How soon should a medic initiate CPR after determining a patient is unresponsive?

Initiating CPR immediately after determining a patient is unresponsive is critical for maximizing the chances of survival in cases of cardiac arrest. The recommendation to start CPR ideally within 10 seconds is based on the understanding that brain damage can begin within minutes of oxygen deprivation. The sooner CPR is started, the sooner circulation is restored, which provides oxygen to the brain and other vital organs.

In emergency situations, time is of the essence. Immediate chest compressions help maintain blood flow to the heart and brain until advanced medical help arrives or an automated external defibrillator (AED) can be applied. The focus is on acting swiftly to ensure that the patient receives the necessary support to prevent irreversible damage.

Other time frames suggested, such as waiting 30 seconds or longer, can significantly increase the likelihood of severe outcomes for the patient, making immediate action of utmost importance. Checking for a pulse for an extended period before starting CPR delays critical interventions that could save a life. Thus, immediate action is not only a best practice but a life-saving necessity.
