Text: The IE index, tidal volume (VT), minute ventilation (VE), coefficient of variation of VT, ventilator inspiratory time (TI), expiratory time (TE), leak volume at 15 cm H2O PS level were significantly higher than those at 5 cm H2O level [IE index : (33. 8 + / -9. 1) % vs. (8. 0 + / -6. 0) %, VT (ml) : 626 + / -203 vs. 339 + / -115, VE (L/min) : 11. 1 + / -4. 7 vs. 7. 7 + / -2. 7, coefficient of variation of VT : (32. 6 + / -15. 5) % vs. (11. 3 + / -6. 9) %, TI (s) : 1. 14 + / -0. 31 vs. 0. 76 + / -0. 15, TE (s) : 2. 49 + / -0. 44 vs. 1. 87 + / -0. 28, leak volume (L/min) : 8. 28 + / -4. 86 vs. 2. 22 + / -1. 58, all P < 0. 05], while the ventilator respiratory rate [(17 + / -3) breaths/min] was lower at 15 cm H2O PS level than that at 5 cm H2O level [(23 + / -3) breaths/min, P < 0. 05].
