title: A 4-channel telemetry system for hospital patient monitoring.
abstract: A 4-channel radio telemetry system has been designed and implemented for use in the operating room on patients undergoing surgery. 30 such systems are in daily use throughout the Duke University Medical Cener. Relative simplicity, long battery life and a DC-response capability are the important features of these systems. The four physiological channels used are; electroencephalogram, electrocardiogram, peripheral pulse, and arterial blood pressure.
