I get training every 2 years through the Red Cross. I’d be nervous for sure because it’s a life/death situation, but the class for healthcare workers was really good and taught more than just skills, like how to manage the situation with other people at the scene. The real big thing they emphasized to us is getting the blood circulating as quickly as possible because if it remains still for too long it will clot and the victim is fucked.
They were saying that there’s a good chance you personally won’t revive the victim, but by keeping O2 going and the blood moving you’re buying time and preventing brain damage for when the paramedics arrive with better resources.
I’m disappointed that CPR isn’t a requirement to graduate High School. It’s not that hard to learn and is a really positive social good to have as many people trained as possible.
