Depending on the depth that you have to flood the sub and make a free
accent to the surface, it really depends on how fast you need to equalize
to try and get to the surface before exceeding the nitrogen uptake limits
for getting bent on course. Only the air cavity's are affected in a rapid
pressurization I believe but my sub has a rated working depth of 350' and
as I remember from the old navy tables, you only have about 5 minutes at
165' before you have to make a stop at 10' so due to that fact, I would
have to flood the sub as fast as I can to minimize the nitrogen uptake to
make it to the surface before getting bent and the negatives to that are
that most people can't clear their ears that fast so you are looking at
possibly blowing your ear drums which in turn is really painful and screws
up you equilibrium which is going to hamper your safe accent to the surface
in a timely manner. I am going to have mixed gas in my bailouts to buy me
time for getting to the surface and keeping the nitrogen uptake as minimal
as possible.
