Yes in fact I teach it and do it regularly. Out of hospital cardiac arrest survival rates are atrocious even when the person performing CPR is properly trained, let alone a panicked person trying to look up instructions on YouTube.

And I’m 100% not saying that a person shouldn’t attempt to do CPR in this scenario, just saying that any realistic scenario where the compressor is trying to look up instructions in real time is bound to fail. That’s why I volunteer my time teaching community members how to do it properly, even if it’s hands-only CPR (eg no rescue breaths)

Not defending YouTube here, but CPR is so time sensitive that if they were looking up instructions, she was a goner anyway.
