Regular air is 21% oxygen and almost no carbon dioxide.
Exhaled air is about 17% oxygen and about 4% carbon dioxide. Not great, but enough to get SOME oxygen into a person who isn’t breathing.
The rest of what we breathe in and out is nitrogen, which isn’t absorbed by the body.

You breathe in air, most of which is nitrogen. The oxygen content of expired air is a little lower and the carbon dioxide content a little higher than inspired air, but it isn’t that huge a difference.

There’s plenty of oxygen in exhaled air.

It has nothing to do with what we’re breathing in. It’s the process of re-inflating your lungs so your body can start breathing on its own again.

No…. the guy taking in your CO2 is converting it into oxygen …its a process that occurs in his body not yours.
