Which respiration pattern is commonly seen in diabetic ketoacidosis but not in Hyperosmolar Hyperglycemic State?

• A. Kussmaul respiration
• B. Bradypnea
• C. Apneustic breathing
• D. Cheyne-Stokes respiration

Answer: (A)

Metabolic acidosis drives the body to breathe harder and deeper to blow off carbon dioxide, raising blood pH. In diabetic ketoacidosis, accumulation of ketoacids lowers the pH, so the body mounts a marked compensatory response known as Kussmaul respiration — deep, rapid, steady breaths with no pause. This pattern is the classic sign of metabolic acidosis from DKA and is not typical for Hyperosmolar Hyperglycemic State, which usually has little or no ketoacidosis and therefore lacks this strong ventilatory drive. The other patterns come from different neurologic or cardiopulmonary conditions and don’t reflect the acid-base disturbance seen in DKA.
