Blood gas measures pH, PCO2, and oxygen (O2), and all the other components (base excess, bicarbonate concentration, and oxygen saturation) are calculated based on the 3 levels measured. Accepted normal values for an arterial blood gas on room air are pH 7.35 to 7.45 (pH varies with age; a pH >7.30 is generally acceptable), PaCO2 35 to 45 mm Hg (slightly higher accepted if the blood pH remains normal), and PaO2 50 to 95 mm Hg (based on gestational age). (See Table 9–1, for normal range of arterial blood gas values for term and preterm infants.)
