As a subject matter expert in emergency medical services, I can provide you with an informed perspective on the success rate of CPR. The success rate of CPR, or cardiopulmonary resuscitation, can vary significantly based on several factors including the promptness of intervention, the cause of the cardiac arrest, and the quality of the CPR performed. According to the American Heart Association, when a person experiences a cardiac arrest, the chances of survival decrease by 7 to 10 percent for every minute without CPR. This highlights the critical importance of immediate action. While it's true that a high percentage of out-of-hospital cardiac arrests are fatal, CPR can indeed improve survival rates. If CPR is performed correctly and promptly, it can double or even triple a person's chance of survival. However, the actual survival rate to hospital discharge after out-of-hospital cardiac arrest varies and is reported to be around 10 to 12 percent in some developed countries with robust emergency medical systems. It's important to note that these statistics can be influenced by many variables, including the availability of automated external defibrillators (AEDs) and the response time of emergency medical services. In summary, while CPR is a critical intervention that can significantly increase a person's chance of survival following a cardiac arrest, the success rate is influenced by numerous factors and is not as high as 90 percent as sometimes reported. It's a life-saving skill that, when performed promptly and correctly, can be incredibly beneficial. read more >>

When a person has a cardiac arrest, survival depends on immediately getting CPR from someone nearby. Almost 90 percent of people who suffer out-of-hospital cardiac arrests die. CPR, especially if performed in the first few minutes of cardiac arrest, can double or triple a person's chance of survival.read more >>
