Using a defibrillator

A cardiac defibrillator is a device used to treat a person in cardiac arrest. The device seeks to return the heart to its normal function using an electric shock.

Automatic external defibrillators (AEDs) intended for the use of everyone are available at several workplaces and public places. The device must be in an accessible location, signposted with the “AED” sign.

The electric shock administered by a defibrillator is intended to interrupt a potentially fatal arrhythmia of the heart to allow the heart to restart and resume its normal rhythm.

After starting the defibrillator, the device provides the user with verbal instructions, making its use simple and safe.

Applying the electrode pads

The defibrillator administers its electric shock to the heart via electrode pads that can be applied to the chest.

The electrodes included with the device are stuck on to the person’s bare chest as instructed in the package.

Analyse the cardiac rhythm

The defibrillator will analyse the cardiac rhythm of the person and decides if a brief electric shock is necessary to restore normal cardiac function. If the shock is not necessary, the device will guide the helper to resume CPR as uninterrupted as possible.

The defibrillator will not administer the shock automatically; rather, the helper must push the flashing “shock” button when instructed to by the device. The defibrillator will guide the helper through the process with clear verbal commands and ask them to not touch the person being helped when the shock is to be administered.

The defibrillator will analyse the patient’s heartbeat every two minutes. In between the analyses, the device directs the helper to apply compressions.

The defibrillator will also guide the helper to take further action after the heart is restarted.
