I have multiple real world saves. None are from CPR. Chest seals, wound packing hemostatic gauze, and Narcan are the majority of mine.
I even have one Heimlich save.
Nonetheless, CPR is a valuable tool for me. I keep my certification up to date and carry trauma gear pretty much everywhere. Stop the Bleed is something I wish more people would take and I teach several classes each year, typically free of charge.
I did have one CPR attempt on a gunshot victim where I took over for a bystander who was performing ineffective chest compressions. When paramedics arrived, they took over and later told me that my compressions were correctly administered.
It’s rewarding to save people. After your first one, you want to keep gear on you and keep certs up.
