Critically ill patients require intensive monitoring during their care, both to detect and access acute changes that might occur and to determine the response to a therapeutic intervention. Blood gas sampling, which includes both arterial and mixed venous blood, is a modality that provides important information on a patient’s metabolic status as well as their overall oxygenation (Table 3-1). Clinical decision making based on the analysis of the blood gas data often leads to changes in patient care, which may have a significant effect on their survival. This chapter discusses both arterial and mixed venous blood gas analysis and the implications.
