1. If I remember well the first aid course each minute without CPR reduce the survival chance by 10%. (EDIT : See correct statement hereunder)

  2. As a first responder I saw it work once where a man crashed a motorcycle and hit a metal guard rail. His heart stopped but he was otherwise not to badly injured. After about 1 min of CPR he regained consciousness. It was a rare fluke thing. As others have responded, it is to keep your brain and tissues oxygenated until the hospital and has a 10% success rate.

  3. If you have an out of hospital cardiac arrest, the chances of you surviving to discharge from hospital are about 10%.

  4. I'm not a doctor, so idk but I heard it only works about 10 percent of the time, and i also heard about half of people brought back have some type of brain damage.

  5. It’s part of a chain. That person needs early access to CPR. They need early access to oxygen. They need early access to defibrillation. They need early access to cardiac monitoring and interventions. I’ve seen two compressions restore a heartbeat. I’ve seen three zaps restore normal rhythm. I’ve seen 20 minutes of CPR in the back of an ambulance be a total waste.

  6. Usually the EMT/Firefighter doesn't see the person "wake up". They do CPR to keep the blood flowing/heart pumping until the person eats to the hospital. My fiance is a Firefighter. He doesn't tell me about every call, but from the ones he tells me about, it's about 50/50. He's told me about people who have become conscious while they're doing CPR, but it's not that common for someone like that to see the person fully conscious and ok.

  7. It depends on the patient. Adults that are in need of CPR are more likely incapacitated by something that CPR isn't going to fix. It's usually due to a cardiovascular issue. You are just keeping them alive. Children, especially under 5, are much more likely to experience a dramatic recovery from CPR because they are more often incapacitated by choking, drowning, and other respiration-involved problems, and if blockage is cleared and breathing restarted then the results are better. All that said, I can't give you a ratio of adult to child success/survival. This is just my anecdotal experience

  8. It works frequently. If your EMT friend hasn't seen it work I question his competence and the competence of their colleagues.

  9. CPR is a form of first aid. The aim of first aid is to prevent the situation from getting worse and increase the patient's chances that they are still alive by the time they can get treated by a professional.

  10. My boyfriend is an EMT and he says that if you get to do correct CPR right away, the chance is good......however in most cases correct CPR wont be preformed for a long time before FRs get there.
