The results are taken from a bench experiment with inelastic orifices, and patients rarely have a closed system; however, the bench data demonstrate that a small reduction of the leak around the cannula, by occluding a larger area of the nare, may lead to a substantial increase of delivered pressure, particularly in the upper range of NHF rates. Fig. 1 The graph shows the positive airway pressure, cmH2O, that is generated by nasal high flow (NHF) using a smaller cannula (O.D. 6.1 mm) and larger cannula (O.D. 7.2 mm) in "nares" with two different diameters: 10 mm (left panel) and 9 mm (right panel) in the bench top model. Pressure generated by NHF can be increased by higher flow and by occluding a larger area of the nare, which can be achieved by increasing the cannula size	./cache/cord-346394-rk8jkf19.txt	./txt/cord-346394-rk8jkf19.txt
