The number ofconductors in, on, ad mound patients. Such as 80 catheters, wet dressings, CVP lines, Pacemakers. F. Must have a knowledge of electrical safety to protect the patient, others, and yourself G. Electric current consists of a flow of electrons through a conducting pathway or circuit. The circuit must be closed with a difference in potential existing between two points. The amount of current flowing between two points of different electrical potential vdes inverseb with the intervening resistance.
Resistance is the impedance to flow.
When resistance is low lmge amounts of current flow and inversely when resistance is I. Electricity is carried into the hospital via a hot line and is carried back to the power source via a neutral line. When a 3-wire system is used a ground is used. A ground works to transfer all excess leakage of current to the ground. Ah electrical current leaks. The mnount of current is reeulated and is hannless ifthe eouinment is nronerlv mounded.
