Rod, That's easy to say as we sit in our warm houses with our families safe. If you were in that position, perhaps what you should do and what you would do are two different things. Would the extra 10-15 minutes it took to get to the surface and get back down put him or her to far in to the brain dead zone? What would your support on the surface be? A bunch of floundering idiots or someone waiting there with an extra rig to put on your back? Question: We all know that different people are affected by o2 tox at different depths and some people can build up a tolerance, and then I would suspect there is the odd one out there that would not be affected at all. 95%+ of the people would be commiting certain suicide making the hop to 140, however, WHAT PERCENTAGE WOULD YOU SAY YOU HAD OF MAKING IT TO THE BOTTOM recovering your mate, and blasting back to the surface to possibly get him or her recesitated and getting both of you into the chamber. Granted the odds are stacked way against you. Would you take the chance of dying if there was a slim chance your mates life would be saved. By the way we both know that this really did happen to some one just reciently. I personally feel that there are a few people worth dying for on this planet. My wife and kid are two of them. >You have to go to the boat and get fresh air to dive.
