Cheyne-Stokes respirations can precede death.

• A. They can precede death
• B. They indicate full recovery
• C. They have no clinical significance
• D. They indicate a good prognosis

Answer: (A)

Cheyne-Stokes respirations are a pattern of periodic breathing where breaths gradually become deeper and sometimes faster, then slower and shallower, followed by a period of apnea. This cycle happens when the brain’s control of breathing and the body's oxygen–carbon dioxide balance become unstable, a situation common in advanced disease. In end-of-life states—such as severe heart failure, stroke, or extensive brain injury—the respiratory drive and circulation weaken, producing this characteristic breathing pattern. Because it signals significant deterioration of vital functions and a movement toward death, it can precede death. It’s not a sign of recovery or of no consequence; rather, it points to a poor prognosis as life-sustaining systems fail. While not every patient will display it, its appearance is a meaningful indicator of approaching demise.
