Abstract

The proposed application of this work is to the measurement of both tissue perfusion and tissue p02 with the same Polarographic probe. It is anticipated that membrane characteristics will markedly affect the overall flow sensitivity or insensitivity of a particular probe when operated under pulsed conditions. Moreover operation with very short pulse times requires consideration of the rapid development of the “double layer” as the double layer current can be significantly larger than the current due to the Polarographic reaction. The effect of the double layer formation is specifically considered below along with the incorporation of convective phenomena in the model.
