Fig. 3

Inspiratory pressure time product (PTP) under different gain levels. PTP calculated from the difference between the oesophageal pressure and the relaxed chest wall elastance curve (PTP oes ) decreased progressively with increasing gain with or without intrinsic positive end-expiratory pressure (PEEPi). For PTPoes, a significant difference was found between proportional assist ventilation 20% gain (PAV20) vs. PAV40, PAV50, PAV60, PAV70, and PAV80; PAV30 vs. PAV50, PAV60, PAV70, and PAV80; PAV40 vs. PAV60, PAV70, and PAV80; PAV50 vs. PAV70 and PAV80; PAV60 vs. PAV80; and PAV70 vs. PAV80. Similar patterns were found with PTPoes, PEEPi. Values in parentheses are the number of breaths analysed in each gain level
