How is effective CPR influenced by the timing of its initiation?

• A. The sooner CPR is started, the better the chances of survival
• B. CPR is only effective if started within the first hour
• C. The timing does not affect survival chances
• D. CPR should only start after the emergency team arrives

Answer: (A)

The effectiveness of CPR is significantly influenced by the timing of its initiation. When CPR is started immediately after a person experiences cardiac arrest, it helps maintain blood flow to vital organs, especially the brain. This is crucial because brain cells can begin to die within minutes without oxygen-rich blood. Studies consistently show that the sooner CPR is administered, the better the chances of survival and recovery for the individual. Timely intervention can buy critical time until emergency medical services arrive and take over with advanced care. The chances of a favorable outcome decrease drastically the longer it takes to initiate CPR. This is why immediate action is emphasized in CPR training; early and effective CPR is a vital link in the chain of survival.
