Question

What is the advantage of biphasic over monophasic defibrillation?

1) Biphasic defibrillation requires less energy than monophasic defibrillation.
2) Biphasic defibrillation has a higher success rate than monophasic defibrillation.
3) Biphasic defibrillation is more effective in converting ventricular fibrillation to normal sinus rhythm than monophasic defibrillation.
4) Biphasic defibrillation has fewer adverse effects than monophasic defibrillation.

Answer 1

Biphasic defibrillation offers advantages over monophasic defibrillation, including requiring less energy, having a higher success rate, and causing fewer adverse effects.

Step-by-step explanation:

Biphasic defibrillation has several advantages over monophasic defibrillation:

1. Less energy: Biphasic defibrillation requires less energy than monophasic defibrillation to achieve the same success rate. This means that the electrical shock delivered to the heart is more efficient and causes less damage to the surrounding tissues.
2. Higher success rate: Biphasic defibrillation has been found to have a higher success rate in restoring normal sinus rhythm compared to monophasic defibrillation. This means that it is more effective in treating ventricular fibrillation and increasing the chances of survival.
3. Fewer adverse effects: Biphasic defibrillation has been associated with fewer adverse effects, such as burns and injuries to the heart tissue, compared to monophasic defibrillation.
