This accounts for the fact that UA dilator muscles play a determinant role in maintaining UA patency (UA resistance) and stability (UA collapsibility). airway resistance breathing route...

... 30 min before, the start of exercise. 2. With no medication, transpulmonary index (TPI), a measure of airway resistance, fell linearly during exercise from a resting value of 0.269 ± 0.024 to 0.170 ± 0.014 kPa·1 −1 ·s by the end of exercise. This returned to baseline between 2 and 4 min after...

..., both affecting both large and small airways, and produce similar degrees of bronchodilatation. This is supported by our results after the helium/oxygen breathing, where the lack of change in density dependence of maximal flow suggests that there was no change in the distribution of airways resistance...

Asthmatic airways appear to be relatively protected from developing resistance when compared with other tissues in asthmatic patients and when compared with the airways of normal subjects. adrenergic resistance airway resistance...

...T. Higenbottam; T. J. H. Clark 1. Airway resistance was measured close to functional residual capacity before and after a full inhalation of total lung capacity, as well as before and after a full exhalation to residual volume. 2. The effects of these volume manoeuvres upon airway resistance...

...T. Higenbottam; T. J. H. Clark 1. The inverse relationship between airway resistance and lung volume contributes to variation in measurement of resistance, as it is difficult to control precisely the lung volume at which resistance is determined each time. A correction for variation in lung volume...
