The discovery that someone's heart can be restarted with the use of an electric charge is one of the greatest developments in modern medicine. This idea began around 1888 when William Mac suggested that ventricular fibrillation can cause sudden death. In 1989, Prevost and Batelli made the discovery that large amounts of voltage supplied to the cardiac ventricular fibrillation in animals could stop. Other studies funded by the nineteenth century, scientists have concludedCurrent effects on the heart.
An AED (Automated External Defibrillator) is a portable electronic device that is able to determine someone's heart rhythm. Detect life threatening problems within the heart and has the ability to treat them with defibrillation. If necessary, an AED can deliver an electric shock to the heart to restore a normal heart rhythm. When someone suffers a sudden cardiac arrest, the probability of survival he or she reduced 7-10 percentevery minute that passes without CPR or defibrillation or.
The first successful defibrillation of a human being was reported in 1947 by Dr. Claude Beck. During one of his operations, he realized his patients experienced ventricular fibrillation. He runs an AC of 60 Hz and stabilize the heartbeat. This particular patient was in his life, the defibrillators have been created.
An AED is equipped with a computer which evaluates heart rhythm, determines if it needsDefibrillation, and then manages the necessary degree of shock. The user of the AED is performed through this process with voice prompts, visual or both calls. Automated external defibrillators are usually in kits, power supply, electrodes including paddles and accessories sold. Each piece is made individually and then together with an integrated process. Today, manufacturers of medical devices, many defibrillators, external and internal, that created the situation for yearsthe lives of many patients.
External defibrillators used in hospitals and emergency sites. The user begins by turning on the defibrillator, and applying conductive gel to the patient's chest electrodes or paddle. The energy level is then chosen and the allegations of the device. The blades are mounted firmly on the chest with a slight pressure. To find the buttons at the electrodes are pressed together and then electric shock administered to the patient. After this procedure, theThe heart rate is then monitored for a regular heart rhythm. The entire process is repeated, if necessary.
In 1954 the first closed chest defibrillation in a dog Kouwenhoven and William Milnor was performed. This process was developed by Paul Zoll in 1956, studied the first success of a man. Qilliam Bennett Kouwenhoven was born in Brooklyn in 1886, was an electrical engineer, invented and developed, and three defibrillator and CPR techniques.
L '(AED Automated ExternalDefibrillator) was created 1978 Each unit is equipped with sensors that are placed on the chest to decide is, ventricular fibrillation occurs done. If it is established, the device provides the correct instructions for the supply of electric shock. These automated devices have the training that is necessary is to use defibrillators to reduce and also saved thousands of lives.
