When a person has no pulse, no breathing, and no consciousness, it is known as a sudden cardiac arrest. In such a situation, an immediate Cardiopulmonary Resuscitation (CPR) and a defibrillation are needed. CPR includes the chest compressions and rescue breathing, which aims to ensure the oxygen flow to the brain and avoid the brain damage to the victim. A defibrillation is an electrical current (shock) applied on the victim’s chest to help the heart to reorganize its electrical activity in pumping blood again.
What is an AED?
Automated External Defibrillator (AED) is a portable device that can analyze the heartbeat automatically and give advice to the rescuer whether to deliver a shock to the victim. The electrode pad of AED will be stuck on the victim’s chest and shock is delivered after analyzation.
Some advanced AED can identify the effectiveness of CPR delivered by giving the real-time feedback to the rescuer’s chest compressions. When both AED and CPR working together, this could increase the chance of survival for the victim.
How to Use an AED?
- When the AED arrives, turn it on and open the lid.
- Remove all the clothing on the victim’s chest area. Make sure the chest is dry and remove excess hair.
- Take out the electrode pads and place it on the victim’s chest. Make sure the “+” sign is in the middle of the chest.
- When the AED is analyzing the victim’s heartbeat, make sure no one is touching him.
- If the AED advises to deliver a shock, press the shock button (make sure no one is touching the victim).
- If the AED does not advise a shock, start to do CPR immediately. After a complete cycle of CPR (30 chest compressions & 2 breathings), AED will analyze the victim’s heartbeat again, and either advise a shock or continue to do CPR.
- Follow the instructions given by AED until the victim regains consciousness or the ambulance arrives.
The Importance of AED
AED could increase the chance of survival when a sudden cardiac arrest occurs. It is because the ambulance and the medical devices may not arrive on time at the scene. However, in Malaysia, only airports and some shopping malls have this device. AED should be available in more public places, or even workplace and residence areas.
