- Primary Outcome Measures
Name Time Method Decrease in the prevalence of atelectasis. It is expected that the application of positive pressure to decrease the prevalence of atelectasis in the report of the chest radiograph.;Maintenance of the pulmonary function and the expiratory reserve volume. It is expected that with the application of positive pressure, there is maintenance of lung volumes measured by spirometry the second postoperative day.;Maintenance of diaphragmatic and thoracoabdominal mobility. It is expected that there is maintenance of thoracoabdominal mobility measured by the circumference, and diaphragmatic excursion, measured by chest radiography, inspired and expired.;Decreased duration of invasive mechanical ventilation. It is hoped that with improved gas exchange there faster extubation and shorter duration of invasive mechanical ventilation.
- Secondary Outcome Measures
Name Time Method It is expected that there is less sensation of dyspnea reported by individuals.
