WebUpper airway resistance syndrome (UARS) is a condition that was first identified and described at Stanford University. It is very similar to obstructive sleep apnea (OSA) in that the soft tissue of the throat relaxes, reduces the size of the airway, and results in disturbed sleep and consequent daytime impairment, including excessive daytime sleepiness. Web26 de set. de 2024 · When people say "respiratory resistance", they usually mean airway resistance, i.e. the pressure generated by the resistance to gas flow produced by the walls of the airways. This pressure, and how it is affected by different factors, depends on what type of flow is occurring, which in turn affected by Reynold's number.
