Upper airway reflexes and obstructive sleep apnoea.
Reflexes originated from the supralaryngeal airways, larynx and lungs can affect upper airway calibre r 11. Specific receptors at the lnryngeal level have been thought to be involved 12J. N~tsal obstruction in normal men m<\y cause apnoeas allll in addition. more arousals and full awakenings from sleep [3]. The underlying mechanism remains unclear. It was demonstrated that nasal occlusion incre...
متن کاملEvaluation of the upper airway in obstructive sleep apnoea.
The evaluation of the upper airway (UA) includes the physical examination of pharyngeal structures and a number of imaging techniques that vary from the mostly used lateral cephalometry and computed tomography to more sophisticated methods such as tri-dimensional magnetic resonance image (MRI). Other complex techniques addressing UA collapsibility assessed by measurement of pharyngeal critical ...
متن کاملCentral sleep apnoea syndrome with upper airway collapse.
We report on an 83 yr old man with hypersomnia and central sleep apnoea (CSA). He had several possible causes for CSA, including a central nervous system lesion, hypocapnia and anatomical narrowing of the airway at the hypopharyngeal level. We postulate that reduced central respiratory drive occurring in conjunction with upper airway narrowing may have led to central apnoeas. These in turn coul...
متن کاملSleep and daytime sleepiness in upper airway resistance syndrome compared to obstructive sleep apnoea syndrome.
This study has investigated differences in the nocturnal sleep and daytime sleepiness among patients with obstructive sleep apnoea syndrome (OSAS), upper airway resistance (UARS), sleep hypopnoea syndrome, and normal control subjects, using sleep scoring and spectral activity analysis of the electroencephalogram (EEG). Twelve nonobese males with UARS aged 30-60 yrs were recruited. These subject...
متن کاملEffect of upper-airway stimulation for obstructive sleep apnoea on airway dimensions.
Upper-airway stimulation (UAS) using a unilateral implantable neurostimulator for the hypoglossal nerve is an effective therapy for obstructive sleep apnoea patients with continuous positive airway pressure intolerance. This study evaluated stimulation effects on retropalatal and retrolingual dimensions during drug-induced sedation compared with wakefulness to assess mechanistic relationships i...
