WebMar 8, 2024 · Venous blood gases can provide information on acid-base status and ventilation (i.e., venous partial pressure of CO2 (Pvco2)).3,4 In adequately perfused patients, the Pvco2 is normally 4 to 6 mm Hg higher than the arterial partial pressure of CO2 (Paco2); the difference can be greater in severely hypoperfused patients.5 WebOct 2, 2024 · (1) PaO2 will be extremely high (typically >>100 mm), because the patient is being “treated” with high levels of supplemental oxygen. This immediately excludes true hypoxemia. (2) There is an obvious mis-match between the PaO2 (which is >>100 mm) versus the pulse oximetry (which is typically ~80-90% saturated).
