Snoring and upper airway properties.

A Subject-Specific Acoustic Model of the Upper Airway for Snoring Sounds Generation

Monitoring variations in the upper airway narrowing during sleep is invasive and expensive. Since snoring sounds are generated by air turbulence and vibrations of the upper airway due to its narrowing; snoring sounds may be used as a non-invasive technique to assess upper airway narrowing. Our goal was to develop a subject-specific acoustic model of the upper airway to investigate the impacts o...

Neuromechanical interaction in human snoring and upper airway obstruction

Huang, Lixi, and John E. Ffowcs Williams. Neuromechanical interaction in human snoring and upper airway obstruction. J. Appl. Physiol. 86(6): 1759–1763, 1999.—The fact that snoring and obstructive apnea only occur during sleep means that effective neuromuscular functioning of the upper airway during sleep is vital for the maintenance of unimpeded breathing. Recent clinical studies in humans hav...

Increased upper airway collapsibility in children with obstructive sleep apnea during wakefulness.

Upper airway collapsibility (UAC) is increased in children with sleep-disordered breathing (SDB), but during wakefulness, active neural processes preserve upper airway patency, such that measurement of upper airway dynamics using acoustic pharyngometry may contribute to diagnostic accuracy in snoring children. Upper airway cross-sectional area obtained from acoustic pharyngometry measurements w...

Upper airway resistance syndrome (UARS)--simple snoring or mild obstructive sleep apnea.

Evaluation of the Upper Airway in Patients with Snoring and OSA

Snoring and obstructive sleep apnoea (OSA) both exhibit multilevel upper airway obstruction. The Importance of evaluating the dynamics of the obstructing upper airway cannot be emphasised enough. Accurate assessment and evaluation of the upper airway could potentially lead to improved surgical and non-surgical treatment outcomes. Most of these patients would have undergone an ambulatory sleep s...
