Background: Previous studies have shown that changes in lung volume influence upper
airway size and resistance, particularly in patients with obstructive sleep apnoea (OSA), and …

Previous studies have demonstrated that lung volume during wakefulness influences upper
airway size and resistance, particularly in patients with sleep apnea. We sought to determine …

To define the parameters of respiratory insufficiency in OSA, 114 consecutive patients (108
men, six women) were prospectively studied. In addition to standard polysomnography, they …

We studied the influence of lung volumes on apnoea-induced desaturation in ten subjects
with sleep apnoea syndrome. Lung volumes were measured by helium dilution in the sitting …

We have investigated pulmonary hemodynamics in a large series of consecutive,
unselected patients with obstructive sleep apnea syndrome (OSAS). The aims of this study …

Background: A study was undertaken to examine the expiratory flow response to a negative
pressure (NEP) applied at the airway in patients with no abnormalities of the intrathoracic …

Objective: Sleep disordered breathing (SDB), namely hypoventilation and obstructive sleep
apnoea, occur in about 50% of patients with severe chronic obstructive pulmonary disease …

BACKGROUND: There is evidence to suggest that chronic continuous positive airway
pressure (CPAP) therapy may produce reversible changes in upper airway morphology and …

Patients with chronic obstructive pulmonary disease (COPD) exhibit increases in lung
volume due to expiratory airflow limitation. Increases in lung volumes may affect upper …

We describe the reversal of obstructive sleep apnea with a 0.5 L increase in the functional
residual capacity (FRC) in a patient with sleep apnea syndrome. The patient had been …
