Obstructive sleep apnea (OSA) is two to three times more common in men as in women. The
mechanisms leading to this difference are currently unclear but could include gender …

Ventilatory instability may play an important role in the pathogenesis of obstructive sleep
apnea. We hypothesized that the influence of ventilatory instability in this disorder would …

Abstract Study Objectives: To compare the breathing instability and upper airway
collapsibility between patients with pure OSA (ie 100% of apneas are obstructive) and …

Male sex, obesity, and age are risk factors for obstructive sleep apnea, although the
mechanisms by which these factors increase sleep apnea susceptibility are not entirely …

Abstract Study Objectives: Certain respiratory control characteristics determine whether
patients with collapsible upper airway develop stable or unstable breathing during sleep …

Rationale: There is increasing evidence of increased ventilatory instability in patients with
obstructive sleep apnea (OSA), but previous investigations have not studied whether the …

Changes in sleep posture have been shown to improve obstructive sleep apnea (OSA). To
investigate the mechanisms by which this occurs we assessed upper airway stability in eight …

Study objectives: Obstructive sleep apnea (OSA) resolves in lateral sleep in 20% of patients.
However, the effect of lateral positioning on factors contributing to OSA has not been …

OBJECTIVE: Obstructive sleep apnea (OSA) is far more common in males than females. The
discrepancy between the lower prevalence of OSA, the greater frequency of obesity and the …

The male predominance in obstructive sleep apnea (OSA) is currently poorly understood
although differences in pharyngeal airway anatomy and physiology have been proposed. As …
