How long should a rescuer wait for a response before initiating CPR?

The recommended waiting time before initiating CPR is approximately 10 seconds. During this period, the rescuer assesses the victim for responsiveness and checks for signs of breathing. If the individual does not respond to verbal cues or physical stimulation, and there are no signs of normal breathing, it is critical to begin CPR without delay. The 10-second timeframe is sufficient for a rescuer to determine if the person is unresponsive, allowing for a swift transition to CPR to improve the chances of survival, especially in cases of cardiac arrest. This quick response can make a significant difference in outcomes, highlighting the importance of an efficient assessment process.
