Crazy Fingers:I was told by someone that there were no recorded instances of fatal/near fatal oxtox for young, male, in shape divers below 2.0 atm PPO2. Is this true?
Usually I set my limit at 1.5 atm, but wouldn't mind knowing my statistical odds. As it is now, I know the rec limits are set for Fred & Fran Fatass, the 50 year old, smoking, half-drunk vacation diving couple. I just don't know what's realistic for people of my age and fitness group, so I have been unwilling to go past the recommendation.
Well the "Tech" limits (which includes young fit people) are 45 minutes @ 1.6. You wont find many people that will willingly exceed that. (Unless they are doing huge decos and setting regular Air Breaks etc etc)
Is susceptibility to O2 toxicity even correlated to age/fitness/BMI? I have no idea.
