What Is a Portable Defibrillator?

Automatic external defibrillator, also known as automatic external shock device, automatic shock device, automatic defibrillator, cardiac defibrillator, and fool stunner, is a portable medical device that can diagnose specific arrhythmias and give electric shock Defibrillation is a medical device that can be used by non-professionals to rescue patients with cardiac arrest. During cardiac arrest, only within the "golden 4 minutes" of the best rescue time, using an external external defibrillator (AED) to defibrillate and resuscitate the patient is the most effective way to prevent sudden death.

Unlike professional defibrillators in hospitals, automatic external defibrillators require only short-term instruction to use. The machine itself reads the ECG and decides whether an electric shock is needed. The fully automatic model only requires the rescuer to put an electric shock patch on the patient, and it can judge and generate an electric shock by itself. The semi-automatic model will remind the rescuer to press the shock button. In most cases, even if the rescuer presses the shock button by mistake, the machine will not make an electric shock. Some models can be used on children (under 25 kg or less than 8 years old), but generally, children must choose Electrode patch. The American College of Cardiology recommends that adult patches be used instead of child-specific patches; there is no evidence that patch electrodes for adults can cause more serious damage.
Automatic external defibrillators in the United States use machine-synthesized speech to give instructions to rescuers. But because the rescuer may be
1. Turn on the AED, open the cover of the AED, and follow the visual and sound prompts (some models need to press the power first).
2. Stick the electrode to the patient, and stick the electrode tightly on the patient's chest. Generally speaking, two electrode plates are attached to the upper part of the right chest and the left side of the left breast and the left nipple. For specific positions, refer to the pictures on the AED chassis and the pictures on the electrode boards. There are also AEDs that use integrated electrode plates, such as the ZOLL AED Plus, which will be deployed at the Beijing Olympics venue.
1. The AED can reach an energy of 200 joules in an instant. In the rescue process for the patient, please keep away from the patient immediately after pressing the power-on button, and warn anyone around you not to touch the patient.
2. Patients cannot use AED in water. If there is sweat on the chest of the patient, the chest needs to be dried quickly because water will reduce the efficacy of AED.
3. If after using the AED, the patient does not have any vital signs (no breathing heartbeat), they need to be sent to the hospital for treatment immediately.
Automatic defibrillators are usually deployed in places with large crowds, such as shopping malls, airports, stations, restaurants,
  • attach pads
  • do not touch the patient, analyzing ECG / rhythm (please do not touch the patient, ECG / rhythm is being analyzed)
  • shock advised / no shock advised
  • stand clear (away from the patient)
  • charging
  • press the shock button
  • shock delivered
  • check patient, if no pulse do CPR
