Hypoxemia due to increased venous admixture: influence of cardiac output on oxygenation

  • Jukka Takala
Chapter

Abstract

In the hypoxemic patient under mechanical ventilation, changes in cardiac output may influence the level of arterial oxygenation, with several and sometimes opposite effects. The purpose of this Physiological Note is to give the reader the physiological background to understand these effects, which are often highly relevant for the bedside management of patients with acute lung injury.
