Abstract

A patient with adult‐onset spinal muscular atrophy causing mild proximal limb muscle weakness had sleep‐induced nonobstructive hypoventilation due to diaphragmatic paralysis. Nocturnal dyspnea and daytime somnolence were associated with frequent arousals from sleep due to arterial oxygen desaturation. The nocturnal use of a cuirass respirator improved the oxygen saturation, resulting in less disrupted sleep, relief of the somnolence, and improved daytime ventilation.
