Fig. 2From: Dynamics of end expiratory lung volume after changing positive end-expiratory pressure in acute respiratory distress syndrome patientsPercentage of additional volume achieved according to the number of breaths. Box plot shows medians (25th–75th quartiles) for all patients at all positive end-expiratory (PEEP) levels. Left and right panels depict increases and decreases of PEEP, respectively.
