Electrodes In Defibrillators
If you are in need of medical supplies, there are many different medical equipment suppliers that you can find online. There are medical devices and laboratory equipment that is hard to find elsewhere. One of the best items of medical equipment that one can purchase ins the defibrillator. This piece of medical equipment can end up saving your life from your very core. The electrode is a key part of any defibrillation system. The proper selection and placement of electrodes can determine the effectiveness of the procedure. This is how it is displayed: a circuit diagram shows the simplest defibrillator design, depending on the inductor. The most well-known type of electrode is the traditional metal paddle with an insulated handle. This type must be held in place on the patient's skin while a shock or a series of shocks is delivered. Before the paddle is used, a gel must be applied to the patient's skin, in order to ensure a good connection and to minimize electrical resistance, also called chest impedance. When a patient has been admitted due to heart problems, and the physician or nurse has determined that he or she is at risk of arrhythmia, they may apply adhesive electrodes to the patient in anticipation of any problems that may arise. These electrodes are left connected to a defibrillator. If defibrillation is required, the machine is charged, and the shock is delivered, without any need to apply any gel or to retrieve and place any paddles. Both solid- and wet-gel adhesive electrodes are available. Solid-gel electrodes are more convenient, because there is no need to clean the patient's skin after removing the electrodes. However, the use of solid-gel electrodes presents a higher risk of burns during defibrillation, since wet-gel electrodes more evenly conduct electricity into the body. Adhesive electrodes are designed to be used not only for defibrillation, but also for non-invasive pacing and electrical cardioversion. While the paddles on a Monitor/Defibrillator may be quicker than using the patches, adhesive patches are superior due to their ability to provide appropriate EKG tracing without the artifact visible from human interference with the paddles. Many monitor defibrilators provide three, five or 12-lead EKG monitoring to compensate for this downfall of the paddles. Adhesive electrodes are also inherently safer than the paddles for the operator of the defibrillator to use, as they minimize the risk of the operator coming into physical contact with the patient as the shock is delivered, by allowing the operator to stand several feet away. Another inconvenience of the paddles is the requirement of around 25lbs of pressure to be applied while defibrillating. Upon placing the electrodes on the patient, the control computer in an advanced system will assess the patient, determining the type of rhythm or arrhythmia present. It will then set appropriate power levels and signal that a shock is needed. If the patient does not require defibrillation, units will not allow a shock to be administered. A button must still be depressed manually to trigger the shock, as the operator beforehand must be certain that no-one is touching the patient at that time. Often, AEDs will have speakers which give audible commands when the AED is opened. |
