aed first aid equipment is an automated external defibrillator, also known as an automated external defibrillator, automated defibrillator, etc., which is a portable medical device.
Automated external defibrillators, also known as automated external defibrillators, automated defibrillators, automatic defibrillators, cardiac defibrillators and defibrillators for dummies, etc., are portable medical devices that diagnose specific cardiac arrhythmias and administer defibrillating shocks, and are medical devices that can be used by non-professionals to resuscitate patients with sudden cardiac arrest.
In cardiac arrest, defibrillation and cardiopulmonary resuscitation (CPR) using an automated external defibrillator (AED) is the most effective way of stopping sudden death only in the "golden four minutes" of the optimal resuscitation time. According to some data, the success rate of using AEDs to treat cardiac arrest patients before they are sent to the hospital can reach 94%.
AUTOMATIC EXTERNAL DEFIBRILLATOR (AED) USE:
Unlike the specialized defibrillators found in hospitals, AEDs require only a short period of instruction to use. The machine itself automatically reads the electrocardiogram and then decides whether a shock is needed. Fully-automated models even require only that the rescuer apply a shock patch to the patient before it determines and delivers the shock. Semi-automatic models remind the rescuer to press the shock button.
In most cases, the machine won't deliver a shock even if the rescuer presses the button by mistake, and some models can be used on children (less than 25 pounds or younger than 8 years old), but they generally must be fitted with child-specific electrode patches. The American College of Cardiology recommends that adult patches be used instead, even if child-specific patches aren't available; there's no evidence that adult patches cause more serious damage.
Automated external defibrillators in the U.S. use machine-synthesized speech to give instructions to the rescuer. But because the rescuer may be hearing-impaired, hard-of-hearing, or unable to understand English, many models also have screens that provide messages and graphics to alert the rescuer. Most models are designed for non-medical personnel. The automated external defibrillator (AED) is the most important invention since cardiopulmonary resuscitation (CPR), which made cardiac emergencies accessible to the general public.
