DefibrillationDefibrillation

Definition:

Defibrillation is a process in which an electronic device sends an electric shock to the heart to stop an extremely rapid, irregular heartbeat, and restore the normal heart rhythm.

Purpose:

Defibrillation is performed to correct life-threatening fibrillations of the heart, which could result in cardiac arrest. It should be performed immediately after identifying that the patient is experiencing a cardiac emergency, has no pulse, and is unresponsive.

Precautions:

1. Defibrillation should not be performed on a patient who has a pulse or is alert, as this could cause a lethal heart rhythm disturbance or cardiac arrest.

2. The paddles used in the procedure should not be placed on a woman's breasts or over a pacemaker

DefibrillationDefibrillation

Mechanism:

Fibrillations cause the heart to stop pumping blood, leading to brain damage.

Defibrillators deliver a brief electric shock to the heart, which enables the heart's natural pacemaker to regain control and establish a normal heart rhythm.

Preparation:After help is called for, cardiopulmonary

resuscitation (CPR) is begun and continued until the caregivers arrive and set up the defibrillator.

Electrocardiogram leads are attached to the patient's chest.

Gel or paste is applied to the defibrillator paddles, or two gel pads are placed on the patient's chest.

The caregivers verify lack of a pulse.

Care after defibrillation:The patient's cardiac status, breathing, and vital

signs are monitored until he or she is stable. An electrocardiogram and chest x ray are taken. The patient's skin is cleansed to remove gel or

paste, and, if necessary, ointment is applied to burns.

An intravenous line provides additional medication, as needed.

Complications:

Skin burns from the defibrillator paddles are the most common complication of defibrillation.

Other risks include injury to the heart muscle, abnormal heart rhythms, and blood clots.

PROCEDURE FOR DEFIBRILLATION:Provided by nursing staff that are certified to

perform defibrillation. The success of resuscitation of patients with

ventricular fibrillation relates to how fast electrical defibrillation can be applied.

The longer the duration of fibrillation, the greater the deterioration of the myocardium, because a fibrillating heart consumes a very large amount of oxygen.
