Fig. 5From: Positional effects on the distributions of ventilation and end-expiratory gas volume in the asymmetric chest—a quantitative lung computed tomographic analysisPositional changes in end-expiratory volume collapsed and tidal recruitment of the collapsed lung. The average percentage of end-expiratory volume collapsed did not change as horizontal positions varied (a). Compared to other horizontal positions, supine showed a significantly higher percentage of tidally recruited collapsed lung volume (b). Means’ percentage and standard deviations are shownBack to article page
