Defibrillators are medical devices that deliver an electric shock to the heart to restore a normal heartbeat. There are two main types of defibrillators: external defibrillators and implantable defibrillators.
External defibrillators are designed to be used outside of a hospital setting. They can be found in public places like airports, shopping malls, and sports arenas. These defibrillators are usually operated by non-medical personnel and are designed to be easy to use. They come equipped with instructions and electrodes that can be placed on the chest to deliver a shock.
Implantable defibrillators are surgically implanted in the chest and are used to treat people at high risk of sudden cardiac arrest. These devices constantly monitor the heart rhythm and can deliver a shock if needed. They have advanced features like the ability to adjust shock levels and automatic monitoring and alerts. They are typically recommended for people who have already experienced a cardiac event or have a history of heart disease.
Overall, defibrillators play a critical role in saving lives during cardiac emergencies. They help to restore a regular heartbeat and can prevent further damage to the heart and brain.
