Question

Energy for monophasic vs biphasic defibrillation

Monophasic: higher energy required
Biphasic: lower energy required
Monophasic: lower energy required
Biphasic: higher energy required

Answer 1

Monophasic defibrillation requires higher energy, while biphasic defibrillation requires lower energy to deliver an electric shock and restore a normal heart rhythm.

Step-by-step explanation:

In defibrillation, both monophasic and biphasic waveforms are used to deliver an electric shock to the heart to restore a normal heart rhythm. The main difference between monophasic and biphasic defibrillation is the amount of energy required. Monophasic defibrillation requires higher energy, while biphasic defibrillation requires lower energy.

For example, a monophasic defibrillator may require 360-400 joules of energy to deliver a shock, while a biphasic defibrillator may only require 120-200 joules of energy. This means that biphasic defibrillation is more efficient as it requires less energy to achieve the desired outcome.

Overall, the choice between monophasic and biphasic defibrillation depends on various factors including the patient's condition, the type of cardiac rhythm disturbance, and the availability of the equipment.
