Primary Outcome Measures

Name	Time	Method
To evaluate the effectiveness of non-invasive preventive ventilation in respiratory function in the postoperative period of bariatric surgery by Roux Y in adults.

Secondary Outcome Measures

Name	Time	Method
Assess the impact of this intervention on pulmonary function and respiratory muscle strength, comparing a group of obese patients undergoing this intervention to a control group, which will be submitted to conventional chest physiotherapy. <br>Analyze volumes, lung capacity and peak expiratory flow through respirometry and peak flow, respectively: <br>• Slow Vital Capacity (VC) <br>• inspiratory capacity (IC) <br>• Minute volume (MV) <br>• Tidal volume (VT) <br>• Peak expiratory flow (PEF) <br>Measure respiratory muscle strength and lung function by spirometry and manometer, respectively: <br>• inspiratory muscle strength (MIP) <br>• expiratory muscle strength (MEP) <br>• Forced vital capacity (FVC) <br><br>check: <br>• Episodes of pulmonary complications in the postoperative <br>• Episodes of postoperative complications <br>• Days of hospital stay
