Which breathing pattern commonly occurs during the dying process?

• A. Diaphragmatic breathing with constant rate
• B. Apnea only
• C. Cheyne-Stokes pattern breathing
• D. Hyperventilation with regular rhythm

Answer: (C)

Breathing during the dying process often becomes irregular and cyclical. Cheyne-Stokes respiration features a pattern where breaths gradually become deeper and sometimes faster, then slowly grow shallower until a period of apnea occurs, and the cycle repeats. This waxing-and-waning rhythm reflects changes in brainstem control of respiration as metabolic demands fall and blood flow to the brain shifts during decline. It’s a common end-of-life pattern, illustrating how the body’s respiratory regulation changes as life wanes. Other patterns like a constant diaphragmatic rhythm, hyperventilation with regular rhythm, or apnea occurring without cyclical variation don’t fit this typical dying pattern as well.
