I use a seahornet first stages with oceanic alpha seconds on my deco cylinders. I can, with one hand, cover the exhaust T and hit the purge button. If you can't, change your reg or do some practice. Now YOU tell ME. What's easier in the water with a floating victim. Full-on EAR or one-handed administration of pure 02? >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. If we're blown off the wreck, separated from the boat, if there's divers hanging and the boat can't move, if there's current to swim the victim against back to the boat, then guess what? YOUR lack of meaningful activity ensures the victim dies. Karen, if your ability to understand the dynamics and variables that surround diving accidents is so limited, then stop posting. >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. Bollocks. Anyone can swim faster using a reg one-handed than while carrying out EAR. And the deco reg delivers 100 O2, not 17% plus water vapour and CO2. >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.

Damn good reason for one handed administration of 02 while you're swimming the victim. >Rather than switching to reg purging (when you're already >tired and anoxic), take breaths from the deco/nitrox bottle.

Karen, the advice you gave above, in most technical diving circumstances, will guarantee death. So spare us the trite bullshit about "placing lives at risk". If you have any information to share on techniques of applying 100% 02 via a scuba regulator, I would be happy to hear it. If all you can do is repeat "don't, it's dangerous" then your position has been noted and your advice rejected. rgrds billyw >Karen Nakamura > > > > > David, when you paramedics turn up with a bag and mask system, > > I'll be happy and relieved to stand back and hand over to you > > guys.
