The main function of AED is defibrillation, which can be divided into two types: automatic and semi-automatic. It can automatically analyze the heart rhythm, adjust the energy and judge whether defibrillation is needed. Because it is simple to use, it is often used in public places such as subways, schools, shopping malls and parks.
Defibrillators are also called manual defibrillators or defibrillation monitors, which have more configurations and functions than aed. For example, we often see doctors holding electric irons when rescuing patients on TV, which must be used by trained professional medical staff, and decide whether to leave the hospital and choose energy level according to ECG changes. At the same time, the defibrillator has many functions, such as synchronous cardioversion, pacing, monitoring, and even some plug-ins can measure blood pressure, oxygen saturation, end-expiratory carbon dioxide and so on. Generally used in hospitals, ambulances and clinics.
AED is mainly used for patients with ventricular fibrillation without response, breathing and pulse and patients with ventricular tachycardia with heart rate greater than 180 beats/min. Simply put, AED is effective when the heart beats abnormally, but it will not act on the heart that stops beating completely.
If it is difficult to judge the patient's condition, you can open the AED step by step, paste the electrode pads, wait for the heart rhythm analysis of the AED, and follow the voice prompts of the AED.
If the AED prompts that no electric shock is needed, but the patient still doesn't breathe or respond, please continue cardiopulmonary resuscitation.
