It is known that oxygen tension in tissue (ptO2) will change in response to an alteration of physiological parameters including: pCO2 in arterial blood, blood flow, capillary density, oxygen carrying capacity, and p50 of hemoglobin. We have used modeling to compute the change of ptO2 in response to changes of each physiological parameter and related these changes to experimental data. The oxygen...
We describe our results on the effect in rats of two commonly used, volatile anesthetics on cerebral tissue PO2 (PtO2) and other physiological parameters at FiO2 levels ranging from 0.35 to 0.1. The study was performed in 12 rats that had lithium phthalocyanine (LiPc) crystals implanted in the left cerebral cortex. FiO2 was maintained at 0.35 during surgical manipulation and baseline EPR measurements,...
The isolated heart, typically perfused with crystalloid media equilibrated with ≥95% O 2 to ensure adequate myocardial oxygen tension, is commonly used to study cardiac function. When hemoglobin is available for oxygen transport, equilibration with 21% O 2 is considered adequate to meet metabolic demands. This study presents the measurement of myocardial pO 2 in isolated hearts...
