Ratiometric analysis of arterial blood gas from index case

Parameter Patient Value Normal Value Ratio
pH 7.5 7.4 —
[H+] 31.62 nM 40 —
PCO2 93.7 mm Hg 40 2.34
[HCO3] 70.58 mM 24 2.94

Both metabolic and primary respiratory alkalosis are present. The greater ratio for plasma [HCO3–] is consistent with metabolic alkalosis as the dominant acid-base disorder. [H+], hydrogen ion concentration (nM); PCO2, carbon dioxide partial pressure (mm Hg); [HCO3–], bicarbonate concentration (mM).
