González-Bellido V, Velaz-Baza V, Blanco-Moncada E, et al. - Researchers conducted this randomized clinical trial to assess the immediate effects and safety of high-frequency chest wall compression (HFCWC) as compared to airway clearance techniques in non-hospitalized infants (0–12 months old) with mild to moderate acute viral bronchiolitis (AVB). Study participants were randomized into 2 groups: airway clearance techniques (20 min of prolonged slow expiration and provoked cough) or HFCWC (15 min). In total, 91 infant participants, mean age 7.9 ± 2.6 months, were involved. Findings suggested that the use of HFCWC produced similar clinical effects to airway clearance techniques and was safe for non-hospitalized infants with AVB. Both techniques decreased respiratory symptoms and sharply improved SpO₂.
