Longitudinal Dispersion of Composition Differences in the Airways of the Lung.
Abstract
The report describes a study designed to estimate the degree of mixing of gases occurring in the airways of the lung--particularly in the diver at pressure. It has shown the following: Back-mixing is very beneficial in respiration; Airway system of the lung can be considered to be almost an optimal design for exploiting these benefits--with exercise; With increased pressure, as in diving, there are two opposing effects (1) tendency to increase the length of the turbulent zone and (2) less mixing within each turbulent zone. This may explain the lack of any correlation found so far in dives. (Author)
