A Defibrillator Circuit Shocks the Heart

Automated defibrillators save lives and the defibrillator circuit provides the needed energy to do so. Defibrillators shock the heart back into a general heart rhythm after a disruption such as cardiac arrest. Research shows that in order to best save lives, a unit has to supply a shock fast, at the permissible dose, and adjust to changing obstacles.

In a conveyable automatic defibrillator, such as those used in schools and other businesses, the source of electricity for the shock is a battery. But in order to change that energy to a sick person in a beneficial waveform, a defibrillator circuit needs to operate. The waveform can be belief of a changing pattern in the current, so that a literal, dose is administered throughout the shock and despite any impedance that the shock encounters.

The circuitry in the defibrillator connects the payment in the middle of the battery and the patient's chest. The current flows straight through the defibrillator pads to shock the heart. Population often think that a person's body weight increases impedance to the current, creating a situation where more electricity is needed to supply a literal, and consistent shock to the heart. However, Research has not backed this up. The American Heart connection states that there is no evidence of a connection in the middle of body weight and impedance.

Many defibrillators are now using a biphasic waveform rather than the older monophasic waveform. In a biphasic defibrillator, the circuit sends an electrical current that follows from paddle to paddle in both directions. With monophasic waveforms, the current went only from one paddle to the other, but it did not return in the other direction. Research has shown that biphasic waveforms are more effective.

Patients with an implanted defibrillator do need to be cautious if they receive radiation therapy. The radiation can potentially damage the defibrillator circuit, but this can be prevented if the area is shielded or moved to someone else area. In general, today's models are not effected by interference from other sources, like microwaves.

A defibrillator circuit is an important part of the defibrillator. Without the circuit, the defibrillator would not be able to deliver a therapeutic dose of electricity to the heart. Thus, it could be said that the defibrillator circuit is the reckon lives are saved by shocks to the heart.
