What does "CPR" stand for, and when is it used?

The abbreviation "CPR" stands for cardiopulmonary resuscitation, which is a critical lifesaving technique used in emergencies where someone's breathing or heartbeat has stopped. This often occurs in situations such as cardiac arrest, where the heart fails to pump blood effectively, or in instances of near drowning, where the individual may struggle to breathe due to water inhalation. CPR involves a combination of chest compressions and rescue breaths, helping to maintain blood circulation and oxygenation until advanced medical help arrives or the person's heart starts beating again.

The focus on CPR highlights its significance in acute medical emergencies where immediate action can mean the difference between life and death. Understanding when to apply CPR—right after recognizing signs of unconsciousness or unresponsiveness—is essential for effective intervention. This knowledge emphasizes the importance of CPR training as a fundamental skill for both rescuers and bystanders in emergency situations.
