Jeez. It's going around. Dunno if you saw the entry on my or harpers log a couple weeks ago. Seems like people want to be directed in that situation especially if not prepared. Glad your guy was ok. Do you have cpr certification?
Yikes! Can't believe anyone would wonder whether it's worth calling EMS. Glad you were there to help.
I saw your note. That sounded very scary. It is a totally different situation when you are on city streets and an ambulance can reach you in <5 minutes. It sounds like you and Harper did everything you could, but survival is a huge challenge when the paramedics cannot get there fast.
It has been a while since I last was trained in CPR, maybe 2-3 years now. I'm due for a refresher. I was a lifeguard in the 90s, and trained quite a bit then, so the old style of CPR is etched in my memory. I have a hard time remembering the new, simpler methods. Regardless, the most important thing you can do is call EMS.
In my opinion, the biggest improvement in CPR since the 90s is not the technique changes but the ubiquitous access to AEDs that can be operated by almost anyone. At the time, I worked at a large community center and we did not have one, but now they are everywhere. Hopefully they are soon cheap enough to have in our homes. I'd buy one if they cost $100-200.
