AED is an automated external defibrillator, a portable medical device that can diagnose specific cardiac arrhythmia and implement defibrillation by electric shock, which can be used by healthcare personnel, or by personnel qualified to receive relevant first aid training, or by ordinary people under the guidance of professionals.
The main function of AED is defibrillation, which is divided into full-automatic and semi-automatic, and can automatically analyze the heart rhythm, automatically adjust the energy, and automatically determine whether defibrillation is needed. Because of its simplicity of use, it is mostly used in subways, schools, shopping malls, parks and other public **** places.
Defibrillator is also called manual defibrillator or defibrillation monitor, configuration and function compared to the AED more, for example, we often see in the TV doctors in the rescue of patients with a device like an iron, must be used by trained medical professionals, according to the changes in the electrocardiogram, to decide whether to discharge as well as to choose the size of the energy and so on. At the same time defibrillator also has many functions, such as: synchronized electrical cardioversion, pacing, monitoring, and even add some plug-ins can also measure blood pressure, oxygen saturation, end-expiratory carbon dioxide, etc., the use of the place is generally in hospitals, ambulances and clinics.
AEDs are mainly used for patients with ventricular fibrillation who do not respond, breathe, or have a pulse, as well as patients with ventricular tachycardia whose heart rate is greater than 180 beats per minute. Simply put, an AED is effective when the heart is beating abnormally, but will not work on a heart that has stopped beating completely.
If it is difficult to determine the patient's condition, you can follow the steps to turn on the AED, attach the electrode pads, and wait for the AED's rhythm analysis as well as follow the AED's voice prompts.
If the AED prompts that a shock is not needed, but the patient is still not breathing and unresponsive, continue CPR.
