I honestly need to learn. I have had to preform CPR on someone in need before until paramedics showed up and the 911 operator walked me through it and coached me through the entire process (faster or slower) Whatever I did worked and saved them til help came. I really should take the time to learn proper cpr after that, this is a good reminder!
Am I technically trained in both? Yes. Would I actually know what to do if the time came? Probably not.
Chest compressions is better than nothing. If you don’t feel comfortable doing mouth to mouth on a stranger, you can do chest compressions to circulate oxygen in the body until help arrives
