Besides, if you've been trained in CPR and are waiting 2.5 minutes at a time to see if someone might take a shallow breath before you go to work, you're simply doing it wrong.
The compressions are more important than the breathing component of CPR these days for those who learned CPR back in the Pre-Xbox Era of Civilization. THe protocols have been changed. There is also some indication that performing the Heimlich on a drowned person before starting CPR helps too.
Well, maybe it's just me, but when I'm 86, and a similar event happens to me, I want that nurse to be there, and I want her to do the same thing- well except for the calling 911 part. I don't want to have my chest pounded on, and I don't want to live on a ventilator with brain damage until someone who loves me has the sense to let me go.
"God is the name by which I designate all things which cross my path violently and recklessly, all things which alter my plans and intentions, and change the course of my life, for better or for worse."
