What is the immediate effect of CPR?

• A. Doubles/triples survival after cardiac arrest.
• B. Prevents any brain damage.
• C. Cures the underlying heart disease.
• D. Immediately restores full cardiac function.

Answer: (A)

The main idea is that CPR’s immediate effect is to keep blood flowing to the brain and other vital organs during a cardiac arrest. By performing chest compressions and rescue breaths, you maintain perfusion long enough for the heart to regain activity or for advanced care to take over, which significantly increases the chance of survival with good neurological outcome. Studies show that when CPR is started promptly by bystanders, survival rates can double or triple compared with no CPR. The other statements aren’t correct because CPR does not prevent brain damage completely, it does not cure the underlying heart disease, and it does not instantly restore full cardiac function—the heart often needs additional treatment to restart normal rhythm.
