Maternal and Fetal Tissue PO2 in the Pregnant Ewe Measured with Galvanic PO2 Electrodes
A galvanic PO2 electrode is the basis of a glucose sensor designed by Bessman and Schultz (1) for the artificial pancreas. We have used this electrode as a direct PO2 sensor and have previously recorded our experience with implantation of electrodes in the rabbit for periods of seven to twenty-one days to determine tissue PO2 in the undisturbed state (2), and during the administration of epinephrine (3).
