Physiologic monitors designed for continuous measurement and display at a central station of information of the electrical activity of the brain and its associated electroencephalogram (EEG) taken from a distant location through a point-to-point radio or other appropriate communication link (i.e., telemetric) . Telemetric EEG monitors typically consist of a small electronic unit connected by several lead wires attached to brain electrodes that are usually placed on the patient\'s scalp. They include a pocket-sized, battery-powered transmitter that is clipped to the patient\'s gown or carried in a pouch and a receiver that is integral or associated to the central station where the information is displayed. Telemetric electroencephalography monitors are used in ambulatory, neurologically affected patients; they are also used for assessing the pattern changes in the brain waves and the neurologic status of patients in intensive care units.
