All accurate but you missed the real step 1, which is arguably the most important - Check for danger. It was drilled into us repeatedly in our course because it's extremely obvious but always easy to forget during a situation.

Our first aid teacher told us a lovely story of a child on his bike who got zapped by a downed power line. The next two family members trying to help him also died because they just rushed in. Not a great day for them.

In other situations, something as simple as pulling the park brake in a traffic accident can save a world of problems. Regardless, don't even get close enough to physically check them if you aren't sure it's safe.

There are certainly special considerations, but in the vast majority of situations where CPR is necessary, there is no external hazard to worry about, it's just Uncle Jim's diet and lifestyle catching up with him.

Often it's obvious, and checking takes no more than a second or two. It's just important that you do it.

Even if you find Uncle Jim on the floor at home, don't run in assuming a heart problem because maybe he tripped on some water and you'll do the same :) But if he starts choking right in front of you, go to town.

I don't disagree with you, but as someone who walks into a _lot_ of emergency scenes, it's really rare for there to be a hazard to worry about. Is it a thing you should consider? Sure. In reality it doesn't come up often enough to warrant "top billing" in a high level overview of how to do chest compressions.

In any emergency scene, the first thing to do is check for traffic to prevent the victim or yourself from getting run over (sometimes merely because you need to cross the street: while running to provide help in an emergency situation, you're likely to forget looking both ways).

If any one of those emergency scenes was outdoors and you didn't think of this, you're doing it wrong. And even if you've always remembered to do this yourself, it's essential that you explain it to others so they will remember it as the first thing to do.

Step 0 is the really high-yield tip here because it applies in so many emergencies. The natural shout of "someone call 911" is so often less effective: even if folks aren't halted by outright shock or confusion, their disorganization and/or assumption that somebody else will do it introduces miscommunications and delay. Nearly everyone takes to direct, simple instructions much better and faster.
