Pharyngeal narrowing/obstruction during sleep is often described as
an inspiratory phenomenon resulting from obstructive
hypopnea/apnea. It is unknown, however, whether central hypopnea
can lead to airway narrowing. This book reviews recent orginal
studies that evaluated changes in upper airway mechanics and
caliber during sleep using imaging techniques. The main findings of
this book is that upper airway is narrower during central hypopnea
predominantly during the expiratory phase. The inhibition of
ventilatory motor output during sleep increases expiratory retro
palatal compliance. The increased airway resistance, reduced
pharyngeal caliber, and increased pharyngeal compliance as a result
of hypocapnia, indicates its possible role in the pathogenesis of
upper airway obstruction during sleep.
