What is a monophasic defibrillator?
Sometimes the heart rhythm of a person who is controlled by electric pulses becomes irregular and very fast. Sometimes this irregularity, called chamber fibrillation, can cause the heart to stop completely. The heart can also be stopped by a surgeon during an open heart operation. Doctors use a defibrillator to restart the heart or attempt to restore a regular heart rhythm with an electric shock to the heart. Monophasic defibrillator is a type commonly used in many hospitals; Monophasic means that its electricity is only one direction - to create a shock.
defibrillators can be external or can be implanted. The external defibrillator has four primary parts: monitor, capacitor and either two paddles or two sticky defibrillation pads. The capacitor adds an electricity that travels from one paddle or pillow over the heart to the other paddle or pad. The monitor allows the doctor to observe what is happening with the heart rhythm.Noing the same as the pacemaker, although the pacemaker mayI have part of the implanted defibrillator. The cardiceker controls the heart rhythm, so it is not too fast or too slow, while the defibrillator part of the device shocks the heart to help it restore normal pace when something becomes out of the pacemaker control. The implanted monophasic defibrillator was not originally included in the pacemaker.
Monophasic defibrillator must use a fair amount of electricity to give the heart enough electricity to restore normal function; This electricity can cause skin burns, so doctors try to use the least effective amount. The American Heart Association (AHA) recommends from 360 joules of electricity, although other instructions begin up to 50. As an example of how much electricity is used in defibrillation, some people to start the engine in a diesel car.
Another type of defibrillator is a biphasic defibrillator. He also gives the heartThe only electric shock, but as in alternating jet electricity, half of the shock in one direction goes and the other half goes in the opposite direction. In other words, it goes from one paddle, through the heart to the other paddle and then back.
Studies indicated that a smaller number of jouls using a biphasic defibrillator will work and a larger amount of a monophasic defibrillator. Using less power means that the battery lasts longer, so biphasic shocks are used in implanted defibrillators. The permanent beneficial effects of the use of a monofasical defibrillator or biphasic defibrillator are the same.
