The prediction of pressure drop and variation of resistance within the human bronchial airways
TJ Pedley, RC Schroter, MF Sudlow - Respiration physiology, 1970 - Elsevier
Pressure drop and distribution of resistance within the lower airways on inspiration are
predicted, from the theory developed earlier, for a wide range of flow rates using a
symmetrical rigid model of the anatomy of the bronchial tree based upon data from lungs
fixed at 75% TLC. The resistance depends upon flow rate, the major part being in the
trachea and larger bronchi. Airways beyond generation 10 (diameter approximately 0.5 mm)
contribute less than 10% to lower AWR. The overall pressure drops obtained are in close …
