How quickly should CPR be initiated after cardiac arrest?

• A. Within a minute of recognizing the arrest
• B. Immediately, within seconds of recognizing the arrest
• C. After calling emergency services
• D. Once an AED is available

Answer: (B)

Initiating CPR within seconds of recognizing cardiac arrest is critical because the chances of survival decrease rapidly with each passing minute. Cardiac arrest leads to a cessation of blood flow, which can result in brain damage or death within minutes. The primary goal of CPR is to maintain circulation and oxygenation of the vital organs until professional medical help arrives. Starting CPR immediately allows the pumping of oxygenated blood to the heart and brain, significantly increasing the chance of survival. This urgency is why guidelines emphasize that CPR should be started as soon as the cardiac arrest is recognized, rather than waiting for further action such as calling emergency services or the availability of an AED. Time is a key factor in resuscitation, and immediate action is essential for improving outcomes in cardiac arrest situations.
