI). Il NMRI sviluppò un modello secondo un nuovo approccio definito “probabilistic model”. Dall’approccio Haldaniano del CAPT Thalmann si passava al modello probabilistico del NMRI. Bisognava individuare e ridurre la percentuale di rischio accettabile. &lt;br /&gt;
Tuttavia il nuovo approccio dimostrò che gli incidenti aumentavano se le condizioni dell’immersione si discostavano molto dallo standard. Nel 1990 gli studi del Decompression Computer per la US Navy furono condotti dal Naval Special Warfare Biomedical Research Program. Solo nel 1993 gli studi e le sperimentazioni produssero risultati accettabili, ma le nuove tabelle mostravano limiti anche più conservativi rispetto alle tabelle ad aria della US Navy per raggiungere quel risultato, mentre i SEAL’s avevano richiesto un algoritmo che consentisse loro decompressioni più brevi e non più lunghe... &lt;br /&gt;
Gli studi sembrarono aver raggiunto una impasse e subirono una lunga battuta d’arresto nei risultati.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;br /&gt;

Il modello calcolava la decompressione ad aria e per PO2 costante di 0,7 ATA in una miscela nitrox. Le tabelle generate da questo modello erano in qualche caso più conservative delle US Navy Standard, ma per immersioni più profonde fornivano tempi di non decompressione più ampi. La US Navy stabilì che il modello decompressivo definitivo su cui basarsi era proprio quello di Thalmann (chiamato VVAL18).&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;span style="font-size: 78%;"&gt;&lt;a href="http://3.bp.blogspot.com/_JReiH7jnVPk/TCmz5dnGUeI/AAAAAAAADhU/GCVp6woBI3w/s1600/tabella+1.jpg"&gt;&lt;img alt="" border="0" id="BLOGGER_PHOTO_ID_5488115420710195682" src="http://3.bp.blogspot.com/_JReiH7jnVPk/TCmz5dnGUeI/AAAAAAAADhU/GCVp6woBI3w/s400/tabella+1.jpg" style="cursor: pointer; display: block; height: 378px; margin: 0px auto 10px; text-align: center; width: 400px;" /&gt;&lt;/a&gt;&lt;/span&gt; &lt;br /&gt;

Sebbene il Cochran NAVY sia il computer da decompressione con l’algoritmo più aggressivo nelle immersioni che non richiedono tappe di decompressione, la sicurezza dell’operatore è sempre al primo posto. Prima di tutto il computer parte dal presupposto che il sommozzatore respiri una miscela con il contenuto più alto possibile di N2 in relazione alla profondità d’impiego; ciò non avviene nella maggior parte dei casi proprio in funzione dell’adozione di miscele e apparati di respirazione più efficienti. In secondo luogo, i SEAL’s effettuano immersioni di gruppo, ed il profilo di decompressione seguito è sempre il più penalizzante visualizzato da ogni componente il team. Le procedure d’immersione seguite sono ovviamente mirate a garantire la massima sicurezza d’impiego.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin: 0.08in 0.1in 0.19in; text-align: justify;"&gt;&lt;a href="http://3.bp.blogspot.com/_JReiH7jnVPk/TCm2q_2M-rI/AAAAAAAADh8/cyAGCmpcDeA/s1600/scheda-cochran.jpg" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"&gt;&lt;img alt="" border="0" id="BLOGGER_PHOTO_ID_5488118470737197746" src="http://3.bp.blogspot.com/_JReiH7jnVPk/TCm2q_2M-rI/AAAAAAAADh8/cyAGCmpcDeA/s1600/scheda-cochran.jpg" style="display: block; margin: 0px auto 10px; text-align: center;" /&gt;&lt;/a&gt;&lt;span style="font-size: 78%;"&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;/div&gt;&lt;div style="font-family: Arial,Helvetica,sans-serif; margin: 0.08in 0.1in 0.19in; text-align: justify;"&gt;&lt;span style="font-size: small;"&gt;Il &lt;a href="http://www.cochran.it/"&gt;Cochran NAVY&lt;/a&gt; non prevedeva l’impiego di miscele trimix o heliox. I NAVY SEALs avanzarono la richiesta di un algoritmo che tenesse conto della possibilità di utilizzare anche miscele a base di elio per specifiche missioni condotte in profondità. &lt;/span&gt; &lt;/div&gt;&lt;div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"&gt;&lt;title&gt;&lt;/title&gt;&lt;style type="text/css"&gt;

L’unità si caratterizza per la bassissima segnatura magnetica. Il computer EMC 20H Low Mu eccede le specifiche militari richieste per i teams impegnati in operazioni di sminamento. Il prodotto è stato concepito per essere impiegato nelle più disparate condizioni d’immersione con un occhio di riguardo a quelle che sono le specifiche d’impiego militare (retroilluminazione tattica, funzione scatola nera, ecc.). &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-size: 78%;"&gt;&lt;a href="http://www.gravityzero.it/"&gt;&lt;img alt="" border="0" id="BLOGGER_PHOTO_ID_5488113072394047218" src="http://4.bp.blogspot.com/_JReiH7jnVPk/TCmxwxc5jvI/AAAAAAAADgU/EkBKx6RH9qU/s400/COCHRAN_NAVY.jpg" style="cursor: pointer; display: block; height: 400px; margin: 0px auto 10px; text-align: center; width: 309px;" /&gt;&lt;/a&gt; &lt;/span&gt;&lt;span style="font-family: Courier New,monospace; font-size: small;"&gt;L’EMC-20H Low Mu è dotato del Touch Contact Programming e di alimentazione con batterie Lithium per incrementare l’affidabilità, la versatilità e la durata del ciclo di vita delle batterie. "Quando la versione civile EMC-20H è stata testate ed approvata da svariate marine militari, abbiamo ricevuto la richiesta di ridurre la segnatura magnetica dell’unità " dice Mike Cochran, Presidente e CEO della &lt;a href="http://www.cochran.it/"&gt;Cochran Undersea Technology&lt;/a&gt;. "L’EMC 20H Low Mu è la medesima versione robusta, affidabile del EMC 20H per impiego civile ma adotta una serie di materiali che rendono il computer amagnetico come richiesto dalle applicazioni militari. Questa innovazione sarà sicuramente di grande interesse per vari reparti speciali" &lt;br /&gt;
&lt;br /&gt;
