Review[Management of oxygen delivery and consumption during sepsis].
Maintaining an adequate tissue oxygen delivery (DO(2)) and consumption (VO(2)) is crucial in the treatment of septic patients. A fall in V0(2) is associated with a higher mortality. The early recognition of shock or tissue hypo perfusion impacts on patient prognosis. ⋯ However, interpretation of these markers should be cautious and always considering the overall clinical status of the patient. In the initial stages of sepsis, the dependency of V0(2) on DO(2) predominates as histopathological mechanism of multiple organic failure. In late stages, other factors predominate as determinants of multiple organic failure and mortality, such as hyper or hypo immune response, microcirculatory alterations and cytopathic hypoxia.
