Tracheal sound recordings and O2 saturation were compared with conventional recordings of respiratory events (thermistors, strain gauges, and O2 saturation) in 14 patients referred for assessment of sleep apnea syndrome. There was no significant difference in the number of respiratory events associated with desaturation recorded during the sleep by the two methods. Tracheal sound recordings were more useful in analyzing the cause of the respiratory event. Hypopnea without desaturation was seen more often with tracheal sound recordings than with the conventional methods. The durations of apneic and hypopneic events were significantly longer when recorded by thermistors and strain gauges than by breath sounds.
对14名因睡眠呼吸暂停综合征接受评估的患者，将气管音记录和血氧饱和度与呼吸事件的传统记录（热敏电阻、应变计和血氧饱和度）进行了比较。两种方法记录的睡眠期间与血氧饱和度下降相关的呼吸事件数量没有显著差异。气管音记录在分析呼吸事件原因方面更有用。与传统方法相比，气管音记录更常出现无血氧饱和度下降的呼吸浅慢。通过热敏电阻和应变计记录的呼吸暂停和呼吸浅慢事件的持续时间明显长于呼吸音记录的。
