Abstract
The Bohr dead space was calculated from solutions of a transport equation where diffusivity was given by an empirical formula obtained by Sherer. A satisfactory agreement was found with experimental data obtained from simultaneous washouts of H2 and SF6 for respiratory frequencies ranging between 15 and 60 min-1 and tidal volumes between 200 and 1800 ml. Molecular diffusion is apparently the main but not the only physical phenomenon which intervenes in gas mixing during breathing.This publication has 2 references indexed in Scilit:
