if giving CPR orally, how does the CO2 from our lungs affect theirs if they need oxygen? Like, don’t they need oxygen in their lungs to go into their bloodstream to reach their brain? If were taking a deep breath of oxygen, our lungs immediately convert it to CO2, a waste product, however during oral CPR we instead breath that into the mouth and lungs of the recipient.

The newer recommendations actually say that the breaths aren’t as important as the compressions and can therefore be relatively forgotten as getting the heart started/in rhythmic the best thing. I think the breaths do help as if you’re forming a tight enough seal then it’s a direct transfer with enough oxygen in the ‘waste’ we breathe out to provide oxygen for the other person. The breaths also act as stimulatory to keep the lungs in motion
