Impact of positive end-expiratory pressure on chest wall and lung pressure-volume curve in acute respiratory failure

摘要

To investigate whether chest-wall mechanics could affect the total respiratory system pressure-vol- ume (P-V) curve in patients with acute respiratory failure (ARF), and particularly the lower inflection point (LIP) of the curve, we drew the total respiratory system, lung, and chest-wall P-V curves (P-Vrs, P-V_L, and P-Vw, respectively)
