摘要

Obstructive nonapneic respiratory events (ONAREs) are much more difficult to detect and classify than apneas unless sensitive measures of respiratory effort and airflow are employed. The aim of this study was to compare two measures of respiratory effort, esophageal pressure monitoring (Pes) and pulse transit time (PTT), for scoring of ONAREs by visual analysis. Nine men (age 49 ± 10 yr) with mild to moderate sleep apnea syndrome (AHI of 25.1 ± 10.8/h) were studied and 340 ONAREs (hypopneas and upper air - way resistance episodes) were randomly selected for scoring by two experienced observers. Each observer blindly scored each ONARE twice (once with Pes and once with PTT) with a concurrent Pneumotachography trace available for airflow quantification.
