Abstract:
A polarographic oxygen sensor in contact with the palpebral conjunctiva makes a measurement of oxygen tension related to that in the underlying capillary bed but not equal to it. A mathematical analysis based on the equation describing oxygen diffusion in an oxygen-consuming tissue indicates that the measured oxygen tension will be 5-10 torr below that in the capillary bed.
