Which abnormal breathing pattern is characterized by a gradual increase and decrease in breathing depth followed by apnea?

• A. Kussmaul Breathing
• B. Biot's Respiration
• C. Apnea
• D. Cheyne-Stokes Respiration

Answer: (D)

Cheyne-Stokes respiration is a rhythmic breathing pattern in which the depth and rate gradually increase, then decrease, followed by a pause in breathing (apnea) before the cycle repeats. The apneic interval typically lasts 10–60 seconds, and the entire cycle can take from a half minute to a couple of minutes. This waxing and waning occur because of a delayed feedback in the brain’s respiratory control centers, and it is often seen in serious conditions such as advanced heart failure or central nervous system injuries. It differs from other patterns by its regular crescendo-decrescendo flow with a distinct apnea, whereas Kussmaul breathing is steady, deep, and rapid with no apnea, and Biot’s respiration shows irregular clusters of breaths followed by unpredictable pauses. So the described pattern matches Cheyne-Stokes respiration.
