Even fewer studies have compared ventilator hyperinflation with the vibrocompression.Objective: To compare the effects of two chest physiotherapy protocols on lung mechanics and cardiorespiratory parameters in patients undergoing mechanical ventilation.Methods: A quasi-experimental study that included 50 critical patients (mean age 55,6±15,3 years old) who were receiving mechanical ventilation for more than 48 hours.The subjects were allocated into three groups: aspiration (control, n=16); vibrocompression and aspiration (n=17); vibrocompression, aspiration and ventilator hyperventilation (n=17). Heart rate, respiratory rate, blood pressure, oxygen saturation, static and dynamic lung compliance, and airway resistance were measured and compared between three groups before (baseline), immediately after and 15 minutes after the end of each protocol. For statistical analysis were used, Shapiro-Wilk test and one-way ANOVA with the post-hoc Bonferroni test (p≤0.05).Results: There were no significant differences in the lung mechanics and cardiorespiratory parameters between the 3 periods (before, immediately after and 15 minutes after the end of each protocol) endotracheal suctioning) into the groups.Conclusions: Chest physiotherapy can be safely on patients undergoing mechanical ventilation, although this study suggests that the use of ventilator hyperinflation isolated or associated vibrocompression does not improve lung mechanics in this population of mechanically ventilated patients.
