Monitors, Physiologic, Neurology, Electromyography, Bedside
Definition : Neurological bedside physiological monitors designed to continuously measure and display the intrinsic electrical potentials generated by muscle fibers. These units are hard-wired to the patient at the bedside. These monitors typically include electrodes (e.g., Nichrome wires) that are inserted into the muscles using a hypodermic needle; an electronic unit with an amplifier that boosts and transmits the bioelectric potentials; and a display that shows the action potential waveform. Electromyographic bedside neurological monitors can be used to display the electric potentials from a single muscle (e.g., extraocular, facial, laryngeal, lingual) or from several muscles simultaneously.
