What is the appropriate defibrillation energy for Biphasic shocks?

Biphasic defibrillation is designed to deliver electrical shocks in a more efficient manner compared to monophasic systems. The energy levels used for biphasic defibrillators typically range within a specified range, and the recommended setting is usually around 200 joules. This is because biphasic waves are shown to be effective at lower energy levels, allowing for successful defibrillation with fewer complications.

The 200 joules setting is a well-established guideline supported by clinical studies. This energy level effectively depolarizes the heart to restore a normal rhythm while minimizing the risk of myocardial injury or other adverse effects associated with higher energy levels. The effectiveness of this shock setting balances the need for efficacy in terminating life-threatening arrhythmias while maintaining safety for the patient.

In contrast, higher energy settings—such as those above 200 joules—may carry increased risks and are generally not necessary for biphasic devices. Therefore, 200 joules is recognized as the standard and appropriate energy level for administering biphasic shocks in critical care settings.
