AED Defibrillators – Basic Overview Of The Mechanism

Oct 1st 2015 at 6:23 AM

The human heart is a complex machine that works to keep your body alive and moving. The importance of this integral component in your system cannot ever be over-emphasized. It contains special pacemaker cells that generate electrical impulses responsible for powering this organ. And these cells are some of the most delicate mechanisms in the human body, capable of being effected by various external stimuli including medication, stress, and physical activity, just a few things that change body chemistry; altering chemical impulses, increasing or decrease heartbeat.

These external stimuli often render these special pacemaker cells to become less and less effective. Any malfunction in this system will cause your circulatory system to falter and your heart to fail. External Defibrillation is medical science’s solution to prevent such a problem. Defibrillation is the administration of a jolt of electricity to the heart which depolarizes the heart muscle and allows the heart's natural pacemaker to potentially reset and continue beating. This becomes possible through AED Defibrillators.

These medical devices may be considered to be similar to what you may have seen on a television drama series where a patient’s failing heart is jolted back to life using AED Defibrillators. These machines are available in different configurations and with different abilities. The situation that is depicted in TV shows however is slightly outdated. Modern day defibrillators have been made to be completely automatic. They typically have Prophylactic nodes, which are attached to the chest of the patient and also used to monitor heart rate. These nodes deliver shocks when a shockable heart rhythm occurs.

Most hospitals these days use partially or fully automatic defibrillators to provide patients with constant care. The more popular brands in this product category are Cardiac Science, Zoll, Phillips HeartStart, and Samaritan. These devices have been designed to provide adequate information to doctors in hectic hospital environments. Most models feature a text screen that runs in conjunction with voice prompts, which are capable of conveying data in chaotic and often noisy hospital settings. The device displays the patient's heart rate, the waveform, number of shocks delivered, and the elapsed time. They usually have built in systems for pacemaker pulse detection and synchronization systems, along with visual cues to guide rescuers in making the right calls.

AED Defibrillators are some of the most important medical machines that are used by hospitals all over the world. They help in monitoring patient heartbeats and can automatically provide the stimulus necessary to jumpstart a heart in case cardiac arrest occurs. These devices have also been designed for use in residential settings in case a patient chooses to not live and recuperate in a hospital. They are easy to use and do not always need professional handling. This machine is singlehandedly responsible for a significant reduction in the number of deaths caused as a result of cardiac arrest when doctors were a little too late to arrive at the scene and restart a patient’s heart.
