What is a normal CvO2?

What are the normal values? Normal SvO2 60-80%. Normal ScvO2 (from an internal jugular or subclavian vein) is > 70%.

What are normal SvO2 levels?

The normal SvO2 ranges between 60-80%. If SvO2decreases, it indicates that the tissues are extracting a higher percentage of oxygen from the blood than normal. In otherwords, a decreased SvO2 indicates that the cardiac output is not high enough to meet tissue oxygen needs.

What does the venous content CvO2 represent?

The main overall parameters of mixed-venous oxygen status are oxygen content (cvO2), cardiac output (C.O.), and oxygen consumption (QO2) of the tissues.

What is SvO2 and PvO2?

Abstract. Mixed venous oxygen saturation of hemoglobin (SvO2) and mixed venous oxygen tension (PvO2) may reflect the overall balance between oxygen consumption and delivery.

What is CaO2 and CvO2?

CaO2 = arterial Oxygen Content (mL/dL) CvO2 = mixed venous Oxygen Content (mL/dL)

Is SvO2 or ScvO2 higher?

ScvO2 only measures venous blood returning from the upper half of the body, while SvO2 samples the true mixed venous blood leaving the right heart. Central (ScvO2) is normally slightly lower than mixed (SvO2), but is often higher than SvO2 in patients in shock.

What is high PvO2?

Partial pressure of oxygen in arterial blood (PaO2) is “usually normal or low-normal in cases of CO poisoning but partial pressure of oxygen in venous blood (PvO2) is abnormally high, indicating substantial impairment of oxygen delivery from arterial blood plasma into tissue,” Donnay explains.

What is normal CaO2?

Normal CaO2 ranges from 16 to 22 ml O2/dl. Because PaO2 and/or SaO2 can be normal in certain conditions associated with hypoxemia, one should always make sure CaO2 is adequate when assessing oxygenation.

What is SvO2 in cardiogenic shock?

SvO2 = mixed venous oxygen saturation. measured via a sample of blood from a pulmonary artery catheter (PAC) measures the end result of O2 consumption and delivery.
