Fully Automatic External Defibrillator

Fully automatic external defibrillator, which defines the rhythm and automatically delivers the shock independently from the operator when defibrillation is required. There is no “SHOCK” button on fully automated defibrillators, as the defibrillation procedure is applied by the device. There is no SHOCK button on fully automatic defibrillator but they are present on semi-automated defibrillator. In functional terms, fully automatic defirbrillatos are no different from semi-automatic defibrillators.

RitimPort Fully-Automatic Defibrillator is a lightweight and portable medical device that delivers electroshock (defibrillation) to the heart through the chest via pads. This shock stops the irregular cardiac contractions for a very short period of time, allowing the heart to return to its normal contractions. Sudden cardiac arrest leads to cardiac dysfunction. Unless the shock is delivered in a very short time period, this could lead to death. The most common form of sudden cardiac arrest is ventricular fibrillation, which is rapid and irregular cardiac rhythm. When ventricular fibrillation occurs, the heart should immediately be defibrillated, as the patient’s chance of survival decreases by 10% every minute.

Sudden Cardiac Arrest

Sudden Cardiac Arrest occurs suddenly and often without warning and sign. It is triggered by an electrical malfunction that causes an irregular heartbeat (arrhythmia) in the heart. When the pumping movement is impaired, the heart cannot pump blood to the brain, lungs and other organs. Seconds later, the human loses consciousness and the pulse disappears. If the patient is not treated in a short time, death occurs within minutes. This condition is called sudden cardiac arrest.

It results in main arteries and respiratory arrest and loss of consciousness. When circulation stops, the tissues do not reach oxygen. Since the brain is the organ most affected by the lack of oxygen, loss of consciousness and subsequent brain damage can lead to neurological deficits, memory disorders and cognitive dysfunction. According to the basic life support (BLS) principles, the first thing to do is to re-initiate circulation, ie cardiopulmonary resuscitation (CPR). According to the principles of advanced life support, the first thing to do in sequence is to monitor the patient and perform defibrillation.

The only proven treatment for patients with ventricular fibrillation and ventricular tachycardia during sudden cardiac arrest is the “defibrillation” procedure. Defibrillation is performed with automatic defibrillators or manual defibrillators.

Defibrillation

Defibrillation is simplest explanation; The aim of this study is to depolarise as many myocardial cells as possible and to give the heart an opportunity to form a regular rhythm for correction of ongoing rhythm disorder. Defibrillation is a technique used in emergency medicine to terminate ventricular fibrillation (VF) or pulseless ventricular tachycardia. Defibrillation is performed by a medical device called defibrillator device.

The defibrillation procedure is applied with an accessory called an electrode / paddle / pedal. Gel should be applied to the pedals being used. It is necessary to ensure that there is no gel connection between the paddles. Electrodes should be compressed by approximately 10 kg in adults, and 5 kg in children. As the electrode should be firmly attached to the chest wall, if the chest is excessively hairy, it should be shaved, unless doing so would lose too much time. Before pressing the discharge button, you should make sure that nobody is touching the patient. If there is a transdermal patch on the patient’s thorax, you should pay attention to ensure that it does not come into contact with the electrodes.
