Nessie once bubbled...
yes, I would appreciate your sharing very much!
For me the decision wether I do rescue-breathing in the water or not depends very much on the situation, if I can get the victim to the shore/boat in an acceptable time (something definitely less than 5 minutes) I would not do it, but if it takes longer it would probably be the only option to give the victim a chance. I agree that the efficiency will probably be less in the water. But it is known that especially nearly-drown-victims quite often start breathing again after a few mouth to mouth (or mouth to mask) rescue breaths, so I would say it´s worth a try???
