I was gonna call this cap because CPR that long after collapse has infinitesimally small odds, but I looked it up and turns out I'm wrong. CPR anyone you see down!
My understanding was always that CPR isn't meant to revive someone its meant to keep them viable for revival by people with better training/equipment.
Yeah, basically you're trying to force some circulation through the brain by manually pumping the heart - which is as much about clearing the waste buildup out of the brain as it is getting fresh oxygen to the brain, and also about preventing clots (which will later cause aneurysms when the blood starts flowing normally). Everything else is essentially expendable/repairable/replaceable.
Even the breathing part isn't very important, though the initial check to make sure the airway is clear is very important. If you're doing the chest compressions right, you'll force some airflow through the lungs anyway. The important part is getting the blood to circulate. Having stagnant blood sitting in the brain is really bad.
The current CPR procedure recommends 100-120 chest compressions of at least 2" (5cm) per minute. You are going to hurt them. You may crack their ribs. You need to compress the heart through their ribs and muscle and other tissue that's in the way. Even if you're in good physical shape, it is an exhausting thing to do. It's definitely something worth learning to do correctly - take a class if you can! You can absolutely save someone's life if their heart stops.
I did CPR training a while back, including AED use. It was fun - and sobering. The takeaway was basically: the odds of your victim surviving this is low, but any chance is better than no chance. They also drilled into us that good CPR will likely crack some ribs. Which is again preferable to, you know, being dead.
They also had us training on two mannequins. First one was the ‘nice’ dummy that’s easy to compress and teaches good form. Then they switched it out for a ‘lifelike’ dummy, which supposedly simulates the actual strength needed for good CPR. And man, that’s a workout for sure. After performing five minutes of solo CPR on that bad boy, I was about ready to need that AED myself. I’m quite a chunky individual, and even leveraging my body weight that took a bit of strength. We had a petite girl in our class who couldn’t manage it.
