An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
An AED is a lightweight, portable device that delivers an electric shock through the chest to the heart when it detects an abnormal rhythm. Its purpose is to change the rhythm back to normal ...
Based on death certificates, sudden cardiac death accounts for about 20% of all deaths in the United States. [ 152 ] [ 153 ] In the United States, approximately 326,000 cases of out-of-hospital and 209,000 cases of IHCA occur among adults annually, which works out to be an incidence of approximately 110.8 per 100,000 adults per year.
Basic life support (BLS) is a level of medical care which is used for patients with life-threatening condition of cardiac arrest until they can be given full medical care by advanced life support providers (paramedics, nurses, physicians or any trained general personnel).
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
There are only 10–20 cases annually in the United States. [1] These cases occur mostly in boys and young men (mean age 15), usually during sports participation. [1] It occurs most frequently in baseball when the hard ball strikes an unprotected chest, although there have been cases of commotio cordis in players using a chest protector. [1]
Rapid defibrillation outside of the hospital improves the chances of survival by as much as 30%, and involves using an automated external defibrillator (AED) to shock the patient's heart. [16] While CPR keeps blood flowing artificially, [17] rapid defibrillation is the only way to restart the heart and reset it to a healthy rhythm. [18]
Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare. [6] [7] Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored ...
