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
