sleepiness/hypoxia

To determine whether defining two subtypes of sleep-disordered breathing (SDB) events-with or without hypoxia-results in measures that are more strongly associated with hypertension and sleepiness. A total of 1022 participants with 2112 nocturnal polysomnograms from the Wisconsin Sleep Cohort were

OBJECTIVE To evaluate the intensity of nocturnal hypoxemia associated with sleepiness in Peruvian men with a diagnosis of obstructive sleep apnea (OSA). METHODS We carried out a secondary data analysis based on a study which includes patients with OSA who were seen in a private hospital in Lima,

OBJECTIVE This study aims to assess the association between excessive daytime sleepiness (EDS) and variables extracted from the pulse-oximetry signal obtained during overnight polysomnography. METHODS A cross-sectional design was used to study the relation between four hypoxemia variables and EDS as

OBJECTIVE Adult male mice exposed to long-term intermittent hypoxia (LTIH), modeling sleep apnea oxygenation patterns, develop nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-dependent residual hypersomnolence and oxidative injury in select brain regions, including wake-active regions.

Fourteen patients with chronic obstructive pulmonary disease (COPD) and chronic hypoxemia were studied to evaluate the relationship between hypoxemia and objective and subjective daytime sleepiness. Patients were selected with a waking PaO2 of less than 70 mm Hg and less than 50 percent predicted

To determine the effects of intermittent hypoxemia on daytime sleepiness in the clinical setting of obstructive sleep apnea syndrome, we enrolled seven patients in a prospective, randomized, crossover study. We had two experimental conditions with NCPAP treatment as follow: (1) to correct apneas,

The possible relationship between lung cancer and nocturnal intermittent hypoxia, apnea and daytime sleepiness, especially the possible relationship between the occurrence and progression of lung cancer and obstructive sleep apnea syndrome (OSAS) was explored. Forty-five cases of primary lung cancer

This study evaluated the relationship between neuropsychological and affective functioning, subjective sleepiness and sleep-disordered breathing in 100 patients with obstructive sleep apnea (OSA). Using principal components analysis, three indices of sleep-disordered breathing were identified from

Patients with sleep apnea are typically hypersomnolent during the daytime and may demonstrate higher order cognitive dysfunction. A persistent problem in interpreting impaired neuropsychological test performance in such patients is whether the observed deficits can be explained wholly by impaired

Two cases of myotonic dystrophy with excessive daytime somnolence are described. All-night polysomnographic studies were performed revealing high number of central sleep apnea which triggered micro-arousals and awakenings leading to decrease of sleep efficiency as well as of stage 3, 4 and REM.

Daytime sleepiness is one of the major symptoms of obstructive sleep apnea. However, its definition raises problems, since it may be based on either subjective feeling (evaluated by means of questionnaires or analog visual scales), physiological drive or need (inferred by a sleep latency) or on the

Excessive daytime sleepiness (EDS) is the major symptom of patients with obstructive sleep apnea syndrome (OSAS). In this study, we examined the relationship between subjective EDS scored with the Epworth Sleepiness Scale (ESS), objective EDS measured with the multiple sleep latency test (MSLT) and
