Cardiac Arrest Survival Rates
Some new data on CPR has been released by Zoll Medical. When a cardiac arrest occurs, only half of victims will need a shock. The other half require high-quality cardiopulmonary resuscitation (CPR). A general figure is that for every 1 minute delay in the AED arriving the persons chance of survival drops by 10%. This figure is based on no one doing CPR.
If effective CPR is delivered then the survival drops by just 3-4% per minute. To clarify these figures it assumes that the person has 100% chance of survival at point of sudden cardiac arrest. This is even more evidence that effective and prompt CPR is vital for the patients chance of survival as well as effective training will teach these skills.
