That’s not actually true, my aunt’s late husband(He had suffered from heart disease for years) he had a massive heart attack about 15 years ago, at a soccer stadium, went into full cardiac arrest was saved..just to die a year later of another heart attack, but the point is, CPR does save lives. In fact here in L.A, there was a case of a man a few months ago, he was in the parking lot of Staples Center(About to attend the Laker game) had a massive heart attack, the fire department came and did CPR on him and he is alive today
Sure for a witnessed arrest. Michael was found unresponsive, very low survival rate. I was in EMS for 6 years and only had one save and I was off-duty at the time. Most of the time we showed we had flat-line all the way to the hospital, when we got there after a few rounds of drugs, the doctors called it.
