Which breathing pattern is described as shallower breaths with pauses and crescendo?

• A. Kussmaul respirations
• B. Apneustic breathing
• C. Central neurogenic hyperventilation
• D. Cheyne-Stokes Respirations

Answer: (D)

This item is testing your ability to recognize a cyclic pattern of breathing that waxes and wanes in volume with pauses in between. The described sequence—breaths that crescendo to a peak, then decrescendo, followed by a brief pause—fits Cheyne-Stokes respiration. It creates periods of shallow or absent breathing (apnea) between cycles and tends to repeat, a pattern often seen with impaired cerebral perfusion or central control of respiration, such as in advanced heart failure, stroke, or brain injury. Other patterns don’t match this cycle. Kussmaul breathing involves deep, rapid breaths without the distinct waxing and waning or pauses. Apneustic breathing features prolonged inspiratory pauses rather than a crescendo–decrescendo cycle. Central neurogenic hyperventilation is rapid and deep with little or no pause and no the characteristic periodic apnea.
