High-Frequency Percussive Ventilation in Viral Bronchiolitis

Respiratory Care, 2022
High-frequency percussive ventilation (HFPV) is an alternative mode of mechanical ventilation that has been shown to improve gas exchange in subjects with severe respiratory failure. We hypothesized that HFPV use would improve ventilation and oxygenation in intubated children with acute bronchiolitis.In this single-center prospective cohort study we ...
