What is Defibrillator? How does it work?

Collaborative Post

A defibrillator or AED is a gadget that restores an average heart rate by giving an electric pulse or shock to the heart. They are used to correct an arrhythmia, a heartbeat that is irregular or too slow or too fast. In addition, it restores the heart’s beating if the heart suddenly stops.

Different sorts of defibrillators work in different ways to save a patient’s life. Automated external defibrillators, also known as AEDs, were developed to save the lives of people undergoing sudden cardiac arrest (SCA). Anyone can use these devices in an emergency.

Why is Defibrillator Important?

In critical situations like a heart attack or uneven beating, which involves an SCA, early defibrillation is the most vital link. Since defibrillation is the most helpful treatment for cardiac arrest, the more a patient has to wait for a defibrillation shock, the less the chances of survival.

Although doctors and scientists say that CPR can increase the neurological viability in VF for around ten minutes using chest compressions. CPR alone cannot revive a regular rhythm, and defibrillation is a must to regain heart function.

How Automated External Defibrillators work?

Automated External Defibrillators (AEDs) are small, portable defibrillators designed mainly for out-of-hospital settings. They are often put in public places such as airports, malls, swimming pools, police cruisers, and homes for both workers and trained people and Emergency Medical Services.

Different AEDs have differing functionalities. Starting from pure shock-inducing AEDs, semi-automatic types, to fully automated technique that automatically monitors the heart rhythm and automatically sends the shock-pulse if needed.

Who can use AED?

Generally, the defibrillation depends on how fast EMS staff can get to the scene of an emergency and use their latest equipment. With an AED, though, first responders such as police, firefighters and other officers, or even briefly trained bystanders and family members can rapidly strike defibrillation and thus improve the patient’s prognosis.

Aside from their simplicity, AEDs are designed with safety in mind so that even errors in an appeal do not harm the patient or person initiating the shock.

Improving the number of openly available AEDs has been one of the references/requirements many health professionals in the industrialized world have instituted. In many regions where AEDs have been made public, there has been a helpful reduction in the time-to-defibrillation and developed SCA survival rates.

More rapid response times are related to a more prominent possibility of SCA durability, making AEDs crucial in remote or crowdie areas where EMS response times are slower. Upon that, various studies have discovered a correlation between survival rates from SCA and the utility of AEDs. Medical specialists suggest that defibrillation be attempted as quickly as possible after the onset of cardiac arrest cause survival from VF is defined primarily by the time-to-defibrillation.

The defibrillators can stop sudden death amongst people who have a high risk of arrhythmia. They add implantable cardioverter defibrillators (ICDs) that can surgically place inside patients’ body. Also, wearable cardioverter defibrillators (WCDs) which can rest on the body.
