Abstract/OtherAbstract:
BACKGROUND: Manual hyperinflation (MH) is used to improve mucociliary clearance and alveolar expansion in mechanically ventilated patients. Despite the popularity of MH, studies with adults have shown considerable variability in the results from its use. This study assessed if professional training on the application of MH influences its performance. METHODS: An experimental study was conducted with physiotherapists including 11 with previous professional experience (experienced) and 11 without previous experience (inexperienced). They applied MH in a test lung model using self-inflating bags (SIBs) in two sizes (infant and pediatric) from three manufacturers (Hudson®, Laerdal®, and J.G.Moriya®). The test lung simulated the lung mechanics of a newborn and a pediatric patient in two different clinical situations: at normal and reduced compliance. The professionals were instructed to perform MH as described in the literature. Measurements of inspiratory volume (IV), peak inspiratory pressure (PIP), peak inspiratory flow (PIF), and peak expiratory flow (PEF) were recorded using a pneumotachograph in each condition. RESULTS: The delivered PIF was higher in the experienced group (p=0,029) than in the inexperienced group. This result was observed in both, neonatal and pediatric SIBs. There was no difference in the parameters delivered between the experienced and inexperienced groups. CONCLUSIONS: The overall MH's performance was similar between the experienced and inexperienced groups; the only difference was the observation of the highest PIF in the results from the experienced group.
