Comparison of Mask-NIV with low inspiratory effort and HNFC or CPAP with moderate inspiratory effort. Even when dividing by two the inspiratory effort, the tidal volume generated with the use of NIV conducted with an oro-nasal mask (Mask-NIV) remained largely higher than the tidal volumes observed with the use of high-flow oxygen through nasal cannula (HFNC) or continuous positive airway pressure (CPAP). * denotes p < 0.05 vs. mask NIV. Pmus: inspiratory muscle pressure
