We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Cardiocerebral resuscitation (CCR) is a new approach to patients with out-of-hospital cardiac arrest that has been shown to improve rates of neurologically intact survival by 250%--300% over the approach advocated by the 2000 American Heart Association guidelines. And EMS systems can realize these improvements without having to buy a single new gadget or device.
People try to die all the time, in church, in parking lots, in supermarkets. Here's the new method to try to save them from the Grim Reaper:
That's interesting. Decades ago, when I was learned CPR, it was a given that there was no point recirculating blood if you weren't doing something to get oxygen into it. In more recent certification trainings, I was told to skip the breathing part, but they couldn't explain why. This was the first time I'd heard the idea that you've got about 10 minutes' worth of oxygen in the blood. This does seem to suggest that there's not much point to the process unless you think EMS is going to show up within 10 minutes. The compressions are a lot faster now, too.
Realistically, this doesn't save people all that often. Just often enough that it's worth trying.
Speaking as an EMT (Intermediate - Cardiac Tech) since the days of "bag and drag" EMS these standards change constantly - they can never make up their minds one way or the other as to the proper way to perform manual CPR. Living in a rural area, this technique would be hard to properly utilize because it can take ten minutes to get volunteers to the ambulance to roll on a call. Even First Responders can't get to a cardiac arrest in ten minutes.
CPR works in urban areas much better than rural. Over the years, without looking at run sheets, my service has done over three hundred cardiac arrests with one save. Compare that to the next town over where the hospital is located and the police act as First Responders, the rate is much higher - almost 30% "save rate". Their average run times from call initiation to ER is eleven minutes - ours is close to 30 and in some locations can take as long as 45.
Which is not to say that you shouldn't try. You have to at least try - there is always that chance that a life can be saved.
