Background There is a scarcity of published data on the global prevalence of obstructive
sleep apnoea, a disorder associated with major neurocognitive and cardiovascular sequelae. …

Upper airway obstruction is common during both anaesthesia and sleep. Obstruction is caused
by loss of muscle tone present in the awake state. The velopharynx, a particularly narrow …

Obstructive sleep apnea (OSA) is a nocturnal breathing disorder that is associated with
cognitive impairment. The primary determinants of cognitive deficits in OSA are thought to be …

Background This study investigated the effect of varying concentrations of propofol on upper
airway collapsibility and the mechanisms responsible for it. Methods Upper airway …

BACKGROUND: The six minute walk test (6MWT) is the most commonly used exercise test
in pulmonary rehabilitation; however, the paucity of six minute walk distance (6MWD) …

Background: Reduced upper airway muscle activity during sleep is fundamental to obstructive
sleep apnea (OSA) pathogenesis. Hypoglossal nerve stimulation (HGNS) counteracts this …

Background Upper airway collapsibility is known to increase under anesthesia. This study
assessed how this increase in collapsibility evolves during slow Propofol induction and how it …

Objectives: To investigate cardiorespiratory and dyspnea responses to incremental and self-paced
exercise tests in patients with COPD. Design: A prospective within-subject design …

Background The unprotected upper airway tends to obstruct during general anesthesia, yet
its mechanical properties have not been studied in detail during this condition. Methods To …

The aim of the present study was to investigate the effects of an interval-based high-intensity
inspiratory muscle training (H-IMT) programme on inspiratory muscle function, exercise …
