What is the recommended energy dosage for biphasic defibrillators when defibrillation is indicated?

The recommended energy dosage for biphasic defibrillators when defibrillation is indicated is 120 to 200 Joules. This range has been established based on clinical studies showing that these energy levels are effective for defibrillation in patients experiencing shockable rhythms, such as ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT).

Biphasic defibrillation works by delivering shocks that are controlled in a way that allows the electrical current to pass through the heart effectively, increasing the chances of restoring a normal rhythm. The 120 to 200 Joules range has been found to provide a good balance between efficacy and safety, minimizing the risk of potential damage to the myocardial tissue while maximizing the likelihood of successful defibrillation.

Other energy levels outside this range, while still noted in historical contexts or in specific cases, may not align with the latest standards set by resuscitation guidelines, which emphasize the updated efficacy of using biphasic defibrillators at these recommended dosages for optimal patient outcomes.
