What is the primary goal of using a biphasic defibrillator?

• A. To minimize patient discomfort during defibrillation
• B. To increase the likelihood of restoring normal heart rhythm
• C. To restrict shocks to one per episode of ventricular fibrillation
• D. To decrease the time spent during the defibrillation process

Answer: (B)

The primary goal of using a biphasic defibrillator is to increase the likelihood of restoring normal heart rhythm. Biphasic defibrillators deliver a shock that flows in two directions, which has been shown to be more effective at terminating certain types of arrhythmias. Studies have demonstrated that biphasic waveforms require lower energy levels compared to monophasic defibrillators, while still achieving a similar or higher success rate in restoring a normal cardiac rhythm. This increased efficacy is crucial during critical situations, such as cardiac arrest, where every second counts for improving patient outcomes. While minimizing patient discomfort is a consideration in defibrillation, the primary objective is focused on the effectiveness of restoring the heart's normal rhythm. The other options either provide lesser priorities or are not aligned with the core purpose of biphasic defibrillation.
