Splet- Central (ScvO2) is normally slightly lower than mixed (SvO2) due to high metabolic rate of cerebrum BUT is often higher than SvO2 in patients in shock Circulation is redistributed to cranial body at expense of splanchnic and renal circulation --> decreased DO2 to caudal body and therefore decreased pvO2 returning from caudal body --> SvO2 < ScvO2 Spletoxygen delivery (DO2), so that a low SVO2 is an important signal in patients who are hemodynamically unstable.
