What does an AED do?

An AED, or automated external defibrillator, is used to help those experiencing sudden cardiac arrest. It’s a sophisticated, yet easy-to-use, medical device that can analyze the heart’s rhythm and, if necessary, deliver an electrical shock, or defibrillation, to help the heart re-establish an effective rhythm.

Which intervention is FDA approved for lay rescuer use?

Zoll Medical announced yesterday that its Zoll AED 3 defibrillator received FDA premarket approval (PMA) for use by lay rescuers.

Does AED stop heart?

This shock depolarizes the heart muscle and eliminates the fatal arrythmia by completely stopping the heart altogether.

What are the different types of defibrillators?

There are three types of defibrillators: AEDs, ICDs, and WCDs. Learn more about your heart’s electrical system at How the Heart Works.

Do you do CPR before AED?

Always call 911 first before administering CPR or using an AED. The timing of the use of an AED first depends on how accessible an AED is. If an AED is immediately accessible, get the AED and use it right away. However, in all likelihood, there will not be an AED close enough and CPR should be started first.

Can you use AED without CPR?

The fastest way to treat a child or baby in sudden cardiac arrest, SCA, is to perform successful CPR and use external defibrillators, AEDs. The condition could be life-threatening in minutes without adequate CPR and the use of an AED device to restart or restore the heart and its normal heart rhythm.

How is VF treated?

External electrical defibrillation remains the most successful treatment for ventricular fibrillation (VF). A shock is delivered to the heart to uniformly and simultaneously depolarize a critical mass of the excitable myocardium.

Who is responsible for a defibrillator?

Every defibrillator should have a ‘Guardian’. This is someone who is responsible for carrying out regular checks on the device and cabinet if applicable. A defibrillator guardian ensures the defibrillator remains in a ready to rescue state at all times and acts on any problems to do with the device and its consumables.

Can you use an AED with no heartbeat?

No. Other abnormal rhythms like a very slow heart rate or no heartbeat at all, can’t be treated with an AED. When a user puts the AED’s electrodes or adhesive pads on a victim’s chest, the device determines whether the patient’s heart needs to be shocked or not.

Can an AED restart a heart?

The AED measures the collapsed person’s heartbeat to find out whether he or she has what we call a “shockable” rhythm — a heartbeat that the AED can reset. If the person has a shockable rhythm, the AED delivers an electrical shock across the person’s chest to reset the heart rhythm.

Is VF life threatening?

Ventricular fibrillation is a type of arrhythmia, or irregular heartbeat, that affects your heart’s ventricles. Ventricular fibrillation is life-threatening and requires immediate medical attention.

What VF feels like?

Warning signs and symptoms Very fast heartbeat (tachycardia) Dizziness. Nausea. Shortness of breath.
