Development of an Implantable Oxygen Sensor:In Vivo Validation and Refinement.

摘要

Sensors for continuous measurement of oxygen tension in blood,tissue and endotracheal tubes are described. These sensors are fuel cells operating in the oxygen-diffusion-limited mode. The short circuit currents of these sensors are directly proportional to the oxygen tension of the surrounding medium. The basic principle of operation,sensor construction,and results of in vitro and in vivo studies are presented in great detail. Test results obtained to date show that these sensors are accurate,stable,fast responding and calibratible with only one PO2measurement.
