“**IF** you’re blowing CO2” well, it wouldn’t be.
Fortunately for our non-responsive patient, humans only extract about 1/4 of the O2 in each breath! Plenty left to help others with!
Also: CPR doesn’t require you to breathe for the patient anymore. (If you do, it’s 2breaths/30compressions.) the compressions push on the lungs a little, and the most important aspect BY FAR is to keep the blood circulating. Also avoids a decent chunk of the danger to the rescuer.
