Missouri Valley First Aid Practice Test

Performing CPR, or cardiopulmonary resuscitation, is primarily aimed at restoring breath and circulation in an individual who has experienced cardiac arrest or respiratory failure. During cardiac arrest, the heart stops pumping blood effectively, which leads to a lack of oxygen reaching vital organs. CPR combines chest compressions and rescue breaths to maintain blood flow to the brain and other essential organs until emergency medical services arrive or the person can be resuscitated.

The technique effectively helps circulate blood, supplying oxygen to the body and prolonging the opportunity for successful defibrillation and other advanced care measures. This restoration of breathing and circulation is critical, as it can significantly improve the chances of survival and recovery for the patient.
