Fig. 3From: Positional effects on the distributions of ventilation and end-expiratory gas volume in the asymmetric chest—a quantitative lung computed tomographic analysisI–IV Total gas volumes at end-inspiration and end-expiration for each position. Please refer to Fig. 1 for nomenclature. Total gas volumes at end-inspiration and end-expiration for each position are displayed. Total gas volume in each phase of the tidal cycle was significantly different within all positions with and without PLEF. Means and standard deviations are shown.
