Abstract:

Airway resistance was measured with a volume displacement body plethysmograph in 40 normal subjects breathing at their spontaneous breathing rate. The measurements are based on a method designed by DuBois et al., which was modified in order to extend its applicability. The subjects were rebreathing from a bag containing gas at approximately BTPS conditions. Possible errors in conditioning the gas in the bag were corrected mathematically. The values of airway resistance obtained 1.26 0.39 cm. H2O per liter per second agree with those published by DuBois et al. and by other authors using the same technic. The measurements were found to correlate with results obtained on the same subjects with related technics. The paper also includes measurements of lung-tissue viscous resistance and inertance of the gas in the airways. Author
