You Will Be Shocked
Defibrillator is being charged, back off. 3 joules. I withdrew, you too, withdraw everyone. I'm giving shock. Again. 5 joules. I withdrew, you too, withdraw, everyone should. I'm giving shock. The patient came back. And the applause sounds !!! It's almost a dialogue we hear in every action movie. But in real life, a complete tragedy is a life and death war.
Defibrillation is called a procedure performed by a special electrical device to eliminate the irregular vibrations in the heart muscle by giving current to the heart and to ensure the normal functioning of the heart, and this process is performed with a device called defibrillator. Defibrillator is a device that gives a short-term high value current to the heart in order to restore the normal rhythm of a fibrillated heart. In short, we all know as an electro shock device.
In 1850, Karl Ludwig directly electrified the heart of a dog and achieved fibrillation. In 1899, Batelli and Prevost found that weak flow caused ventricular fibrillation (VF) and strong flow stopped VF. In 1933, Kouwenhoven applied internal defibrillators to dogs. In 1947 Claude Beck developed the Defibrillator and saved a person with defibrillation. 1956, Paul Zoll used the first alternating current (AC) defibrillator in a syncope patient. In 1960, Bernard Lown introduced the first direct current (DC) defibrillator. In 1965, J. Frank Pantridge placed a portable defibrillator inside the ambulance for pre-hospital use. Automatic External Defibrilator (OED) in 1979: The idea was made that the first OEDs can be used in the pre-hospital setting. In the early 1990s, biphasic defibrillation was introduced.
Parts of the defibrillator; power supply, electrical circuit board, sensors, monitor, printer and electrode. The defibrillator is made of plastic. The power supply is the section that stores electrical energy as chemical energy and, when desired, gives it as electrical energy. Even if the defibrillators are plugged into the mains, they will run on battery, so the battery must always be charged. The monitor has an LCD screen feature that allows the electrical activity of the heart to be monitored. The device detects the electrical activity of the heart with defibrillator electrodes or ECG patient cable. Also PO2 shows the applied joules, etc. The printer (recording unit) automatically records after each defibrillation, the amount of energy applied, date, time, etc. is the section that records the information. It is memory and provides ECG. If ECG electrodes are also attached, ECG recording can be obtained in different leads. There are two conductive electrodes used to transmit electrical energy to the patient by discharging the electrodes capacitor. Types of defibrillator electrodes:
• A spoon-shaped electrode: It is applied directly to the heart.
• Paddle type electrode: Applied on the chest wall.
• Pad type electrode: It is applied by sticking on the chest wall.
• ECG electrodes
Thanks to the defibrillator, 30,000 lives are saved annually in the UK.
