      High-flow nasal cannula (HFNC) oxygen therapy is used to deliver an FIO2 from 0.21 to 1.0. The double-trunk mask (DTM) is a device designed to increase the FIO2 in patients with a high inspiratory flow demand. The aim of our study was to evaluate the effect of DTM in hypoxemic subjects already receiving HFNC.

    • A new formula for predicting the fraction of delivered oxygen during low-flow oxygen therapyPeer reviewedClosed access

      During O2 therapy at low flow in patients who breathe spontaneously, the fraction of delivered O2 (FDO2) is unknown. In recent years, FDO2 prediction formulas have been proposed. However, they do not take into account the effect of inspiratory flow (V̇I) on the FDO2. The aim of this study was to validate a new FDO2 prediction formula, which takes into account the V̇I and compares it with other FDO2 ...
