Paper Abstract

It is well known that the relation between the partial pressure of oxygen in blood (PO2) and the hemoglobin oxygen saturation in blood (SO2) is given by the oxyhemoglobin dissociation curve. In this study, we investigate if a similar relation exists in tissue. The PO2 in tissue was approximated by the transcutaneous partial pressure of oxygen (TcPO2) measured by TCM3TM Transcutanous pO2/pCO2 Monitoring System; and the SO2 in tissue (StO2) was measured by ODISseyTM Tissue Oximeter. The study showed that the TcPO2 versus StO2 relation is similar to the dissociation curve in blood, as expected.
