| Re: scr bailout from mccr What you need to do is practice while you have working displays and document what happens. The number of breaths available to a diver is dependent on many things, diluent O2 %, metabolism of diver, depth, volume of entire loop, how much you drag in when you do hit the dil for fresh gas. Of course it will change with ascending but you dont want too many different variables to remember. 5 breaths and exhale one in SCR to 20fsw/6M and flush with O2 is a good strategy, unless you have seriously hypoxic diluent, but then, you will have deco obligations and should be on a full OC bailout plan then anyway. I teach SCR for a horizontal swim, then OC or open loop bailout to the surface with safety stop and O2 flush (if you are still on the loop) at 20fsw. No worries on the ascent that way.
