You've heard all these fancy terms, mixed venous blood gas, ScvO2, SvO2, thrown around the ICU all the time. 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're here because you don't know this. Or perhaps you don't know that you don't know this. Or perhaps you need a refresher course. 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. • SvO2: • venous oxygen saturation • taken from a Swan Ganz catheter. without a PA catheter, you can't measure this • also called a mixed venous oxygen saturation. • this is a combination of venous oxygen from both the SVC and IVC • ScvO2 • stands for central venous oxygen saturation • taken from a central line that terminates in the SVC or right atrium. Could be an internal jugular, subclavian, or axillary line. • 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 • 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. This is more pronounced in shock states. • I'll dig deeper into this in the near future. The article where these images were taken from is FREE!
