Journal ArticleDOI
Evaluation of droplet dispersion during non-invasive ventilation, oxygen therapy, nebuliser treatment and chest physiotherapy in clinical practice: implications for management of pandemic influenza and other airborne infections
Anita K. Simonds,A. Hanak,Michelle Chatwin,Mary J. Morrell,A Hall,Kim H. Parker,Jennifer H. Siggers,Robert Julian Dickinson +7 more
TL;DR: The findings suggest that health-care workers providing NIV and chest physiotherapy, working within 1 m of an infected patient should have a higher level of respiratory protection, but that infection control measures designed to limit aerosol spread may have less relevance for these procedures.
Journal ArticleDOI
The effect of sleep on reflex genioglossus muscle activation by stimuli of negative airway pressure in humans.
TL;DR: It is shown that non‐REM sleep attenuates reflex genioglossus muscle activation by stimuli of negative airway pressure, which may have implications for the pathogenesis of obstructive sleep apnoea.
Journal ArticleDOI
Progressive Retropalatal Narrowing Preceding Obstructive Apnea
TL;DR: Results show that expiratory narrowing produced a significant reduction of CSA at end-expiration prior to obstructive apnea.
Journal ArticleDOI
Sleep fragmentation, awake blood pressure, and sleep-disordered breathing in a population-based study.
TL;DR: Using data from the Wisconsin Sleep Cohort Study, the hypothesis that sleep fragmentation is associated with elevated awake blood pressure was tested and the SFI was significantly associated with higher levels of awake systolic blood pressure in people with an AHI < 1.
Journal ArticleDOI
Effect of induced hypocapnic hypopnea on upper airway patency in humans during NREM sleep.
M. Safwan Badr,Abdulmassih Kawak,James B. Skatrud,Mary J. Morrell,Brian R. Zahn,Mark A. Babcock +5 more
TL;DR: The reduction in Vmax during hypopnea in subjects with IFL during eupneic control, suggests that reduced drive is associated with increased upper airway compliance in these subjects, andupper airway susceptibility to narrowing/closure is an important determinant of the response to inducedhypopnea during NREM sleep.