L’EMC-20H Low Mu va a sostituire il NAVY VVAL 18, al quale aggiunge tutte le caratteristiche di flessibilità d’impiego e di facilità d’uso della versione civile EMC.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;br /&gt;

Se la bolla è grande, allora andrà ad occludere meccanicamente il vaso sanguigno, ma quando è piccola, più piccola del diametro del vaso sanguigno come fa  creare danni? In questo caso è il nostro organismo che la riconosce come estranea e fa sì che si inneschi una risposta infiammatoria. Questo spiega anche perché a volte, pur facendo un’immersione identica, su due sub solo uno va incontro a DCI (bolle uguali, diversa risposta infiammatoria). Il concetto dell’infiammazione spiega anche perché alcuni incidenti da decompressione si verificano dopo 24 ore dal termine dell’immersione. (TAB 1)&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Secondo Haldane (presupposto sul quale sono basate le tabelle U.S. Navy) le bolle si formavano solo se non si rispettava la velocità massima di risalita e quando si saltavano le tappe di decompressione. Su questo concetto sono basati molti computer (definiti compartimentali) basati sui programmi del professor Buhlman e chiamati Haldane modificato. Oggi si sa che non è proprio così.&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Dalle ricerche del DAN (Divers Alert Network)  emerge che il rischio individuale di incidente da decompressione è di 1 caso ogni 40000 immersioni per immersioni entro i 30 metri. Il rischio aumenta a 1 caso ogni 6600 immersioni se si fanno immersioni con stress decompressivo (immersioni ripetitive, multiday, immersioni con decompressione, immersioni oltre i 30 metri, profili inversi, ecc.).&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;E’ molto importante il riconoscimento che il nostro corpo fa delle bolle. Basta pensare al fatto che  il 58% degli incidenti da decompressione è immeritato, cioè si verifica a seguito di immersioni con profilo corretto.&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Essenziale immergersi in buone condizioni di salute per ridurre al minimo i fattori di compromissione; ne consegue l’importanza della visita di idoneità all’attività subacquea, che deve essere concepita come una visita che ci permette di andare in acqua con più sicurezza.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-left: 0.08in; margin-right: 0.08in; margin-bottom: 0in; line-height: 150%; text-align: center;"&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.gravityzero.it"&gt;&lt;img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 320px; height: 68px;" src="http://2.bp.blogspot.com/_JReiH7jnVPk/Sxuetfm3sRI/AAAAAAAAC3A/2V1Nmk-Mk_c/s320/DIVING_TEAM.jpg" alt="" id="BLOGGER_PHOTO_ID_5412093881631617298" border="0" /&gt;&lt;/a&gt;&lt;/p&gt; &lt;div class="blogger-post-footer"&gt;http://feeds.feedburner.com/CochranUnderseaTechnology&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5317195797554048345-2740956516135089258?l=divecomputer.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel="replies" type="application/atom+xml" href="http://divecomputer.blogspot.com/feeds/2740956516135089258/comments/default" title="Commenti sul post" /><link rel="replies" type="text/html" href="http://www.blogger.com/comment.g?blogID=5317195797554048345&amp;postID=2740956516135089258" title="0 Commenti" /><link rel="edit" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/2740956516135089258?v=2" /><link rel="self" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/2740956516135089258?v=2" /><link rel="alternate" type="text/html" href="http://divecomputer.blogspot.com/2009/12/qual-e-la-causa-dellincidente-da.html" title="QUAL E’ LA CAUSA DELL’INCIDENTE DA DECOMPRESSIONE? di Laura Vernotico" /><author><name>Dr Fabrizio Pirrello</name><uri>http://www.blogger.com/profile/16167003636711412358</uri><email>noreply@blogger.com</email><gd:image rel="http://schemas.google.com/g/2005#thumbnail" width="23" height="32" src="http://1.bp.blogspot.com/_JReiH7jnVPk/TQjW6QM9OcI/AAAAAAAAD60/XeDHpXx_2wk/s1600-R/posa_red.jpg" /></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://1.bp.blogspot.com/_JReiH7jnVPk/SzDanx2b8iI/AAAAAAAAC-I/VtPzn9zQF7E/s72-c/laura+vernotico.jpg" height="72" width="72" /><thr:total>0</thr:total></entry><entry gd:etag="W/&quot;CUECQXk7fyp7ImA9WxBSFk8.&quot;"><id>tag:blogger.com,1999:blog-5317195797554048345.post-6768154883273144300</id><published>2009-12-23T19:01:00.000-08:00</published><updated>2009-12-23T19:01:00.707-08:00</updated><app:edited xmlns:app="http://www.w3.org/2007/app">2009-12-23T19:01:00.707-08:00</app:edited><category scheme="http://www.blogger.com/atom/ns#" term="TECNICA" /><title>COMPUTER COCHRAN di Laura Vernotico</title><content type="html">&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_JReiH7jnVPk/SzIFCgm3W4I/AAAAAAAAC-g/vCp6yLWJ6FA/s1600-h/laura+vernotico.jpg"&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 133px; height: 106px;" src="http://2.bp.blogspot.com/_JReiH7jnVPk/SzIFCgm3W4I/AAAAAAAAC-g/vCp6yLWJ6FA/s200/laura+vernotico.jpg" alt="" id="BLOGGER_PHOTO_ID_5418398842350951298" border="0" /&gt;&lt;/a&gt;&lt;meta equiv="CONTENT-TYPE" content="text/html; charset=utf-8"&gt;&lt;title&gt;&lt;/title&gt;&lt;meta name="GENERATOR" content="OpenOffice.org 3.1  (Win32)"&gt;&lt;style type="text/css"&gt; 	&lt;!