How to assess tissue oxygenation – A review of assessment techniques in critically ill patients () Daniel De Backer

Description

This review discusses various techniques used to assess tissue oxygenation in critically ill patients. It highlights the limitations of historical measurements (VO2/DO2, PO2) and emphasizes the utility of surrogate measurements like lactate, venous O2 saturation, and the promising application of veno-arterial PCO2 gradients to detect impaired tissue perfusion and dysoxia.
