What is the maximum time for delivering a shock with an AED?

The maximum recommended time for delivering a shock with an AED (Automated External Defibrillator) is 10 seconds. This guideline is based on the understanding that time is critical in cardiac arrest situations, and prolonged pauses in chest compressions can negatively impact the patient’s chances of survival. Quick and efficient delivery of shocks is essential to restore a normal heart rhythm.

The 10-second guideline allows for the necessary time to ensure that the AED has properly analyzed the heart rhythm and is ready to deliver a shock if indicated, while also minimizing interruption of high-quality CPR. This timing is crucial because effective CPR helps maintain blood flow to vital organs until defibrillation can be administered. Proper adherence to these time limits optimizes patient outcomes in emergency situations.
