aP < 0.05 compared with T0; bP < 0.05 compared with T20/30. Right ventricular Tei index was calculated as the sum of the isovolumic contraction time and the isovolumic relaxation time, divided by ejection time. T0 = time at baseline; T20/30 = time when positive end-expiratory pressure at 20 cmH2O and driving pressure at 30 cmH2O; TOLP = time at open lung-positive end-expiratory pressure. |
