Effects of Physiotherapy in Hemodynamics and Childrens Respiratory Mechanics

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.

To perform the TVC technique, we applied 10 vibrocompression maneuvers on the chest of the children during the expiratory phase of the respiratory cycle, on each of the lateral decubitus position, totaling 20 maneuvers, followed by aspiration in the dorsal decubitus position. All measurements in both study groups were performed with the child connected to the ventilator. Before starting the maneuver BS or TVC the child received an increase of 20% fraction of inspired oxygen (FiO2) from what was received previously in MV and after data collection FiO2 returned to baseline values.
