Figure 3. Slopes of the relationships between force and rib displacement and between force and airway opening pressure for the different ribs.
The data in A are the mean ± s.e.m. values of axial rib displacement per unit force (Xr/F) obtained from six animals during cranial loading of the odd-numbered rib pairs (filled circles) and during caudal loading of the even-numbered rib pairs (open circles). Positive values indicate displacements in the cranial direction and negative values indicate displacements in the caudal direction. The data in B are the corresponding mean ± s.e.m. values of ΔPa,o per unit force.
