Read posts 7,10, 12, 13, and 15 in this thread."and the fireman teaching us says it is changing to “not expect public to give breaths”,"
Changed about four years ago IIRC. I recertify every 2-ish years as required, and around 4 years ago, maybe 5, we were being taught CPR with breathing--but told the new standards had already been written and would be making the breathing unnecessary. Which can be problematic because you have to do as you've been taught, for liability reasons, so if you are classed as "professional" or have been trained with breathing...you have to keep doing it that way. If you haven't been trained that way, then you SHOULDN'T be doing it that way.
Apparently if someone is not conscious, simply circulating the blood will oxygenate the brain "enough". Statistically? There's a 10-minute window for CPR. If started immediately, there's about a 100% chance or restarting the patient. That goes down by 10% per minute, so if you don't reach them and start CPR within five minutes, they are down to a 50% chance of being revived, with or without breathing. After ten minutes, the odds are they will need a miracle. Either way.
On the one hand, yes, I would like to know and do what is best. On the other hand, if you don't follow your certification training, you become very open to liability suits. Nice, isn't it?
The training WITH breaths is readily available, and the for scuba purposes the breaths are necessary.
