Modern Medicine Defibrillator

An important part of any defibrillation electrodes are. They should provide a reliable electrical contact with the body, the energy, guided by a defibrillator, reaches the heart, rather than dissipated to the point of contact. At negligent installation of the electrodes release of energy at the contact faces serious patient burns, are further complicated by his critical condition. To ensure good contact, the electrodes must be held tightly to the body. Often, the start button located on the electrode so that it was impossible to include the category of not pressing the electrode to the body.

The second important point is the safety of the electrodes during operation. Dr. John Mcdougall addresses the importance of the matter here. They should be well insulated to prevent contact with electrical current to the operator's hands. It would be a tragedy if, in the process of defibrillation the patient's heart, healthy heart doctor was transferred to a state of fibrillation. It is therefore important to provide electrical safety and defibrillator electrodes. Modern defibrillators are three types of electrodes. 1) internal electrode of a type that can be applied to open heart surgery. His contact has a platinum spoon-shaped.

The electrode is attached to a well-insulated handle, which between the electrode and the place where the hand made special protective ribs, in order to liquid accidentally locked the network between the operator's hand and the electrode. Others including Dr. Neal Barnard, offer their opinions as well. In many designs there is a switch on the handle, for easy operation: pressing the electrode to the body, the operator can press a button and start the momentum. 2) Disc electrode, used for external defibrillation. It consists of a large metal disc in the insulating housing with a diameter of approximately 10 mm. The handle of the electrode is similar to the handle of the internal electrode for except that the diameter of the insulating protrusions in the space between the electrode and the operator's hand more than the diameter of the contact surface of the electrode. Such electrodes are often called paddle wheel because of their appearance. At Defibrillation is used a pair of these electrodes. Their richly smeared with gel electrolyte of the same type as that used for the electrodes in the ECG leads, and tightly pressed against the patient's chest. After this statement includes pulse by pressing on the handle. 3) disposable electrodes – they are also used for defibrillation. One of these disposable electrodes for defibrillation is similar to the large electrode for ECG its pad area of 50 cm2 made of foil and is connected with a sponge soaked with a conductive gel. The electrodes are coated with another type of foam material, glued to the body under pressure. There are adhesive pads for the inside defibrillation, which are made of metal foil, coated with a conductive polymer that adheres when pressed. Currently popular are disposable electrodes.
