In diabetic ketoacidosis, which pattern of breathing is characteristic?

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

Answer: (B)

In diabetic ketoacidosis the body faces metabolic acidosis from ketone buildup, so the respiratory system compensates by blowing off CO2. This produces Kussmaul breathing: deep, labored, and usually rapid breaths with a regular rhythm and increased tidal volume. It’s the body’s way of lowering acidity by reducing CO2. This pattern helps distinguish it from other abnormal breathing patterns: Cheyne-Stokes shows cyclical waxing and waning with periods of apnea; Biot respiration is irregular with clusters of breaths followed by apnea; Bradypnea is simply abnormally slow breathing. Recognizing the deep, slow-to-rapid, regular but labored breathing points you to metabolic acidosis with compensatory respiratory drive in DKA.
