Read the post again. If I can operate the reg with one hand, that leaves one hand free to extend the neck and/or seal the nose. Sealing the nose fully may not be necessary. I want to find out about this. But an arm can go under the victim's neck and wrap round so the hand can seal the nose, or that hand can hold the reg and the other hand seals the nose. Or depending on the disposition of the victim's body, just pinching the nostrils and putting pressure on nose and reg in mouth to push the head back will work. I'll figure this when I try it. > >I dout one would need to seal the exhausts completely. > >And I want to know whether it's necessary to seal the > >nostrils > > So, lets get this right - you haven't actually carried out this >procedure in the water, yet you can come on here and tell us all how to do >it? The only explanation I have given is how I can operate a reg one handed. The explanation was in answer to a specific question from Esat Attikan where he asked me to describe what my fingers were doing. Didn't you see the line about blowing the dust out of the keyboard? I've also said I'm trying to work out HOW to do this in the water. My only argument is with those who say we MUST NOT do it. > If you try it in water, you will find that the nose has to be sealed, >because with out the neck extension, and some times even with it the 02 will >follow the path of less resistance and come out via the nose This is what I was wondering about. And congratulations. This is the first piece of useful information you've posted to the list. > >No, I haven't tried it in the water. You are seeing me > >figure the process out. Then I will try it.

Stop babbling. I wrote about a) figuring the process out (understanding), b) trying it (practicing & refining the technique), and c) being prepared to use the method when necessary.

I disputed that. > > I missed nothing, apart from some plonker who came on here to tell us >all how to do some thing, Shit you're slow Grant. 1. I refuted those who said administration of partial pressure 02 from a diving regulator is impossible. 2. I answered Easat's question about how I worked a reg one handed. 3. I was open about not knowing the procedure with sealing nostrils and/or exhaust ports completely. And now you're trying to twist what I wrote and it isn't working. >that he's never even tried, in the water. Irvine >is basing what he's saying on having actually done it, you on the other hand >are basing all your assumptions on the fact that you can do it sitting in >front of your PC. The only assumption I made was about swimming being easier while using a reg one handed than while administering EAR. I haven't told anyone how to perform positive pressure ventilation. I'm still figuring it out. I have argued with those who said it is VERBOTEN.

I'll have this thing sussed and practiced in a week. That chip on your shoulder is fucking your head, Grant. rgrds billyw -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
