How To Save A Cardiac Arrest Victim?

Each year, there are between 300,000 and 400,000 deaths in the United States from cardiac arrest. Most cardiac arrest deaths occur outside the hospital. The current out-of-hospital survival rates are very low: between 1 and 5 percent.

Cardiac arrest usually occurs when the heart's electrical activity becomes disrupted and the heartbeat gets dangerously fast (ventricular tachycardia) or chaotic (ventricular fibrillation). As a result, irregular heart rhythm (arrhythmia) occurs and the heart stops beating effectively and cannot adequately pump blood. But if an electric shock from an AED can be delivered in time across the chest and through the heart, the fatal rhythm of ventricular fibrillation can be turned back to a normal rhythm.

An AED (automated external defibrillator) is a device that can be attached to a person’s chest. It can sense the heart's rhythm during cardiac arrest and in some cases, deliver an electric shock to get the heart beating again. The device, when used together with CPR (cardiopulmonary resuscitation) by trained persons offers the best chance of survival for a person who suffers a sudden cardiac arrest. CPR can keep some blood flowing to the heart and brain for a short time.

People who has a cardiac arrest will suddenly lose consciousness. So when one sees someone pass out, the first thing he or she should do is to check whether the victim is unconscious and not breathing. Once confirmed the victim is unresponsive, an ambulance should be called immediately and an AED should be secured right away. AEDs are now commonly available in many public places including the shopping malls, office buildings, sports arenas, golf courses, schools, and airports and airplanes.

CPR should then be started on the victim until the AED arrives. Once the device is switched on, voice prompts will advise what to do. Sweat, if any, should be wiped from the chest of the victim before attaching the electrode pads to the bare chest. The first pad should be placed on the victim's upper right side, just below the collarbone, while the second pad is placed just below and to the left of the left nipple. The device will advise if shock is advised. If shock is required, the helper should make sure no one is touching the victim before pressing the button. The helper should continue to follow the voice prompts until the ambulance arrives.

Nevertheless, one should note that an AED can only for certain types of cardiac arrest that involves specific types of heart fibrillation, and it will not revive everyone in cardiac arrest.
