Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called:

• A. Cheyne-Stokes respirations
• B. Biot respirations
• C. Kussmaul respirations
• D. Apneustic breathing

Answer: (A)

The pattern being tested is Cheyne-Stokes respirations: a cyclical rise and fall in breathing depth and rate, gradually increasing to a peak, then waning to a period of apnea before the next cycle begins. This waxing and waning with pauses reflects a disruption of the brain’s normal respiratory drive and is often seen in serious conditions such as advanced heart failure, stroke, or other central nervous system injuries. Understanding the others helps confirm why this is the best match. Biot respirations are irregular with chunks of breaths of varying depth followed by short periods of apnea, but they lack the predictable crescendo-decrescendo pattern. Kussmaul respirations are normal-in-shape in rhythm but are unusually deep and labored and occur with metabolic acidosis, not with alternating apnea. Apneustic breathing features a prolonged inspiratory pause, not the characteristic repeated cycles of increasing then decreasing effort with pauses. Recognizing Cheyne-Stokes breathing alerts you to possible serious cardiopulmonary or neurologic issues, guiding careful monitoring, airway management, and rapid transport as needed.
