| Abstract: | Abstract We investigated the alteration of esophageal pressure (Pes) in 10 patients with upper-airway sleep-disordered breathing (UASDB) and the relationship among Pes, breathing patterns and EEG arousals. Increased negative Pes without apnea or hypopnea, appeared not only in upper airway resistance syndrome but also in obstructive sleep apnea syndrome. This phenomenon produced frequent EEG microarousals leading to sleep fragmentation and daytime sleepiness. Moreover, increased negative Pes occasionally continued for more than 20 min without an EEG arousal, which might be considered to be one of the factors to cause complications of UASDB. |
