What is the main aim of cardiopulmonary resuscitation (CPR)?

The primary aim of cardiopulmonary resuscitation (CPR) is to revive a person when heart or lung function has ceased. This lifesaving procedure is critical in emergencies where an individual's heart has stopped beating or they are not breathing. By performing CPR, you help maintain blood flow and oxygen supply to vital organs, which can prevent brain damage and increase the chances of survival until advanced medical help arrives.

In contrast, assisting a patient with medication, improving a patient's nutrition, and providing therapy for speech issues do not directly address immediate life-threatening situations related to cardiac or respiratory emergencies. These options focus on different aspects of patient care that are not relevant in the context of resuscitation efforts, which specifically target restoring normal heart and lung function.
