High pvo2
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. WebI have been always told that the venous (mixed venous of Central venous) PO2 does not go above 40, even if the arterial PO2 is elevated to very high levels (say 150) by increasing the FiO2 in...

WebThe cut-off value of VE/VCO2 slope showed lower values of PPV (33.3%) and similar NPV (92.3%) to pVO2 results in the AF group. Conclusion: Despite the fact that AF carries a worse prognosis for HF patients, the current cut-off of pVO2 for HT selection can precisely stratify this high-risk group.
