When is CPR used?

A: CPR is used when a person does not have a pulse or a blood pressure and are not responsive. CPR is also used when a person is in cardiac arrest?

Right.

That's correct! CPR, which stands for Cardiopulmonary Resuscitation, is a life-saving technique used when someone is in cardiac arrest. It is performed when a person does not have a pulse, is not breathing, or is not responsive. The purpose of CPR is to manually pump the blood and provide artificial ventilation to keep oxygenated blood flowing to the vital organs until professional medical help arrives. By learning CPR and performing it promptly, bystanders can greatly increase the chances of survival for someone experiencing cardiac arrest.
