hjertestarter

A hjertestarter, commonly known as an automated external defibrillator (AED) in many countries, is a portable device designed to treat sudden cardiac arrest. It analyzes the heart’s rhythm and, if needed, delivers an electrical shock to restore a normal rhythm, typically for rhythms such as ventricular fibrillation or pulseless ventricular tachycardia.

AEDs are intended for use by laypeople with minimal training. They provide spoken and visual prompts, guide pad placement on the chest, and determine whether a shock is appropriate. The device will not deliver a shock unless it detects a shockable rhythm.

Public access and maintenance: AEDs are increasingly installed in schools, offices, shopping centers, airports, and other public places. Regular maintenance includes checking battery status, ensuring pad expiry, and replacing supplies after use. Data recovery and incident reporting may be required by authorities.

Usage in an emergency: Call emergency services, begin CPR if trained, turn on the AED, attach the adhesive pads to the bare chest (one pad on the upper right chest, the other on the lower left chest), and follow the device’s prompts. Stand clear during shock delivery.

Impact and regulation: Early defibrillation within minutes markedly improves survival from sudden cardiac arrest. Training in CPR and AED use is encouraged, and many jurisdictions provide legal protection for bystanders acting in good faith. AEDs are subject to safety standards and maintenance requirements.
