Oxygen Transport Following Major Trauma

  • J. D. Edwards
Part of the Update in Intensive Care and Emergency Medicine book series (UICM, volume 5)


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)
