WebVenous admixture occurs when blood equilibrates with an alveolar PO 2 that is less than ideal as in situations of low V/Q [3, 4]. Because venous admixture is not true shunt, this sometimes leads to confusion. The sum of anatomic and capillary shunts is most commonly termed zero V/Q or true shunt. ...

WebObjective: To determine whether the difference between oxygen consumption (VO2) measured by metabolic gas monitoring systems and by the Fick principle is related to venous admixture, deadspace/tidal volume ratio, or alveolar-arterial oxygen tension gradient in critically ill patients.
