Laymen don’t do breaths anymore. You do compression and wait for the EMT’s.
They did both...no mask, no gloves...They likely killed him with the compressions....IMO
My Dad is a retired Firefighter. In the Boy Scouts as a kid, my Dad trained entire Scout Troop in CPR, as he was a Red Cross Instructor. In High School, a class mate suffered a motorcycle accident, hitting a telephone pole stump at a local park, during a race. I gave FULL CPR for over almost an hour with no help at all. I got him the hospital, he lived 3 days. Then I was in the Marine Boot Camp a week later, where they again “taught me” their version of CPR. Then I went to college and became a certified EMT, and did volunteer work for the Red Cross at sporting events.
Then I again gave full CPR at an automobile accident, and that guy also lived for 3 days.
In both cases there was massive facial bleeding.
In both cases, doctors and nurses told me that they would have let him die, if they had been on the scene.
I think I know what I am doing but thanks for your concern.
