How does a defibrillator work?
When an individual goes into cardiac arrest, their heart goes into fibrillation which is somewhat a quivering limbo. Most of the time, especially when it occurs suddenly, cardiac arrest can lead to the death of the Individual. At other times, however, it is possible for an individual to survive cardiac arrest even though chances are slim. Also, there are ways in which to revive the heart activities in the event that you fall into cardiac arrest. Among the most efficient ways to get your heart going when suffering an arrest is to introduce a sudden powerful electric shock. This is what a defibrillator does. In the past, the equipment required immense training. However, in the contemporary world, they are fully automatic and do not necessarily require you to be proficient in the operation. Most of the automatic defibrillators are being installed in most public places to aid in reviving a patient who falls into cardiac arrest in public. Below is a closer look at how these gadgets work.
What happens in the event of a cardiac arrest?
Your body is a network of muscles which perform various important functions. One of the most critical and powerful muscles is the blood pump in your heart. This muscle works throughout your life right from birth to your last breath. The moment your heart stops beating in the manner that it should be, the brain does not get enough oxygen supply, and you can die in a very short time. This is the sole reason why individuals who suffer cardiac arrest need emergency medical attention cardiopulmonary resuscitation is critical in helping to maintain the flow of oxygen to the brain. However, restarting the activity of the heart would require defibrillation.
What is a defibrillator?
As the name goes, a defibrillator primarily stops fibrillation. Fibrillation is the trembling that an individual’s heart adopts in the event of cardiac arrest. In essence, a defibrillator uses high voltage to pass an electric shock through the heart muscles so that it is shocked and starts performing in a normal way. The heart of the patient receives about 300 joules of electrical energy.
Common defibrillators are made up of an electric supply unit alongside two metal electrodes known as paddles. The paddles are pressed firmly to the chest of the patient. Since it releases shock, the person using it may also get shocked, and that’s why it has insulating plastic handles to take care of such problems. What’s crucial in this process is to get an electric current to flow through the heart, and that is why the site at which the paddles are applied is important. To use them, put one paddle above and to the left of the position of the heart while the other is to be positioned beneath and to the right. Another way of performing this procedure is to put one of the paddles on the front of the body and the other around the back. When doing this, it is very easy to burn the skin. To avoid this, the electrodes have to be put as close together as possible. Again, they should make excellent electrical contact with the skin. For this purpose, a liquid or solid gel is often applied to the chest of the patient to conduct electricity.
Using a defibrillator, especially an automatic one, is very easy thus making it extremely possible to avoid unnecessary deaths brought about by cardiac arrest.
