... men. Rostral fluid displacement during recumbency may therefore contribute to the pathogenesis of OSA (obstructive sleep apnoea). There is a higher prevalence of OSA in men than in women. We therefore hypothesized that UA collapsibility increases more in men in response to rostral fluid displacement...

...Nigel Mcardle OSA (obstructive sleep apnoea) is a common condition that is strongly associated with cardiovascular disease. It is remains unclear what role OSA plays in determining cardiovascular risk. The immediate physiological changes that occur during upper airway obstruction are potential...

Sanner; Andreas Mügge OSA (obstructive sleep apnoea) stimulates sympathetic nervous activity and elevates resting HR (heart rate) and BP (blood pressure). In the present study...

...Ramon FARRÉ Patients suffering from the obstructive sleep apnoea syndrome (OSAS) experience nocturnal episodes of upper airway obstruction resulting in recurrent oxygen desaturations and arousals. Methods to quantify the nocturnal obstructive events are of interest for characterizing this prevalent...

...C. ZAMARRÓN; P. V. ROMERO; J. R. RODRIGUEZ; F. GUDE Using spectral analysis of oximetry data, we prospectively evaluated the validity of this methodology in patients clinically suspected of suffering from obstructive sleep apnoea (OSA). A total of 233 outpatients were studied. Nocturnal oximetry...

...J. Krieger; M. Follenius; E. Sforza; G. Brandenberger; J. D. Peter 1. Patients with obstructive sleep apnoea have increased diuresis during sleep, which decreases with nasal continuous positive airway pressure treatment. These changes have been attributed to an increased release of atrial...

Plasma levels of atrial natriuretic peptide (ANP) were measured in seven patients with obstructive sleep apnoea (OSA) while they were awake, during repetitive apnoea and during treatment with nasal...

...A. R. H. Warley; J. R. Stradling 1. In healthy individuals, sleep is associated with a fall in urine and sodium output. 2. Seven male patients with obstructive sleep apnoea exhibited a paradoxical rise in both urine and sodium output during the hours of sleep. 3. Continuous positive airway pressure...
