What term describes a pattern of breathing characterized by alternating periods of slow, irregular respiration and rapid, shallow breaths?

• A. Hyperventilation
• B. Cheyne-Stokes respiration
• C. Apnea
• D. Bradypnea

Answer: (B)

The term that describes a pattern of breathing characterized by alternating periods of slow, irregular respiration and rapid, shallow breaths is Cheyne-Stokes respiration. This type of breathing pattern typically involves a gradual increase in the depth and rate of breathing followed by a decrease, leading to a temporary stop in breathing (apnea). This cycle can repeat several times and is often observed in patients with certain medical conditions, especially those related to heart failure or brain disorders. In contrast, hyperventilation refers to an increased rate and depth of breathing, which can lead to excessive exhalation of carbon dioxide without the alternating pattern described. Apnea signifies a temporary cessation of breathing altogether, lacking the characteristic cycle of varying respiratory patterns. Bradypnea is defined as an unusually slow breathing rate but does not encompass the alternating phases of rapid and slow breaths seen in Cheyne-Stokes respiration. Thus, Cheyne-Stokes respiration accurately captures the specific fluctuation in the breathing pattern outlined in the question.
