What percentage of CPR is successful?

As a medical professional with expertise in emergency medicine, I can provide you with an overview of the success rates of CPR, which stands for Cardiopulmonary Resuscitation. It's important to note that the success rate can vary significantly depending on several factors, including the setting in which CPR is performed (e.g., in-hospital vs. out-of-hospital), the cause of the cardiac arrest, and the promptness of the intervention. In general, CPR success rates are relatively low for out-of-hospital cardiac arrests, with survival to hospital discharge ranging from about 5% to 40% in some developed countries. However, when CPR is performed in a hospital setting, the success rate can be higher, with some studies suggesting rates up to 40% or more for patients who receive CPR and are successfully resuscitated. It's also crucial to consider that "success" in CPR can mean different things. Immediate success might be indicated by the return of a pulse or the patient starting to breathe on their own. Long-term success, on the other hand, involves the patient surviving to hospital discharge and having a good neurological outcome. **

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.
