RE: [PSUBS-MAILIST] Escape from sub

Brent,

Depending upon the depth, we don’t really have the luxury of a controlled pressurization (a blow down is when they vent a chamber to flush out excess oxygen or other gas build ups).  The idea is to pressurize as quickly as possible so that decompression illness (DCI) due to the time for pressurization and the rapid buoyant ascent.  It would suck to make it to the surface and then be severely “bent” whether there was a surface support vessel waiting for you or not.  From personal experience, DCI even if treated successfully, messes you up for quite a while.  Your tempatic membranes will either heal or can be repaired.

Jay,  Dually noted.  I'm not privy to what conditions he was under for all his blow downs. Seals many times have classified ops they don't get to tell us about. I've always found the escape means for military subs to be horrible, when they could have proper 1 atm escape pods or subs as part of the ship, with enough space to handle all the crew.  But militaries are very well known for just doing the minimum for what it takes to kill there foe, unless forced to change inch by bloody inch. 
 
Most are subs are one or two person subs, so in many instances we should have enough time to blow down in a controlled manor. Why blow your ear drums if you don't have to.
