Metabolic Medicine Made Simple : Mixed Metabolic and Respiratory Acidosis

pH would be below 7.35.

HCO3- would be reduced suggestive of Metabolic Acidosis.

PaCO2 would be reaised or inapprprately normal.

Winter formula is used to calculate what PaCO2 ought to be in order to compensate for the metabolic acidosis and that PaCO2 is inappropriately normal.

Winter formula is as follows :

PaCO2 = 1.5 (HCO3-) + 8
