In cases of cardiac arrest, it may take several shocks from a defibrillator for the heart to return to its normal rhythm. Since every individual is different, the number of shocks needed can vary from person to person.
The primary distinction between an AED and a defibrillator lies in the intended user. Both devices serve the same purpose : to restore a person’s normal heartbeat. AEDs are designed for use by untrained bystanders during a cardiac arrest emergency, while defibrillators are intended solely for trained medical professionals and are typically found in settings such as hospitals and ambulances. Doctors, nurses, and paramedics generally use manual defibrillators, which require specific training to evaluate and treat different heart arrhythmias.
An AED can be used on a wet surface, although it is not recommended. There are concerns about potential electrical shock hazards when using an AED on a wet surface.
Whenever possible, defibrillation should be done on a dry surface. Bystanders not involved in the rescue should move away from the wet surface. If it is not possible to move the patient to a dry surface quickly and safely, rescuers who must remain on the wet surface should follow safety protocols to ensure defibrillation with the AED is safe. This includes avoiding direct contact with the patient, properly applying the self-adhesive pads, and ensuring the patient's chest is dry with no water between the pads.
This refers to placing an AED in a public space, which could be any location where people frequently gather. Ideally, these devices should be installed in areas with a high risk or occurrence of cardiac arrest, or in places where it is difficult for the Ambulance Service to reach.
An AED is designed to be user-friendly and can be used by individuals with minimal or no training. Once the AED is turned on, it will guide the user through the process with audible instructions and visual indicators.
AEDs are lifesaving devices used to assist individuals experiencing sudden cardiac arrest. These easy-to-use devices assess the heart's rhythm and, if necessary, administer a shock (defibrillation) to restore a normal heartbeat. Designed for ease of use, AEDs provide clear instructions for operation during an emergency. It’s crucial for everyone to understand what an AED is and how to use it, as it could play a critical role in saving a life.
Most individuals who experience cardiac arrest had one or more symptoms in the hour leading up to the event. Some symptoms may even appear weeks before a cardiac arrest occurs. However, many people who suffer a cardiac arrest show no prior warning signs.
Possible warning signs of a heart attack, which is a major cause of cardiac arrest, include the following:
- Shortness of breath (more common in women than men)
- Extreme fatigue or unusual tiredness
- Back pain
- Flu-like symptoms
- Stomach pain, nausea, and vomiting
- Chest pain, especially angina (more common in men than women)
- Frequent dizziness or fainting, particularly during intense exercise, while sitting, or lying on your back
Cardiac arrest is particularly concerning for children and infants because their vital organs are still developing. As it can lead to sudden death without warning, it’s crucial to recognize the signs early and know how to apply AED pads on an infant. When children and infants experience cardiac arrest, their heart rhythm becomes erratic, often resulting in ventricular fibrillation, which causes the heart to stop functioning properly. In these situations, a defibrillator is the most effective tool to restore normal heart rhythm and save their life. Prompt recognition and action are key to giving the child the best chance of survival

AED stands for automated external defibrillator.

It is likely that a person is having a cardiac arrest if they:
- Collapse suddenly and lose consciousness (pass out)
- Are not breathing or their breathing is ineffective or they are gasping for air
- Do not respond to shouting or shaking
- Do not have a pulse
