Which term describes an irregular, unpredictable breathing pattern with irregular apneic periods?

• A. Cheyne-Stokes
• B. Apneusis
• C. Ataxic
• D. Cluster

Answer: (C)

Ataxic breathing describes an irregular, unpredictable pattern in which the depth and rate of breaths vary chaotically and apneic periods occur irregularly. This reflects a loss of the normal respiratory rhythm, often due to severe brainstem dysfunction, so there’s no repeating cycle to latch onto. This differs from Cheyne-Stokes breathing, which has a recognizable cycle of gradually increasing then decreasing depth followed by a regular pause. Apneusis features a prolonged inspiratory pause at the end of inspiration, giving a characteristic “stopped-in” feel to the breath. Cluster breathing shows groups of rapid breaths clustered together with short pauses, a pattern that’s grouped rather than completely irregular. So the term that best matches an irregular, unpredictable breathing pattern with irregular apneic periods is ataxic breathing.
