BACKGROUND: Sleep is a risk factor for @entity1576 in @entity1 with chronic @entity4094 ( @entity4094 ). OBJECTIVE: To explore the diagnostic value of monitoring sleep parameters in addition to nocturnal respiratory parameters. METHODS: Thirty-one @entity1 with chronic @entity4094 underwent whole-night polysomnograms including EMG from accessory respiratory muscles. RESULTS: Sleep macrostructure was normal on average. The number of respiratory arousals per hour of sleep was above the upper limit observed in a control group (>2.1) in 71% of the @entity1 , but was moderate in most cases. Nadir @entity26 saturation <85% was the most common finding indicating @entity1576 and was present in 80% of the @entity1 . Noninvasive blood gas monitoring identified all but 2 @entity1 with respiratory-induced @entity25 . The respiratory arousal rate was correlated with the @entity26 desaturation index, but otherwise there were no significant correlations between @entity1576 . Vital capacity was significantly positively correlated with obstructive @entity386 index and daytime base excess to nadir @entity26 saturation. Inspiratory activity in accessory respiratory muscles was present during REM sleep and/or slow wave sleep in 70% of the @entity1 . CONCLUSION: The severity of nocturnal @entity1576 is not reflected in the extent of @entity25 in @entity1 with chronic @entity4094 .