-- 		@page { margin: 2cm } 		P { margin-bottom: 0.21cm } 	--&gt; 	&lt;/style&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Abbiamo visto nel capitolo precedente quali sono le origini di questo computer. Vediamo adesso come un computer nato in ambito militare è stato diffuso in ambiente sportivo / ricreativo. Dalle origini ad oggi sono stati fatti molti studi per rendere il computer sicuro anche per chi fa immersioni in condizioni fisiche non ottimali (differenza fra subacqueo militare e non militare) e in condizioni ambientali molto variabili. Vi ricorderete come già negli anni ’90 si erano rese necessarie alcune modifiche al computer per apportare maggior sicurezza quando le condizioni dell’immersione si discostavano da quelle standard dello studio.  &lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Se osserviamo i diversi modelli di computer Cochran dalle versioni militari alle versioni civili, possiamo notare che l’algortitmo decompressivo è uguale in tutti i modelli (con dei necessari adattamenti in relazione al livello conservativo variato in funzione delle differenti esigenze d'impiego e delle differenti caratteristiche psico/fisiche degli utilizzatori). L’evoluzione dell'algoritmo impiegato nel Cochran COMMANDER NAVY  è l’EMC (Environmental &amp;amp; Microbubble Cognizant). L'acronimo  indica che il computer tiene conto delle condizioni dell’ambiente in cui si fa l’immersione (temperatura, acqua dolce o acqua salata, immersioni in altitudine), immersioni precedentemente eseguite autoadattandosi ed inoltre permette all'operatore di inserire fattori conservativi aggiuntivi per ridurre la formazione di bolle ed aumentare la sicurezza delle immersioni (un approccio preventivo). L’algoritmo prevede tappe più profonde ma più brevi per rallentare l'ascesa verso la superficie oltre ad un sofisticato sistema di controllo della velocità di risalita variabile in funzione della profondità. L’algoritmo EMC è quello che ha il range più ampio di applicazione: da immersioni brevi, a immersioni molto profonde e molto lunghe con rebreather, da immersioni ad aria ad immersioni con miscele iperossigenate o Trimix. Un fattore che riduce il rischio di incidente da decompressione è il fatto che tutta la serie Cochran parte dal presupposto che il sommozzatore respiri una miscela con il contenuto più alto possibile di azoto in relazione alla profondità d’impiego (la qual cosa non avviene nella maggior parte dei casi proprio in funzione dell’adozione di miscele e apparati di respirazione più efficienti).  &lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Si adatta perciò alle esigenze di tutti i subacquei, dai principianti ai più esigenti.  &lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Se tutti i modelli di computer Cochran utilizzano lo stesso  algoritmo decompressivo, qual è la differenza tra i diversi computer? Quello che differisce è il numero di compartimenti presi in esame: tanto maggiore è il numero di compartimenti tanto più accurata è l’analisi e quindi ridotto il rischio di un incidente. Facciamo un esempio pratico: nel modello EMC-16H i compartimenti presi in esame sono 16, nel modello EMC-20H ce ne sono quattro in più (2 più lenti e 2 più veloci) per permettere calcoli più accurati quando si usa l’elio nella miscela respiratoria.&lt;/p&gt;&lt;p style="margin-bottom: 0cm; line-height: 150%; text-align: center;"&gt;

Buhlman partendo dagli studi del prof. Haldane creatore delle tabelle U.S. Navy),  e il sistema a controllo della formazione  e sviluppo delle bolle (Varying Permeabilità Model – VPM, Reduced Bubbole Gradient Model – RGBM, Tissue Bubble Dynamics Model – TBDM)&lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Concentriamoci adesso sul modello compartimentale o meglio su un modello compartimentale modificato: il VVAL 18.&lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;A partire dagli anni Quaranta la U.S. Navy, per migliorare l’operatività degli incursori della Marina Militare degli Stati Uniti d’America,  si è impegnata nel cercare un computer affidabile (che sostituisse la decompressione calcolata attraverso tabelle U.S. Navy Standard) per calcolare la decompressione nelle immersioni multilivello. Nel  1977 i Navy SEAL’s richiesero formalmente alla U.S. Navy lo sviluppo di un computer da immersione, in quanto le immersioni militari si stavano modificando grazie all'introduzione dell’autorespiratore (rebreather) a circuito chiuso  (che consentiva il mantenimento della PO&lt;sub&gt;2&lt;/sub&gt; costante a 0,7 ATA indipendentemente dalla profondità) e all’uso in immersione di un veicolo subacqueo SDV (SEAL delivery vehicle) impiegato per operazioni subacquee estremamente lunghe che obbligavano i SEAL’s a lunghissime decompressioni. Tra la fine degli anni ’70 e l’inizio degli anni ’80 il Prof. Thalmann (Senior Medical Officer del NEDU) , terminato lo sviluppo delle tabelle e ricevuta l’approvazione della U.S. Navy iniziò a trasferire il modello matematico in un computer da immersione. Le ricerche furono affidate a  centri importanti quali il NEDU (Naval Experimental Diving Unit) e l’NMRI (Naval Medical Research Institution).&lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Il modello decompressivo preso in esame era il VVAL 18. Questo modello prendeva in considerazione diciotto tessuti con tempi di emisaturazione compresi tra 5 e 240 minuti e intervallo di campionamento ogni secondo. Secondo questo modello l’assorbimento del gas da parte dei tessuti era di tipo esponenziale mentre la sua eliminazione era di tipo lineare (nel modello compartimentale sia l’assorbimento del gas sia l’eliminazione avvenivano in maniera esponenziale). Il fatto che la desaturazione seguisse una curva lineare implicava che era accettata la formazione di un piccolo numero di bolle.  &lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Quali sono le differenze sostanziali tra le tabelle U.S. Navy standard e il modello VVAL 18?&lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Se noi facciamo un’immersione in curva di sicurezza e con tempo di fondo breve non vi è una gran differenza, se invece abbiamo lunghi tempi di fondo la “decompressione” del VVAL 18 è più permissiva per le immersioni profonde e più conservativa per le immersioni più vicine alla superficie. Se facciamo immersioni fuori curva il VVAL 18 è più conservativo e prevede tappe di decompressione più fonde. Inoltre le nuove tabelle U.S. Navy potevano essere adattate a miscele respiratorie diverse dall’aria e ad immersioni con rebreather a circuito chiuso (in quanto si trattava di tabelle decompressive  con PO&lt;sub&gt;2&lt;/sub&gt; costante).   &lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Il modello sviluppato dall’NMRI era di tipo probabilistico (individuazione e riduzione della percentuale di rischio accettabile). Gli studi rilevarono però che il rischio aumentava notevolmente se le condizioni dell’immersione si discostavano molto dalle condizioni standard. Era perciò necessario aggiungere dei fattori correttivi conservativi per aumentare la sicurezza in ogni condizione. Per fare ciò gli studi furono affidati nel 1990 al Naval Special Warfare Biomedical Research Program e nel 1993 si arrivò ad avere tabelle sicure e addirittura più conservative delle tabelle ad aria della U.S. Navy. A questo punto però era nato un nuovo problema: queste nuove tabelle prevedevano tappe di decompressione troppo lunghe per i militari. Si riprese perciò il modello Haldaniano del Capt. Thalmann che, partendo da una miscela nitrox,  calcolava la decompressione ad aria e per PO&lt;sub&gt;2&lt;/sub&gt; costante di 0,7 ATA. Le nuove tabelle , rispetto alle tabelle U.S. Navy Standard erano più permissive per immersioni più profonde. I tempi erano maturi per dar vita al primo computer che utlizzasse come modello decompressivo quello elaborato dal Prof. Thalmann. Il progetto fu affidato alla  Cochran Consulting Company ed il primo computer prese il nome di Cochran Commander. Nel 1996 il NEDU guidato da Capt. Dave Southerland iniziò i test sul computer. I test finirono nel Gennaio 1998 quando il NEDU dichiarò il  Cochran Commander NAVY pronto per i test sul campo nell’ambito dei SDV teams. Dal 2001 il computer fa parte dell’equipaggiamento standard dei SEAL’s.  &lt;/p&gt; &lt;p style="margin-bottom: 0cm; line-height: 150%;"&gt;Da allora sono stati molti studi per adattare il computer alle immersioni con miscele iperossigenate e con rebreather e soprattutto per adattare il computer alle esigenze di un utente sportivo e non militare con caratteristiche fisiche molto diverse.&lt;/p&gt;&lt;p style="margin-bottom: 0cm; line-height: 150%; text-align: center;"&gt;

Teniamo presente la formula delle pressioni parziali per gas azoto   &lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;PN2 = FN2 x P  &lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Dove:&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;PN2 = pressione parziale dell’azoto&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;FN2 = frazione dell’azoto&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;P = pressione assoluta&lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Ogni volta che il subacqueo inizia la risalita il computer ragiona su quanto azoto c’è nel compartimento che ha preso in considerazione. Se ci sono meno di 1,6 bar, dà l’ok per la risalita. Fare immersioni in curva di sicurezza significa che per ogni profondità il tempo massimo di permanenza sul fondo è tale che una volta arrivati in superficie nel nostro organismo ci sono al massimo1,6 bar di azoto. Se il computer verifica che risalendo direttamente in superficie nell’organismo ci sono più di 1,6 bar di azoto (e quindi si formano le bolle) pianifica le tappe. Come fa il computer a fare i calcoli? Per vedere se è possibile risalire almeno fino ai tre metri deve vedere se ci sono meno di 2,1 millibar di azoto (0,8 bar + 1,3 bar) se sono di più allora bisognerà fermarsi a 6 metri, se sono oltre 2,4 bar (0,8 bar + 1,6 bar) allora bisognerà fare la tappa a 9 metri. &lt;i&gt;&lt;u&gt;Questo ci dice che, tanti più tessuti prende in considerazione un computer e tanto maggiore è il numero delle campionature che fa al minuto il computer, tanto più precisa sarà l’analisi fatta e quindi l’affidabilità del computer.&lt;/u&gt;&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;I computer da immersione che adottano un algoritmo che “ragiona sulle bolle” prevedono che appena il subacqueo inizia la risalita (la pressione esterna sull’organismo si riduce e l’azoto accumulato fuoriesce dai tessuti per passare nel sangue) il 90% dell’azoto contenuto nei tessuti si diffonde nel sangue per essere eliminato con l’espirazione, mentre il 10% penetra nelle bolle che sono sempre presenti in circolo. Se il distacco dal fondo è troppo veloce, si crea una differenza di pressione tra i tessuti e l’ambiente esterno che favorisce l’ingresso di azoto nei nuclei di bolla che poi si ingrandiranno.  &lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Se vogliamo tradurre questi concetti teorici in termini pratici, possiamo affermare che il mercato ci offre diverse tipologie di computer che appoggiano un modello decompressivo piuttosto che l’altro.  &lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Non è però questo il momento per affrontare il problema relativo alla scelta del computer subacqueo, lasciamo questo argomento per un altro capitolo del nostro viaggio nel mondo della subacquea.