Abstract

A simple device is presented to monitor periods of apnea without the use of electrodes. Conductive rubber tubing which changes its electrical resistance with change in length was incorporated into a belt and attached to an apnea monitor. Thus, the high-frequency current from the apnea monitor flows through the conductive rubber sensor instead of through the patient. This technique eliminates the need for electrodes and electrode paste, makes attachment and removal of the sensor simple, and further improves electrical safety by removing the patient from any direct current pathway to the apnea monitor. The device was experimentally used with a telemetry system.
