Cheyne Stokes respirations are described as:

Cheyne Stokes respirations are described as:

• A. An abnormal breathing pattern characterized by progressively deeper and faster breathing, followed by a gradual decrease that results in a temporary stop and apnea.
• B. Rapid, shallow breathing
• C. Irregular breathing without apnea
• D. Normal breathing

Answer: (A)

This question tests recognizing a cyclical, waxing and waning breathing pattern with pauses. Cheyne-Stokes respiration consists of a sequence where breaths gradually become deeper and sometimes faster (crescendo), then gradually become shallower until a brief stop in breathing occurs (apnea), and this whole cycle repeats. The presence of regular apneic intervals is the hallmark that sets it apart from normal breathing or from patterns that are simply rapid and shallow or irregular without pauses. This pattern often appears in patients with central nervous system issues or severe heart problems, and can occur during sleep. So the description of progressively deeper and faster breaths followed by a gradual decrease to apnea captures the distinctive cycle, distinguishing it from rapid shallow breathing, irregular breathing without apnea, or normal breathing.
