Final answer:
It's true that early CPR can buy time in a cardiac emergency, maintaining blood flow until AED or medical professionals arrive. CPR consists of chest compressions to keep blood flowing, specifically to the brain, until the heart can resume normal operation.
Step-by-step explanation:
Yes, it is true that early CPR can buy time for the victim until an AED or emergency medical services arrive. In the event of cardiac emergencies, a device called Automated External Defibrillator (AED) is used, which delivers a large electrical shock to correct abnormal heart rhythms, a common cause of heart attacks. While an AED can correct the rhythm, during the time it takes for it to arrive or be used, early administration of CPR (Cardiopulmonary Resuscitation) can maintain the flow of blood, particularly to the brain, until the heart resumes normal beating. It is important to perform high-quality chest compressions to maintain this blood flow, and is commonly performed until professional medical assistance arrives.
