Which of the following best describes conditions treated with CPR?

Cardiopulmonary resuscitation (CPR) is specifically indicated for situations where the heart has stopped beating, a condition known as cardiac arrest. This is a critical emergency that leaves the individual in need of immediate intervention to restore circulation and breathing. During cardiac arrest, blood flow to vital organs ceases, which can lead to irreversible damage or death if not treated promptly.

When CPR is performed effectively, it can help maintain blood flow to the brain and other organs, giving the person the best chance of survival until advanced medical help arrives. Thus, understanding that CPR is a lifesaving technique specifically meant for cases of cardiac arrest is crucial for emergency responders.
