EPAP
The EPAP will be applied with a Spring Load Valve Resistor (Vital Signs, Totowa, NJ, USA), adjusted with a pressure of 10 cmH2O. The Spring Load Valve Resistor will be connected to the expiratory branch of the T-tube. Duration of intervention: 5 minutes.
Breath Stacking
The BS will be performed by a T-tube with a one-way inspiratory valve and the expiratory branch occluded. The expiratory occlusion is maintain until observed the presence of a plateau in the impedance plethysmogram by EIT, which corresponds to the absence of inspired air displacement or when a maximum time of 40 seconds was attained. Durantion of intervention:Three BS interventions will be performed at one minute intervals between them.
