After CPR has been initiated, when is it appropriate to use an AED?

Using an AED (Automated External Defibrillator) as soon as it is available, regardless of CPR status, is crucial in a cardiac arrest situation. The effectiveness of the AED in identifying shockable rhythms such as ventricular fibrillation or pulseless ventricular tachycardia is maximized when it is utilized early in the resuscitation effort.

Prompt access to an AED can significantly enhance the survival chances of a patient experiencing a cardiac arrest. The device is designed to analyze the heart's rhythm and deliver a shock if necessary, thereby restoring a normal rhythm more effectively when used quickly. Employing the AED without delay ensures that defibrillation occurs as soon as possible, which is a key factor in successful outcomes.

While performing CPR is essential and should continue, having the AED brings an additional life-saving intervention into the equation. This underscores the importance of integrating both CPR and defibrillation in the emergency response to cardiac arrest.
