Would you do that?

If in a public situation and someone, a total stranger, is not breathing, it's a car accident, drowning, whatever, would you, no barrier device is availabe, do mouth to mouth? I have not been in thiis situation but I don't think I would.
No, but I would do chest compressions like nobody's business. If done correctly, it's all that's needed.I keep a one-way valve for mouth-to-mouth in my car.

I have a CPR mask in my car.But without it I would do chest compressions no mouth to mouth. Current guidelines say mouth to mouth isn't even needed.

Mouth to mouth would hurt the pulse less victim due to the interruptions and subsequent drop in coronary perfusion that occur while not performing compressions because of trying to ventilate the patient

NO...no mouth to mouth on strangers. I carry a one way mask in the car.It is the compressions that count

Nope. If I didn't have a one way in the car I'd do compressions only.

I'd instruct their family or someone else that this person needs CPR and then they can choose to or not to do anything. I'd call emergency, but my health and time playing candycrush is valuable.

Well, since I've already beaten all the available levels, I'd certainly have no problem attempting to save a life.

As others said, I wouldn't only because it's not necessary. If it were, and I thought it could save the persons life, I would do it.

I have done it once. No mask.

Thanks for all your replies....but the situation is that the person is not breathing but DOES have a heart rate, a pulse, then what? You have no barrier device and you don't want to contract a disease.

I would do it nyways with no mask

A long time ago I did it in the heat of the moment. Was in the grocery store in uniform (whites so very obviously a nurse) and a man comes running up to me..."Are you a nurse"? "Yes". "A woman needs help". I'm led to a woman in complete arrest. Another nurse on the scene comes along and conveniently takes the job of compressions and orders me to do respirations. (She was Army and I was Air Force...ha, ha.) I knew it was wrong to do respirations w/o a mask but when you're in the thick of it and there's a crowd forming and you want to help the person it's hard to say, "Oh, no. I can't help here. I don't have a mask." This was 15 yrs ago before the guidelines/teaching changed regarding respirations. The person was very young and had newborn twins w/ her so you really wanted to help her. There were no secretions, thank goodness, or I might have taken pause. I was freaked out afterward and went to the Public Health office on base to report an exposure. They didn't take the risk too seriously but drew blood for a few months to appease me. I didn't contract anything, thankfully. Tried to avoid wearing my whites out in public much after that.
