How long should you check for a pulse when starting CPR?

When beginning CPR, it is essential to check for a pulse for no longer than 10 seconds. This timeframe is established to ensure that the responder does not waste valuable time that could be used for initiating lifesaving interventions. If no pulse is detected within that period, the recommendation is to immediately start chest compressions.

This approach aligns with guidelines from organizations like the American Heart Association, emphasizing the urgency of starting CPR promptly, especially in cases of cardiac arrest, where every second counts. Spending more than 10 seconds checking for a pulse could lead to unnecessary delays, which might reduce the chances of survival for the patient. Recognizing that immediate action is typically more beneficial helps preserve oxygenated blood flow to vital organs until advanced care can take over.
