An Oxygen Sensitive Fuel Cell for Monitoring Blood Oxygen Tension during Total Body Perfusion

Abstract

A membrane-covered silver-lead fuel cell is desceibed which gives an output voltage proportional to the oxygen partial pressure in the environment to which the membrane is exposed. The device produces a constant output voltage in the temperature range 10° to 40° C when used in conjunction with a temperature compensation circuit. The fuel cell is used to monitor continuously the arterial oxygen partial pressure during whole body perfusion.
