WebApr 28, 2024 · pO2: This is measured by a pO2 electrode. It is the partial pressure (tension) of oxygen in a gas phase in equilibrium with blood. High or low values indicate blood hyperoxia or hypoxia, respectively. pO2 in venous blood is lower than arterial blood due to oxygen extraction by peripheral tissues. WebApr 28, 2010 · PaO2 is dependent on alveolar oxygen (PAO2), which is influenced by the FiO2, barometric pressure (high altitude), PaCO2 increase (respiratory depression), and the gradient between alveolar and arterial oxygen tension, which can be increased by ventilation and perfusion mismatch.
