defibrillaattorijärjestelmä

A defibrillator system is a medical device designed to deliver an electrical shock to the heart. This shock can correct certain life-threatening cardiac arrhythmias, such as ventricular fibrillation and pulseless ventricular tachycardia, which prevent the heart from pumping blood effectively. When a person experiences sudden cardiac arrest, their heart rhythm may become chaotic. A defibrillator analyzes the heart's electrical activity and, if a shockable rhythm is detected, delivers a controlled electrical current.

There are several types of defibrillator systems. Automated external defibrillators (AEDs) are designed for public use and can be operated by individuals with minimal medical training. They provide voice and visual prompts to guide the user through the process. Manual defibrillators require a trained medical professional to interpret the heart rhythm and decide whether to deliver a shock. Implantable cardioverter-defibrillators (ICDs) are surgically implanted devices that continuously monitor heart rhythm and can deliver a shock automatically if a dangerous arrhythmia is detected.

Defibrillator systems are crucial components of emergency medical services and are increasingly found in public spaces like airports, shopping malls, and sports venues. Prompt defibrillation can significantly increase the chances of survival for individuals experiencing sudden cardiac arrest. The effectiveness of a defibrillator system depends on rapid deployment and correct application.
