Answer 1

It doesn’t. CPR classes are now teaching “compressions only” cpr that does not include mouth to mouth. This not only lessens the chance of spreading disease via bodily fluid contact, but also the exhaling would include higher than normal amounts of CO2 due to the high stress of the situation
