Here’s the thing nobody tells you clearly enough: if you won’t do mouth-to-mouth, that is not a reason to stand there. Chest compressions alone can keep someone alive until help arrives.
According to the Mayo Clinic, hands-only CPR means pushing hard and fast in the center of the chest — 100 to 120 times a minute — and just doing that continuously until paramedics show up. You don’t need to put your mouth on anyone. That’s it. That’s the whole thing.
But here’s the fuller picture: a person who has stopped breathing does technically need rescue breaths to get oxygen into their lungs. That’s real. The British Red Cross explains that to give rescue breaths, you tilt the person’s head back, seal your mouth over theirs (pinching their nose closed) or over their nose, and blow in two steady breaths. If someone near you knows how to do that and is willing, great — full CPR with rescue breaths is the more complete version.
But if nobody there is going to do it? Chest compressions still matter. A lot. Keeping blood circulating is the core job, and you can do that with your hands.
So don’t let the mouth-to-mouth part paralyze you. If someone collapses and stops breathing, call 911 first, then start pushing on their chest. Hard. Fast. Don’t stop until help arrives or someone else takes over. That’s not a half-measure — that’s you actually helping.
