Nasal mucociliary transport is impaired at altitude.
There have been a number of anecdotal reports of rhinitis and nasal obstruction occurring at altitude. To quantify these reports, we investigated nasal obstruction and mucociliary transport in a group of healthy volunteers trekking to Mount Everest Base Camp, Nepal, altitude 5,300 m. Nasal obstruction was estimated by subjective scoring and mucociliary transport was determined by the saccharin ...

متن کاملNasal mucociliary transport in healthy subjects is slower when breathing dry air.
We assessed the effect of dry air (DA) nasal breathing on nasal clearance rate in healthy nonsmoking subjects. We measured saccharin nasal transit time (SNTT), an index of mucociliary clearance rate, in eleven normal subjects (six males, five females) breathing either room air (RA) or DA through the nose in random order on six different study days. On each study day, the trial was conducted at ...
متن کاملNasal airflow resistance at simulated altitude.
This issue includes an important paper by BARRY et al. [1] in which the changes in nasal peak inspiratory flow (NPIF), and oral peak inspiratory flow (OPIF), during acclimatized exposure to low barometric pressure (equivalent to a simulated altitude of 8000 m, about the height of Mount Everest) of subjects in a hypobaric chamber were analysed. The changes were presumably due to hypoxia and its ...
متن کاملMeasurement of nasal mucociliary clearance.
The saccharin test was carried out in a randomly selected sample of schoolchildren (142 boys and 153 girls, age range 11-14 years) to determine the variability and reproducibility of the test and to assess whether it could be used as a screening test for nasal mucociliary clearance. Nasal mucociliary clearance times were analysed according to clinical history (asthma, rhinitis, asthma with rhin...
