Comparative Study
Adaptive pressure support servoventilation: a novel treatment for residual sleepiness associated with central sleep apnea events.
Nasal continuous positive airway pressure (nCPAP) usually reduces sleepiness in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). However, even with regular use of nCPAP, some OSAHS patients experience residual sleepiness (RS). The aim of this study was to evaluate the efficacy of adaptive servoventilation (ASV) on RS in OSAHS patients. ⋯ ASV treatment could significantly improved RS in OSAS patients; the mechanism of such an efficacy might be associated with further declined levels of AHI, CSAI, and arousal index.

Obstructive sleep apnea (OSA) remains underdiagnosed, despite our understanding of its impact on general health. Current screening methods utilize either symptoms or physical exam findings suggestive of OSA, but not both. The purpose of this study was to develop a novel screening tool for the detection of OSA, the NAMES assessment (neck circumference, airway classification, comorbidities, Epworth scale, and snoring), combining self-reported historical factors with physical exam findings. ⋯ The NAMES assessment is an effective, inexpensive screening strategy for moderate to severe OSA.

This study aimed to determine the characteristics of respiratory events in preterm infants with clinically concerning apnoea at or beyond 35 weeks postmenstrual age and to compare these findings with a group of preterm infants ready for discharge, without clinically concerning apnoea. ⋯ Preterm infants with clinically concerning apnoea have similar amounts and types of apnoea but lower oxygen saturation after apnoea compared with controls. The use of oxygen saturation monitoring is more useful than respiratory monitoring alone in recognising these events.

Insomnia and obstructive sleep apnea (OSA) are the two most common sleep disorders. Studies have shown that complaints of insomnia are prevalent among sleep clinic patients evaluated for OSA. Less is known about the gender and ethnic variations in this association. ⋯ There is a higher prevalence of insomnia in OSA patients. Ethnicity and gender possibly exhibit a complex and significant influence on the reported subtype of insomnia. Further larger studies may help confirm, as well as clarify, mechanisms that underlie the ethnic and gender differences that we have noted.

Portable sleep apnea monitors are often used to screen for sleep-disordered breathing in chronic heart failure patients (CHF), but night-to-night repeatability of obtained measurements of nocturnal breathing disorders has not been fully assessed. ⋯ In patients with heart failure, measurements of severity of sleep-disordered breathing derived from portable sleep apnea monitors show significant night-to-night intra-subject variation with a negligible contribution from intra-rater variability; however, using the same measurements for classification purposes, as commonly performed in clinical practice to screen patients for sleep-disordered breathing, very stable results are obtained.
