Wow......Girlfriend.....wow. I hope you are feeling better...and you get back in the water soon...
There are 3 very important things that stand out from this report to me and I hope that everyone takes note of them:
1. If your buddy signals they are outta there but they are in control of themselves, follow along and render whatever assistance you can, but don't interfere unless there appears to be an immediate danger.
2. I hope this makes everyone consider keeping some sort of emergency oxygen like the RescuEAN mentioned previously in this thread.
3. If it doesn't feel right, call the dive!

Excellent reaction on your part Dave. Your fast thinking, getting her the 40%, etc most likely saved her life!
I didn't know this.
For future reference, do you know where this is listed as a Florida law? (section or statute!)
The reason I ask is that I once was told of someone at Vortex removing deco bottles left at the entrance to the cave there.

OP
I saw those bottles as I was exiting the cavern, and my mind was ticking they belonged to someone else.......
Thank you so much Dave for responding to me when I needed help...
I saw my first Pulmonary specialist today who was an assistant professor of pulmonary and critical care and he had no idea why this happened to me....He referred me to his associate who has helped to evaluate patients during chamber treatments.

I am scheduled to see his associate this Friday....

Ok, here is my (totally clueless) question. In this instance of needing positive pressure (assuming I have any way to recognize that I need it)
is there any benefit to me taaking a breath off an O2 regulator and administering it CPR-style to the victim (i.e. attempting to generate positive pressure)
or is it uselessly ineffective or just more likely to injure than to help ?
Typical CPAP pressures range from 2 to 4 inches of water pressure... so about .08 to .15 psi. Pretty gentle... and difficult to achieve manually.
But (for our docs) - would the use of oxygen and an Ambu-bag be helpful as first aid? What about the use of an Ambu-bag with air? My gut tells me "yes" but what do our docs think? And what is the most beneficial patient position? I hope I never need to know how to use it but I'll sure feel better knowing

It's a good thing he didn't go searching for our o2 bottles because they were not in the cavern. They were near the chimney so that would've been a lot of time wasted.
Oxygen and an ambu bag would be VERY useful -- oxygen is most effective if the system through which you are administering it includes a reservoir like a bag. That way, you can use a lower flow rate (oxygen lasts longer) and still have enough volume to allow the patient to inhale (a higher flow rate, but limited time). Systems without a reservoir either have to run at very high flow rates (as, for example, a demand regulator like we use on scuba does) or entrain ambient air, thus diluting the O2 (as a standard oxygen mask does).
The key to administering the highest percentage of oxygen is not diluting it. If the patient is conscious and cooperative, breathing off an O2 regulator is an EXCELLENT way to do this. If the patient is unable to hold a regulator in his mouth, a mask with a good seal and a reservoir delivery system is the best option.
I wouldn't worry about trying to deliver positive pressure in the field. It's too hard to achieve at all, and prohibitively difficult to calibrate.
The idea of someone doing mouth-to-mouth while breathing 100% is an intriguing one, though. I'm not sure I've ever heard of anyone doing that. It would undoubtedly deliver a higher percentage of O2 to the victim, but it would clearly require two person CPR to even try it.
CPR protocols, in general, are written for the lay public performing resuscitation where there are no advanced resources available. Divers are a little unusual (tech divers at least) because we may well have access to 100% O2, and some of us even carry medical mask/reservoir systems for administering it.
BTW, the position of the victim is not really important. The old "left side down" teaching is really not effective. As long as the airway is clear, the supine position is fine. Watch for vomiting and aspirating, though! If the patient begins to gag, turn him immediately onto his side, and stand ready to remove the mask and help clear the pharynx. Aspiration can turn a salvageable situation into a much worse one.
