Abstract: BACKGROUND: Although self-inflating bags are widely used for manual hyperinflation, they do not allow ventilation parameters, such as pressure or volume, to be set. We studied the ventilation performance of neonatal and pediatric self-inflating bags. METHODS: We asked 22 physiotherapists to manually hyperinflate 2 lung models (neonatal and pediatric), using self-inflating bags from 3 manufactures (Hudson, Laerdal, and JG Moriya), with flows of 0, 5, 10, and 15 L/min. A pneumotachograph recorded tidal volume (V-T), peak inspiratory pressure (PIP), peak inspiratory flow (PH), peak expiratory flow (PEF), and inspiratory time. RESULTS: The V-T, PIP, and inspiratory time delivered by the Hudson, Laerdal, and JG Moriya bags, in both neonatal and pediatric self-inflating bags, were significantly different (P < .001). The PEF and PIF delivered were different only when using the neonatal self-inflating bags (P < .001). The V-T, PIP, and PIF delivered with a flow of 0 L/min were lower than with 15 L/min (P < .05) with all the tested bags, in both the neonatal and pediatric sizes. CONCLUSIONS: The performance of the tested neonatal and pediatric bags varied by manufacturer and oxygen flow. There was an increase in V-T, PIP, and PIP related to the increase of oxygen flow from 0 L/min to 15 L/min. The neonatal bags showed higher ventilation parameters variation than the pediatric bags.
