To perform the BS technique, we used a Protec® manual inflation bag with a flow of 10 L / min and 100% oxygen. A Commercial Medical® manometer was adapted between the orotracheal tube and the inflation bag to monitor the inflation pressure which was recommendedat 30 cmH2O for all children of the BS group. Initially we instilled at most 0.5 ml saline solution(SS) at 0.9% followed by 10 manual hyperinflation maneuvers interspersed with 10 vibrocompression maneuvers and as a last procedure, we performed an aspiration of the orotracheal tube airways and mouth. Between the aspirations the child was re-connected to the ventilator.

All variables were assessed prior to the proposed technique (pre-maneuver), immediately after the execution of the technique randomly chosen (post-maneuver), 30, 60 and 120 after the end of the technique randomly chosen. The mean of three readings was used as the representative value for each variable. All children were ventilated with the same mechanical Dixtal® DX3020 Brazil ventilator
