The ventilatory response in uncomplicated diabetic ketoacidosis.

The ventilatory response to uncomplicated sub-acute metabolic acidosis was studied by measuring arterial blood CO2 tension (PaCO2) and pH in 27 episodes of diabetic ketoacidosis without coexisting lactic acidosis. From those data, regression equations and 95% confidence bands were calculated for the relations between PaCO2 and pH. These relations were very similar to those previously described by others in patients with chronic uremic acidosis.
