In the simplest language, when a unidirectional wave defibrillator discharges, the current flows in one direction from one electrode plate to the other, and the current does not change direction during this process. In a bidirectional wave defibrillator, the current changes direction once during discharge and does not always flow in one direction. It is currently believed that bidirectional wave defibrillators can achieve higher defibrillation success rates with lower electrical energy and produce relatively less myocardial damage.
A defibrillator is a medical device that uses strong pulse current to pass through the heart to eliminate arrhythmia and restore sinus rhythm. It is a necessary emergency equipment in the operating room. Defibrillation is one of the most important steps in performing cardiopulmonary resuscitation.
The defibrillator is mainly composed of a monitoring part, a cardioversion machine, electrode plates, batteries and other parts. An electrical cardioversion machine, also called a defibrillator, is the main equipment for performing electrical cardioversion. Equipped with electrode plates, most of them come in two pairs, large and small, the larger one is suitable for adults and the smaller one is suitable for children.
