Automatic EPAP intelligent volume-assured pressure support is effective in patients with chronic respiratory failure: A randomized trial.

Background And Objective: Patients with chronic respiratory failure are increasingly managed with domiciliary non-invasive ventilation (NIV). There may be limited ability to provide NIV titration for these complex patients, and ventilatory requirements and upper airway support needs may change over time. Therefore, an automatically adjusting expiratory positive airway pressure (AutoEPAP) algorithm may offer advantages over manually adjusted EPAP for treating these patients.

Polysomnographic characteristics of adolescents with asthma and low risk for sleep-disordered breathing.

Purpose: The aim of this study was to describe the polysomnographic characteristics of adolescents with asthma who are at low risk for sleep-disordered breathing (SDB) based on the Pediatric Sleep Questionnaire (PSQ).

Methods: Overnight polysomnography was performed on 85 adolescents with asthma and a score < 0.33 on the PSQ.

Neurocognitive performance in insomnia disorder: The impact of hyperarousal and short sleep duration.

Given the recent evidence on the association between hyperarousal in insomnia disorder and neurocognitive deficits, we aimed to examine the effect of short sleep duration on neurocognitive reaction time tests in insomnia disorder sufferers. We recruited subjects with insomnia disorder (n = 35, mean age = 40.6 years) who scored ≥29 on a Hyperarousal Scale, and a group of controls (n = 54, mean age = 31.

Chronic obstructive pulmonary disease and sleep related disorders.

Purpose Of Review: Sleep related disorders are common and under-recognized in the chronic obstructive pulmonary disease (COPD) population. COPD symptoms can disrupt sleep. Similarly, sleep disorders can affect COPD.

Managing Comorbid Illness in Obstructive Sleep Apnea: What Can We Learn from Other Diseases?

Obstructive sleep apnea (OSA) is associated with numerous comorbid medical conditions. Symptoms of OSA may mimic those of comorbid conditions. The presence of OSA may worsen outcomes from the primary condition.

Sleep and the Endocrine System.

In this article, the effect of sleep and sleep disorders on endocrine function and the influence of endocrine abnormalities on sleep are discussed. Sleep disruption and its associated endocrine consequences in the critically ill patient are also reviewed.

Detection of upper airway status and respiratory events by a current generation positive airway pressure device.

Study Objectives: To compare a positive airway pressure (PAP) device's detection of respiratory events and airway status during device-detected apneas with events scored on simultaneous polysomnography (PSG).

Design: Prospective PSGs of patients with sleep apnea using a new-generation PAP device.

Settings: Four clinical and academic sleep centers.

Excessive sleepiness.

Sleepiness is a commonly experienced symptom affecting up to one-fifth of the population chronically. Sleepiness contributes to systemic health effects, and has been shown to contribute to mood disorders and cardiovascular risks. Sleepiness also presents a significant public health risk: it has been associated with major catastrophes, motor vehicle accidents, and medical errors by health care workers.
