Milési C, Requirand A, Douillard A, et al. - Researchers conducted this prospective study to evaluate the inspiratory demand in young infants with acute viral bronchiolitis, in order to provide a physiological basis for initial flow setting for patients supported with high flow nasal cannula (HFNC). The sample consisted of 44 infants up to 6 months old with AVB, admitted to a pediatric intensive care unit from November 2017 to March 2019. According to findings, HFNC therapy is widely used to support infants with AVB. The efficiency of the device is optimal if the flow setting matches the inspiratory demand of the patient. In most situations, a flow rate of < 2.5 L/kg/min would be appropriate.
