Explain The Interaction Between The Key Components Of A Defibrillator
DEFIBRILLATOR
Definition
An electronic device that administers an electric shock of preset voltage to the heart through the chest wall in an attempt to restore the normal rhythm of the heart during ventricular fibrillation. Defibrillation is a procedure used to treat life threatening conditions that affect the rhythm of the heart such as cardiac arrhythmia, ventricular fibrillation and pulseless ventricular tachycardia.
The procedure involves the delivery of an electric shock to the heart which causes depolarisation of the heart muscles and re-establishes normal conduction of the heart’s electrical impulse. The machine used to deliver this therapeutic shock to the heart is called a defibrillator.

These three components will be explored in depth. Specifically, the interaction between these three components is what allows defibrillators to effectively restore proper cardiac rhythms.
I.) Capacitors: One of the key components of a defibrillator is a capacitor. The capacitor of a defibrillator stores a large amount of energy in the form of electrical charge. Then, over a short period of time, the capacitor releases the stored energy. The capacitor itself contains numerous components: a pair of metal plate conductors and an insulator. The insulator is in the middle of the conductors and does not loose electrons. On the other hand, conductors easily loose electrons and promote current flow.
When the switch is in position 1, direct current from the power supply is applied to the capacitor and electrons flow. Therefore current flows and a charge begin to build up on each electrode of the capacitor. Specifically, the lower plate is more negative and the upper plate is more positive. The build-up of opposing charges creates a potential difference across the plates (V) that opposes the electromagnetic force of the power supply
