"What if ..?"

It happens all the time its called rescue breathing, however to perform it underwater would be an intreasting sight...

Wait, wait, wait. Is this before or after the Great White takes off your arm?

Decide that you're glad that at least you'll drown rather than get incinerated by the meteor that's about to strike.

What if you are in a team of two divers, your exit from a wreck or a cave was somehow delayed, your buddy runs out of gas, and you see that your SPG shows only enough gas, (in your estimation) to get one diver out?

What would you do?

Although it's against the very basic rule "your safety comes first", I don't think I'll leave my buddy.

What I'll do is that I'll ignore the deep stops and go ahead with my buddy to the first deco stop. We'll follow the plan as much as we can using all gases we have, although a delayed exit means a violated dive plan in terms of time spent at particular depth. Upon surfacing I'll start the normal dive accident scenario (contacting dive medical facility, breathing emergency oxygen, drinking a lot of water, and staying away from the heat).

How likely is this to happen if you don't screw the pooch in multiple other ways?

The double-fatality in Calimba is the one example I can think of, and there was so much wrong with that dive, that its a good example in how to never get into this situation...

Sheck did have an experience in _CM2M_ where he nearly died in a double fatality while obeying all the rules. They were diving thirds under the 1/3 stage + 1/3 backgas rule, but at max pen his buddy had a catastrophic gas loss problem and sheck ran out of backgas about 50 feet before the stage (his buddy had a few scrapes of gas left and went back on his own supply). That is one reason why diving stages to 1/2 and reserving backgas puts you in a better situation when you turn, since everyone should have 3x the backgas penetration gas in backgas, not just 2x. Teams of three help even more.

Thanks for the replies so far. The idea for this thread was sparked by a short anecdote by PfcAJ in the DIR forum, by the real world loss of two friends cave diving in which one had two opportunities to live, but gave his life for his friend, and by my very wise NACD cave instructor who taught me how to live through such a situation in my apprentice course.

I'll jump in later to explain the above accident and what I was taught.
