Hey how about this: How many breaths would you have to take of air at 30ft from your OC bail out, before making an uncontrolled assent to the surface to not pass out?
Personally I would chill out for a while at depth on OC and try to figure out what just happend.
Not many. One full breath, from a fully expired lung would be enough, but the more the merrier.