&lt;/span&gt;&lt;/p&gt; &lt;div style="text-align: center;"&gt;&lt;p style="margin-left: 0.08in; margin-right: 0.08in; margin-bottom: 0in; line-height: 150%; text-align: center;"&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.gravityzero.it"&gt;&lt;img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 320px; height: 68px;" src="http://2.bp.blogspot.com/_JReiH7jnVPk/Sxuetfm3sRI/AAAAAAAAC3A/2V1Nmk-Mk_c/s320/DIVING_TEAM.jpg" alt="" id="BLOGGER_PHOTO_ID_5412093881631617298" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;http://feeds.feedburner.com/CochranUnderseaTechnology&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5317195797554048345-6286434653323039660?l=divecomputer.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel="replies" type="application/atom+xml" href="http://divecomputer.blogspot.com/feeds/6286434653323039660/comments/default" title="Commenti sul post" /><link rel="replies" type="text/html" href="http://www.blogger.com/comment.g?blogID=5317195797554048345&amp;postID=6286434653323039660" title="0 Commenti" /><link rel="edit" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/6286434653323039660?v=2" /><link rel="self" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/6286434653323039660?v=2" /><link rel="alternate" type="text/html" href="http://divecomputer.blogspot.com/2009/12/computer-da-immersione-con-algoritmo.html" title="COMPUTER DA IMMERSIONE CON ALGORITMO COMPARTIMENTALE O  CON SISTEMA A CONTROLLO DELLA FORMAZIONE  E SVILUPPO DELLE BOLLE di Laura Vernotico" /><author><name>Dr Fabrizio Pirrello</name><uri>http://www.blogger.com/profile/16167003636711412358</uri><email>noreply@blogger.com</email><gd:image rel="http://schemas.google.com/g/2005#thumbnail" width="23" height="32" src="http://1.bp.blogspot.com/_JReiH7jnVPk/TQjW6QM9OcI/AAAAAAAAD60/XeDHpXx_2wk/s1600-R/posa_red.jpg" /></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://2.bp.blogspot.com/_JReiH7jnVPk/SzDZKSy6zLI/AAAAAAAAC-A/TGJqSsketNc/s72-c/laura+vernotico.jpg" height="72" width="72" /><thr:total>0</thr:total></entry><entry gd:etag="W/&quot;A08HQng8cSp7ImA9WxBSFUs.&quot;"><id>tag:blogger.com,1999:blog-5317195797554048345.post-3429453315985533519</id><published>2009-12-22T04:03:00.000-08:00</published><updated>2009-12-23T04:03:53.679-08:00</updated><app:edited xmlns:app="http://www.w3.org/2007/app">2009-12-23T04:03:53.679-08:00</app:edited><category scheme="http://www.blogger.com/atom/ns#" term="TECNICA" /><title>CONCETTI DI DECOMPRESSIONE: COMPARTIMENTI O BOLLE?

La legge che è alla base di questo modello è la legge di Henry il cui enunciato è: a temperatura costante, la quantità di gas in soluzione è proporzionale alla pressione che il gas esercita sul liquido. Il volume totale di gas disciolto in un liquido (quando siamo in condizione di saturazione) dipende dal solubilità del gas, volume del liquido e la pressione con cui il gas preme su di esso.  Le bolle si formano solo se non si rispettano le tappe di decompressione e la velocità massima di ascesa. Secondo questo modello, in un’immersione in curva di sicurezza i tessuti possono sopportare il doppio dell’azoto normalmente presente in superficie (fino a 1,6  bar). Se la quantità di azoto che si libera dai tessuti in risalita è superiore al doppio del normale, allora bisogna fermarsi per una tappa di sicurezza, detta tappa di decompressione (3 metri, 6metri, 9 metri, ecc.).  &lt;/span&gt;&lt;/p&gt;    &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Ricerche sul campo ci dicono che dopo ogni immersione ci sono sempre delle bolle (più o meno numerose) e che non sempre le bolle creano problemi. Nel nostro sangue ci sono sempre microbolle con un diametro inferiore a 10 micron (quindi inferiori al diametro di un globulo rosso che misura 8 micron).  &lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Le microbolle presenti nel nostro organismo sono di due tipi:&lt;/span&gt;&lt;/p&gt; &lt;ol&gt;&lt;li&gt;&lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;microbolle a vita breve (al  massimo qualche ora); derivano dalla vorticosità del sangue nel  passaggio dalle valvole cardiache, dai movimenti muscolari e  articolari (attenzione a fare attività fisica subito prima  dell’iimersione!)&lt;/span&gt;&lt;/p&gt;  &lt;/li&gt;&lt;li&gt;&lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;microbolle a vita lunga (fino a  qualche giorno); derivano da immersioni precedenti.&lt;/span&gt;&lt;/p&gt; &lt;/li&gt;&lt;/ol&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;La pericolosità delle bolle dipende dal loro numero e dalla loro grandezza. Tradotto in termini pratici, possiamo dire che dopo immersioni senza stress decompressivo (entro i 30-40 metri, in curva di sicurezza, una sola immersione al giorno, ecc) si formano poche bolle e queste non creano problemi.  &lt;/span&gt;&lt;/p&gt;    &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Appena il subacqueo inizia la risalita (la pressione esterna sull’organismo si riduce e l’azoto accumulato fuoriesce dai tessuti per passare nel sangue) il 90% dell’azoto contenuto nei tessuti si diffonde nel sangue per essere eliminato con l’espirazione, mentre il 10% penetra nelle bolle che sono sempre presenti in circolo.   &lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Da cosa dipende la capacità o meno di entrare? Dalla resistenza che la bolla offre: tanto più piccola (compressa) è la bolla, tanto maggiore sarà la resistenza che offre all’ingresso dell’azoto. Questo è il principio della legge di Laplace. Ovviamente quando l’azoto entra nella microbolla, questa inizia ad ingrandirsi e se si ingrandisce troppo finisce per rompersi e va a creare delle bolle figlie di dimensioni inferiori. La bolla, come il gas disciolto, arriva fino al polmone. I capillari che circondano gli alveoli trattengono le bolle con un diametro maggiore di 10 micron, a questo punto l’azoto esce dalla bolla e viene eliminato con la espirazione. Se però si fanno immersioni con stress decompressivo (immersioni oltre i 30 metri, più immersioni al giorno, immersioni in più giorni consecutivi, immersioni con profilo inverso) o errori in decompressione, ecco che si formano tante  bolle e bolle grandi. A questo punto le bolle molto grosse possono danneggiare direttamente la parete del vaso, oppure il nostro organismo riconosce le bolle come estranee e le aggredisce (sviluppando una vera e propria infiammazione). Tanto più grandi sono le bolle tanto maggiore è la probabilità di avere dei problemi. La probabilità di avere un incidente da decompressione (DCI) supera il 3% quando il diametro delle bolle supera i 120 micron nelle immersioni entro i 30 metri di profondità o gli 80 micron nelle immersioni oltre i 3 metri. Immergersi spesso (più di 40 immersioni all’anno) fa bene perché così si schiacciano le microbolle che diventano più resistente all’ingresso di azoto.  &lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Un buon profilo di immersione è quello che facevano i corallari: discesa rapida (20 metri al minuto) sul fondo, distacco lento dal fondo, perché è in questo momento che si formano le prime bolle; tappe profonde (di due minuti) che servono per scaricare un po’ di azoto; negli ultimi 15 metri, risalita lenta.&lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Abbiamo visto che le bolle iniziano a formarsi nel momento del distacco dal fondo. Quando possiamo considerarle scomparse? Quattro ore dopo la fine dell’immersione. Ecco perché è importante rispettare un intervallo di superficie di almeno due ore tra un’immersione e l’altra.&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-left: 0.08in; margin-right: 0.08in; margin-bottom: 0in; line-height: 150%; text-align: center;"&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.gravityzero.it/"&gt;&lt;img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 320px; height: 68px;" src="http://2.bp.blogspot.com/_JReiH7jnVPk/Sxuetfm3sRI/AAAAAAAAC3A/2V1Nmk-Mk_c/s320/DIVING_TEAM.jpg" alt="" id="BLOGGER_PHOTO_ID_5412093881631617298" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;div style="text-align: center;"&gt; &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;http://feeds.feedburner.com/CochranUnderseaTechnology&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5317195797554048345-3429453315985533519?l=divecomputer.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel="replies" type="application/atom+xml" href="http://divecomputer.blogspot.com/feeds/3429453315985533519/comments/default" title="Commenti sul post" /><link rel="replies" type="text/html" href="http://www.blogger.com/comment.g?blogID=5317195797554048345&amp;postID=3429453315985533519" title="0 Commenti" /><link rel="edit" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/3429453315985533519?v=2" /><link rel="self" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/3429453315985533519?v=2" /><link rel="alternate" type="text/html" href="http://divecomputer.blogspot.com/2009/12/concetti-di-decompressione.html" title="CONCETTI DI DECOMPRESSIONE: COMPARTIMENTI O BOLLE? di Laura Vernotico" /><author><name>Dr Fabrizio Pirrello</name><uri>http://www.blogger.com/profile/16167003636711412358</uri><email>noreply@blogger.com</email><gd:image rel="http://schemas.google.com/g/2005#thumbnail" width="23" height="32" src="http://1.bp.blogspot.com/_JReiH7jnVPk/TQjW6QM9OcI/AAAAAAAAD60/XeDHpXx_2wk/s1600-R/posa_red.jpg" /></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="http://1.bp.blogspot.com/_JReiH7jnVPk/SzDYA9BL4sI/AAAAAAAAC94/V-T2fHhyFn8/s72-c/laura+vernotico.jpg" height="72" width="72" /><thr:total>0</thr:total></entry><entry gd:etag="W/&quot;A08DQns5eCp7ImA9WxBSFUs.&quot;"><id>tag:blogger.com,1999:blog-5317195797554048345.post-5482239162262216788</id><published>2009-12-21T04:04:00.000-08:00</published><updated>2009-12-23T04:04:33.520-08:00</updated><app:edited xmlns:app="http://www.w3.org/2007/app">2009-12-23T04:04:33.520-08:00</app:edited><category scheme="http://www.blogger.com/atom/ns#" term="TECNICA" /><title>CONCETTI DI DECOMPRESSIONE: L’ASSORBIMENTO DEL GAS INERTE di Laura Vernotico</title><content type="html">&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_JReiH7jnVPk/SzDV3vFOjsI/AAAAAAAAC9w/3KxD4TfmStI/s1600-h/laura+vernotico.jpg"&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 133px; height: 106px;" src="http://3.bp.blogspot.com/_JReiH7jnVPk/SzDV3vFOjsI/AAAAAAAAC9w/3KxD4TfmStI/s200/laura+vernotico.jpg" alt="" id="BLOGGER_PHOTO_ID_5418065505234620098" border="0" /&gt;&lt;/a&gt;&lt;span style="font-size:85%;"&gt;Prima di occuparci di come il gas inerte viene eliminato dal nostro organismo, cerchiamo di capire come fa il gas ad entrare nel nostro corpo (passaggio in soluzione del gas).  &lt;/span&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Per capire concettualmente cosa avviene ricorriamo ad un esempio.  &lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Immaginiamo di avere due contenitori che sia possibile mettere in comunicazione: uno vuoto ed uno sempre pieno. Inizialmente tra i due contenitori ci sarà una grande differenza di pressione, che andrà pian piano riducendosi man mano che il contenitore vuoto si riempie. Al ridursi della differenza di pressione si ridurrà anche la velocità con la quale si riempie il contenitore.  &lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;La legge che è alla base di questo concetto è la legge di Henry il cui enunciato è: a temperatura costante, la quantità di gas in soluzione è proporzionale alla pressione che il gas esercita sul liquido. Il volume totale di gas disciolto in un liquido (quando siamo in condizione di saturazione) dipende dal solubilità del gas, volume del liquido e la pressione con cui il gas preme su di esso.&lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;&lt;i&gt;La legge di Henry, formulata da William Henry nel 1803, regola la solubilità dei gas in un liquido. In particolare essa sostiene che:&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;&lt;i&gt;Un gas che esercita una pressione sulla superficie di un liquido, vi entra in soluzione finché avrà raggiunto in quel liquido la stessa pressione che esercita sopra di esso.&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;  &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;&lt;i&gt;Raggiunto l'equilibrio, il liquido si definisce saturo di quel gas a quella pressione. Tale stato di equilibrio permane fino a quando la pressione esterna del gas resterà inalterata, altrimenti, se essa aumenta, altro gas entrerà in soluzione; se diminuisce, il liquido si troverà in una situazione di sovrasaturazione ed il gas si libererà tornando all'esterno fino a quando le pressioni saranno nuovamente equilibrate.&lt;/i&gt;&lt;/span&gt;&lt;/p&gt;   &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Facciamo adesso un esempio pratico per arrivare ai concetti di “emisaturazione” ed “emitempo”:  &lt;/span&gt;&lt;/p&gt; &lt;ul&gt;&lt;li&gt;&lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;un contenitore contiene gas ad una  pressione costante di 100 bar&lt;/span&gt;&lt;/p&gt;  &lt;/li&gt;&lt;li&gt;&lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;un contenitore con liquido  all’interno del quale deve passare in soluzione il gas che è  contenuto nell’altro contenitore&lt;/span&gt;&lt;/p&gt; &lt;/li&gt;&lt;/ul&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;Se trascorso il primo minuto nel liquido sono passati 50 bar di gas (quindi in ogni minuto passa la metà della differenza di pressione tra il gas che deve passare e quello disciolto), all’inizio del secondo minuto il nostro contenitore di partenza contiene sempre 100 bar di gas, il contenitore pieno di liquido (inizialmente privo di gas)  ne contiene ora 50 bar. La differenza di pressione tra i due contenitori è pari a 50 bar, e visto che ne deve passare la metà ne passeranno 25 bar. Adesso il contenitore con liquido conterrà 75 bar di gas. All’inizio del terzo minuto nel contenitore col liquido passerà una quantità di gas pari alla metà di 25 bar (100 bar meno 75 bar). E così fino alla saturazione completa del contenitore col liquido, che di fatto si avvicina sempre di più a 100 senza raggiungere mai l’equilibrio: è questo il motivo per cui si parla di tempo di emisaturazione e non di tempo di saturazione (la saturazione completa non avviene mai).&lt;/span&gt;&lt;/p&gt;&lt;span style="font-size:85%;"&gt;&lt;br /&gt;Nell’esempio il contenitore con liquido rappresenta il caso di un tessuto con un tempo di emisaturazione di 1 minuto (emitempo). Vi sono tessuti più lenti con tempi di emisaturazione maggiore, per esempio 5 minuti (questo significa che il passaggio della metà della differenza di pressione tra il gas che deve passare e quello disciolto impiega 5 minuti) o più veloci, per esempio 30 sec (il passaggio della metà della differenza di pressione tra il gas che deve passare e quello disciolto impiega 30 secondi).  &lt;/span&gt; &lt;p style="margin-bottom: 0cm;"&gt;&lt;span style="font-size:85%;"&gt;I tessuti poi seguiranno lo stesso andamento temporale quando dovranno eliminare il gas.&lt;/span&gt;&lt;/p&gt;&lt;span style="font-size:85%;"&gt;&lt;br /&gt;I tessuti esaminati prendono il  nome di tessuti pilota.&lt;br /&gt;&lt;span style="font-style: italic;"&gt;Da qui l’importanza di prendere il considerazione nei calcoli della decompressione più tessuti pilota possibile per avere calcoli più precisi ed un’analisi più affidabile.&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;div style="text-align: center;"&gt;&lt;p style="margin-left: 0.08in;

verdana;"&gt;The Men&lt;br /&gt;Navy SEALS&lt;/strong&gt;&lt;/span&gt;&lt;span style="font-family: verdana;font-size:100%;" &gt; are the world's most elite band of Special Operations warriors. Named after the environments in which they operate — the SEa, Air and Land — their daring missions and courageous successes are the substance of modern legend. They are the foundation of Naval Special Warfare combat forces and stand ready, worldwide, to conduct the most difficult and dangerous Special Operations missions. Today's SEALs trace their history from the elite Frogmen, Scouts and Raiders of World War II. Training is extremely demanding, both mentally and physically, and produces the world's best Special Operations warriors&lt;br /&gt;&lt;/span&gt;&lt;span style="font-size:100%;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style="font-family: verdana;font-size:100%;" &gt;&lt;strong&gt;The Mission&lt;br /&gt;&lt;/strong&gt;&lt;/span&gt;&lt;span style="font-family: verdana;font-size:100%;" &gt;&lt;strong&gt;SEAL - Naval Special Warfare Foundation - Hawaii&lt;/strong&gt; (the "Foundation") is a nonprofit organization formed under Section 509 (a)(3) of the Internal Revenue Code of 1986 to be exempt from federal taxation as a supporting organization for the Naval Special Warfare Foundation, which is a 501(c)(3) established to raise funds in support of the families of US Navy SEALs who have died while serving our country, or who are presently serving in harm's way in trouble spots around the world. The organization is comprised of volunteers from around the country and has no employees. 