Abstract

Does mixed venous oxygen saturation (\(S\bar v{O_2}\)O2) yield better information on the cardiorespiratory situation of the patient than the parameters usually measured: heart rate, systemic arterial pressure, cardiac filling pressures and cardiac output? From a theoretical point of view it should, and this was already pointed out more than 100 years ago in 1872 by the German physiologist Pflüger, who was the first to realize that the task of the cardiorespiratory sytem is to provide the organism with oxygen and substrates and to remove the waste products [11]. He stated that it is the oxygen needs of tissue cells that govern and regulate the whole system and that “arterial oxygen content, arterial pressures, velocity of blood stream, mode of cardiac work and mode of respiration all are incidental and subordinate, they all combine their actions in service to the cells.”
