Hemodynamic aspects of multiple organ failure

Abstract

Multiple organ failure (MOF) secondary to sepsis is associated with a high mortality. A large body of evidence suggests that the disturbed relationship between oxygen supply and oxygen uptake plays an important role in the pathogenesis of MOF. The relationship between oxygen-supply dependency and MOF and the practical implications of the relationship are reviewed. It is concluded that, apart from the all-important eradication of the source of the sepsis, optimizing oxygen transport is the best method of preventing the development of MOF. Since the effects of hemodynamic and ventilatory treatments on oxygen uptake are often unpredictable, the impact of the treatments on oxygen uptake should be evaluated directly.
