Data are presented as mean ± SD. Delta: end – baseline values. SF: square flow, DF: decelerating flow, SF_EIP: square flow with end-inspiratory pause, DF_EIP: decelerating flow with end-inspiratory pause. Pawm: mean airway pressure (cm H₂O) PIP: Peak inspiratory pressure (cm H₂O), Crs: respiratory system compliance (ml cm H₂O⁻¹).
*when significant, P <0,05.
