The normal range of SvO2 and ScvO2 is 70-75%. Remember that these values are dependent on two main components, oxygen delivery (DO2) and oxygen consumption (VO2). Generally speaking, the normal ScvO2 and SvO2 is above 70%. This is more pronounced in shock states. There is also some data where this is shown to be the opposite. ScvO2 is generally 5-6% higher (sometimes more) as this blood comes from the brain and upper extremities which generally consume less O2 than the organs and lower extremities. – it’s easy to confuse the two because the PA is more “central” but think about it as getting this value from the “central line” Correlation between ScvO2 & SvO2

That central line could be placed in the internal jugular, subclavian, or axillary vein.

– taken from a central line that terminates in the Superior Vena Cava or right atrium. – The meaning of ScvO2 is central venous oxygen saturation – this is a combination of venous oxygen from both the SVC and IVC ScvO2 – also called a mixed venous oxygen saturation. Given then tools normally found in the ICU, one cannot measure this value without these catheters. – taken from a Swan Ganz catheter also called a PA or pulmonary artery catheter. – The meaning of SvO2 is venous oxygen saturation

I am not going to get into the deep dive complexities of venous oxygen levels as that could be a complete chapter in a textbook but feel free to ask questions below and either I or our community will try to answer the questions. Or perhaps you don’t know that you don’t know this. ScVO2, it all comes down to the catheter type. If you have to determine whether you’re going to measure SvO2 vs. Regardless of whether you’re a nurse, respiratory therapist, medical student, resident, or even a fellow, these terms may sometimes be quite confusing as everyone talks about them like, “duh, you’re supposed to know this”. You’ve heard all these fancy terms, mixed venous blood gas, ScvO2, SvO2, thrown around the ICU all the time.
