What doesmonophasic defibrillator mean?

A monophasic defibrillator is a medical device used to deliver a single, high-energy electric shock to the heart during life-threatening arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia. Unlike biphasic models, it sends current in one direction through the heart. Though largely replaced by biphasic defibrillators, monophasic units are still found in some settings due to cost-effectiveness and ease of use. A typical kit includes the defibrillator unit, electrode pads or paddles, a power source, ECG monitor, and user instructions. It’s essential for emergency response, especially in environments with limited access to advanced cardiac life support equipment.
