The following was posted on Compuserve Scuba Forum in the 'Technical Diving'
Section. _ I'd love to see somewone do it - hell I'd even pay!
Question:- Can someone tell me if you ever tried an emergency ascent breathing
from your bc bladder bottom mix (likely mostly inflated at depth to buoy the
doubles) and exhaling in the other bc bladder, instead of the water, to
maintain
buoyancy? We'll assume that you left your deco bottles on the anchor line and
no
diver is in sight..
That should give you the couple of fresh mix breathes needed to go to first
deco
stops. Just curious.
Answer:-
A few years ago we did some practice with re-breathing the gas that was in
the BC. You are quite right the diver is able to get several breaths, however
depending the size of the bladder time and breaths are limited to excessive
C02 build up. Never tried it during ascent, I think this would very
difficult.
Take Care
AaaaaaaaaaaaaaarrrrrrrrrrrRRRRRHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.....

Chris
