Telemetry in health care.

This article reviews the use of telemetry in health care. Monitoring of biological signals of medical importance such as the EKG, EEG, and EOG are described. Employment of telemetry in critical medical and surgical environs such as the delivery and operating suites is covered. The enormous importance of telemetry compatible with public communication systems such as voice grade telephone lines for remote medical care is discussed. The article does not enter into strictly engineering systems aspects in any detail; this was not the intent of the author. Nor is there any pretence to a completeness obviously not possible within its confines. It does concentrate on radio (wireless) telemetry transmissions over relatively great distances with freedom of patient movement.
