Depending on the timing of patient presentation and the type of sepsis and septic shock, Svo(2) may indeed be elevated as a result of microcirculatory shunting or mitochondrial dysfunction. However, in septic shock, Svo(2) can be depressed, reflecting an increase in the extraction of oxygen due ...