100 percent of the funds raised at our fundraising events, after expenses, will go solely to improve the education, health and wellness of the spouses and children of deceased and active duty SEALs.  The Foundation’s application for exemption from federal taxation is pending. We do not foresee any problem obtaining IRS recognition as a tax exempt organization, which, when granted, will relate back to the date of formation on August 28, 2007.&lt;/span&gt;&lt;div style="font-family: verdana;"&gt;&lt;span class="Apple-style-span"  style="font-size:100%;"&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="font-family: verdana;"&gt;&lt;span class="Apple-style-span"  style="font-size:100%;"&gt;&lt;div class="sf_pagetitle"&gt;&lt;div style="display: block;"&gt;&lt;p align="center"&gt;History of SEAL Teams&lt;/p&gt;&lt;/div&gt;&lt;!-- PageTitle:End --&gt;&lt;/div&gt;&lt;!-- 6 --&gt;&lt;div class="sf_extra6"&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class="sf_subnavigation"&gt;&lt;!-- Nav:Begin --&gt;&lt;!-- Nav:End --&gt;&lt;/div&gt;&lt;!-- /sf_subnavigation --&gt;&lt;!-- 11 --&gt;&lt;div class="sf_extra11"&gt;&lt;span&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class="sf_content"&gt;&lt;!-- Content:Begin --&gt;&lt;div style="display: block;"&gt;&lt;div id="content1"&gt;&lt;div style="display: block;"&gt;&lt;div style="display: block;"&gt;&lt;p align="center"&gt;&lt;img style="width: 159px; height: 104px;" src="http://www.usnavysealfoundation.org/images/trident_free.jpg" height="123" width="159" /&gt;&lt;/p&gt;&lt;/div&gt;&lt;div style="display: block;"&gt;Today's SEAL (SEa, Air, Land) teams trace their history to the first group of volunteers selected from the Naval Construction Battalions (SeaBees) in October of 1942. These volunteers were organized into special teams called Navy Combat Demolition Units (NCDUs). The units were tasked with reconnoitering and clearing beach obstacles for troops going ashore during amphibious landings, and evolved into Combat Swimmer Reconnaissance Units.&lt;br /&gt;&lt;br /&gt;The NCDUs distinguished themselves during World War II in both the Atlantic and Pacific theaters. In 1947, the Navy organized its first underwater offensive strike units. During the Korean Conflict, these Underwater Demolition Teams (UDTs) took part in the landing at Inchon as well as other missions including demolition raids on bridges and tunnels accessible from the water. They also conducted limited minesweeping operations in harbors and rivers.&lt;br /&gt;&lt;br /&gt;During the 1960s, each branch of the armed forces formed its own counterinsurgency force. The Navy utilized UDT personnel to form separate units called SEAL Teams. January 1962 marked the commissioning of SEAL Team ONE in the Pacific Fleet and SEAL Team TWO in the Atlantic Fleet. These teams were developed to conduct unconventional warfare, counter-guerilla warfare and clandestine operations in both blue and brown water environments.&lt;br /&gt;&lt;br /&gt;Concurrently, Naval Operations Support Groups were formed to aid UDTs, SEALs, and two other unique units — Boat Support and Beach Jumpers — in administration, planning, research, and development. During the Vietnam War, UDTs performed reconnaissance missions and SEALs carried out numerous offensive operations. In 1967, the Naval Operations Support Groups were renamed Naval Special Warfare Groups (NSWGs) as involvement increased in limited conflicts and special operations.&lt;br /&gt;&lt;br /&gt;In 1983, existing UDTs were redesignated as SEAL Teams and/or SEAL Delivery Vehicle Teams and the requirement for hydrographic reconnaissance and underwater demolition became SEAL missions. The Naval Special Warfare Command was commissioned on April 16, 1987, at the Naval Amphibious Base, Coronado, California. Its mission is to prepare Naval Special Warfare forces to carry out their assigned missions and to develop special operations strategy, doctrine, and tactics.&lt;br /&gt;&lt;br /&gt;SEALs go through what is considered by some to be the toughest military training in the world. Basic Underwater Demolition/SEAL (BUD/S) training is conducted at the Naval Special Warfare Center in Coronado. Students encounter obstacles that develop and test their stamina, leadership and ability to work as a team. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/span&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;http://feeds.feedburner.com/CochranUnderseaTechnology&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5317195797554048345-3949498220538998220?l=divecomputer.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel="replies" type="application/atom+xml" href="http://divecomputer.blogspot.com/feeds/3949498220538998220/comments/default" title="Commenti sul post" /><link rel="replies" type="text/html" href="http://www.blogger.com/comment.g?blogID=5317195797554048345&amp;postID=3949498220538998220" title="0 Commenti" /><link rel="edit" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/3949498220538998220?v=2" /><link rel="self" type="application/atom+xml" href="http://www.blogger.com/feeds/5317195797554048345/posts/default/3949498220538998220?v=2" /><link rel="alternate" type="text/html" href="http://divecomputer.blogspot.com/2008/11/navy-seals-unit.html" title="NAVY SEALs UNIT by Fabrizio Pirrello" /><author><name>Dr Fabrizio Pirrello</name><uri>http://www.blogger.com/profile/16167003636711412358</uri><email>noreply@blogger.com</email><gd:image rel="http://schemas.google.com/g/2005#thumbnail" width="23" height="32" src="http://1.bp.blogspot.com/_JReiH7jnVPk/TQjW6QM9OcI/AAAAAAAAD60/XeDHpXx_2wk/s1600-R/posa_red.jpg" /></author><thr:total>0</thr:total></entry></feed>
