What the rationale for taking body temperature before doing ABG analysis?

Answer 1

ABG (Arterial Blood Gases) is a measurement of oxygen saturation in the arterial blood which supplies oxygenated blood to the body tissue and the extraction of oxygen from the hemoglobin at the capillary level. The amount of oxygen saturation of the hemoglobin (HbO2) depends on hemoglobin concentration and the arterial pressure often referred to as Hemoglobin / O2 dissociation curve. At lower body temperature, less oxygen is bounded to hemoglobin, while at higher temperature slightly more oxygen is bounded to hemoglobin. It is therefore important to know the body temperature when the ABG analysis is done so as to have a more meaningful interpretation of the result.
