Pulmonary damage dose response. The required model shunt to account for steady-state arterial oxygen concentration changes in experimental damage plotted as a function of fractional lung weight change. Damon et al. (diamonds) reports values for individual sheep placed sheep in shock tubes. Dodd et al. (squares) reports mean values for groups of sheep in response to 3 shock tube damage levels. Julien et al. (triangles) measured the dose response of oleic acid treatment.
