Sleep & breathing = Schlaf & Atmung

Obstructive sleep apnea (OSA) is a respiratory disorder that has the potential to negatively impact heart rate variability (HRV) during the sleep cycle. However, it is uncertain whether there is a chronic sleep stage-dependent linear and nonlinear cardiac autonomic impairment in OSA. The aim of this study was to perform HRV analysis in apnea-free samples as well as during stage 2 and rapid eye movement (REM) sleep in mild and moderate OSA (MiOSA and MOSA, respectively) subjects as well as health controls (NonOSA). ⋯ In OSA patients, there is a chronic sleep stage-dependent impairment of linear and nonlinear cardiac autonomic modulation. Interestingly, this impairment may be identifiable during the early stages of the disease.

Comparative Study
Positive airway pressure therapy in patients with opioid-related central sleep apnea.
This study aims to compare treatment response and adherence rate to positive airway pressure (PAP) in patients with opioid-related central sleep apnea (O-CSA) and idiopathic central sleep apnea (I-CSA). ⋯ The presence of O-CSA does not preclude an adequate response to CPAP. Adherence rate to PAP was poor in both the O-CSA and I-CSA groups. Further studies are needed to define optimal adherence rate and long-term benefits of PAP in CSA.

The aim of this study was to assess the construct validity and clinical application of the Pediatric Sleep Survey Instrument (PSSI) as a tool to screen for sleep disordered breathing (SDB) in children. ⋯ The PSSI Sleep Disordered Breathing subscale is a valid tool for screening SDB and daytime sleepiness in children aged 5-10 years.
