Having once again waded through the usual enough gas for bailout debate i was wondering if anyone knew the answer to my $10,000 question.
My hypothesis on bailout safety is bailout early.
So if my SAC hit 25-30 I bailout as a first response and ask questions latter.
The use of a BOV plummed to a large off board tank is suposed to make this a simple no brainer.
The question is: Will my SAC stabilize and drop immediately i remove the source of the C02 or will my SAC continue to rise after i have bailed out.
The sub question is: having bailed to OC what is a reasonable time frame for the increased breathing rate to subside.

Hi Mark,
Sorry to reply with a question but, wouldn't this SAC recovery time depend on the length/amount of CO2 exposure? I would imagine it would but have no clue.
Thank you for asking these questions because I've been wondering the same thing since JDicediver posted his experience. It's worrisome thinking that the BO we carry may just not be enough folowing a CO2 hit if deep enough.
Another related question would be:
Does the reducing PO2 while ascending on OCBO delay the breathing rate recovery? In other words, do we recover from CO2 poisoning faster in a rich O2 environment (like EAN36 at 30m for instance) than say by breathing surface air? I sure wouldn't hang around 30m on OC to find out but would be interesting nevertheless.
