From: Improving lung compliance by external compression of the chest wall
Hypothetical effects of external loading on the compliance characteristics of the lung and chest wall for an unchanging tidal volume. External loading improves the tidal compliance of the lung with severe ARDS by causing leftward migration of tidal transpulmonary tidal pressures. (Dots depict the end-expiratory and end-inspiratory positions prior to loading, and triangles their positions with external load in place.) Normal chest wall and lung pressure volume curves are provided for reference
