defibrillointilaitteet

Defibrillointilaitteet, commonly known as defibrillators, are medical devices used to deliver an electrical shock to the heart. This shock is intended to interrupt an abnormally fast or irregular heart rhythm, such as ventricular fibrillation or pulseless ventricular tachycardia, and allow the heart to resume a normal rhythm. These devices are crucial in the emergency treatment of sudden cardiac arrest, a condition where the heart abruptly stops beating effectively.

There are two main types of defibrillators: manual and automated external defibrillators (AEDs). Manual defibrillators are typically used by trained medical professionals in hospitals or ambulances. They require the operator to interpret the heart rhythm and decide when and how to deliver the shock. AEDs, on the other hand, are designed for use by laypeople with minimal training. They are equipped with sensors that analyze the patient's heart rhythm and guide the user through the process, automatically advising whether a shock is needed and delivering it if necessary.

AEDs are increasingly found in public places such as airports, shopping malls, and sports facilities, significantly increasing the chances of survival for individuals experiencing cardiac arrest outside of a hospital setting. Early defibrillation, combined with cardiopulmonary resuscitation (CPR), is a critical factor in improving outcomes for sudden cardiac arrest victims. The devices work by delivering a controlled electrical current through the chest wall to the heart, resetting its electrical activity.
