A Case Report of Obstructive Sleep Apnea Syndrome Admitted To the Hospital with Chronic Cough

Abstract

Obstructive Sleep Apnea Syndrome is characterized by recurrent upper respiratory tract obstruction episodes during sleep. The aperture of the upper respiratory tract during sleep depends on the equilibrium between the collapsing effect of the negative pressure that occurs within the pharyngeal lumen during inspiration, and the powers that maintain the aperture of the upper respiratory tract. Obstructive sleep apnea syndrome with chronic cough is a rare situation. These two symptoms together make the patient feel more dyspneic both in sleep and awake states. In cases of incurable cough, obstructive sleep apnea syndrome should be considered. The current study presents a case of chronic cough, which was not cured despite appropriate treatment and displayed REM-induced sleep apnea in polysomnography.
