Abstract
The concepts of oxygen delivery (DO2) are now well established and measurement of related variables are routinely made in critically ill patients [1], not least because measurement and manipulation of these variables has been shown to predict [2] and improve [3] outcome. Therefore the physiology of DO2 will not be reviewed in detail in this chapter but the terms used will be defined at the onset:
-
CaO2 = arterial O2 content (ml/dl)
-
Cv̄O2 = mixed venous O2 content (ml/dl)
-
SaO2 = arterial oxyhemoglobin saturation (%)
-
Sv̄O2 = mixed venous oxyhemoglobin saturation (%)
-
CI = cardiac index (1/min/m2)
