An automated external defibrillator or AED Unit is a portable electronic device that automatically diagnoses the potentially life threatening cardiac rhythms.
The AED machine is able to treat patients by defibrillation which is the application of electrical therapy.
Defibrillators can stop arrhythmia and allow the heart to reestablish an effective blood-pumping rhythm.
AED's are designed to be simple and easy to use for laypersons. Most CPR and First Aid courses or basic life support (BLS) courses teach layperson responders how to use an automated external defibrillator.
Heart disease is a common problem that we should not ignore. It is important to prepare for every emergency because scuba diving vacations are often taken in remote locations that may be some distance from emergency medical assistance.
Note: According to Divers Alert Network (DAN) the average age for scuba diving fatalities is gradually increasing (42 years old).
