Bill - With all due respect, do you even bother to read the arguments of those you are refuting? Or are you simply just hopping up and down? I believe in the scenario we've all been talking about, we're on dry land or the boat. If you're truly able to explain how you (one person) floating in the water can use your demand regulator's purge valve to inflate your buddy, I'd like to hear that. Even two of you floating in the open water are not going to be able to effectively purge the reg; cover the exhaust; tilt the victim's head, and gauge effective inflations. You're better off heading for the boat/shore at double-speed. You can't really swim at any speed if you're using a reg. You can still swim slowly doing EAR on a victim. Retake your rescue course if you forgot how. My suggestion was that (on the shore/boat) in lieu of better equipment (a proper O2 system); doing EAR using donor breaths inhaled from the O2 reg (so that the victim is receiving about 96% O2) is much better and much safer than the crazy regulator method. People mentioned that they're worried of tiring using EAR/CPR. This is a common phenomena, even a strong person has trouble keeping it up for more than 15 minutes. Rather than switching to reg purging (when you're already tired and anoxic), take breaths from the deco/nitrox bottle. Ask a passerby to switch for you. If you've done CPR for 30 minutes and no one has stopped to say 'hello' and called for an ambulance and your patient is still not breathing, well..... things don't look good. I think every rescue diver wishes that they could use their deco bottles and demand regs as effective resuscitating devices. The simple fact is that they are extremely hazardous. Even a trained paramedic would shy away from this setup; and it's not something you would recommend to untrained personnel. To suggest otherwise is placing lives at risk.
