When I first learned #CPR a few decades ago, there were a lot of caveats. But since then, studies have shown that the details aren't super important.
Nowadays, the golden rule for CPR is: Just Do It.
Not sure if they have a pulse? Start CPR anyways; you won't hurt anything.
Don't want to put your mouth on theirs? Hands-only CPR is still super effective.
Can't remember how many compressions-to-breaths, or other details? Just start doing something, anything, and it'll be a huge help.
