Changes in dyspnea, thirst and discomfort during the 2-h study period. Dyspnea (panel a), thirst (panel b) and discomfort (panel c) were assessed using 0–10 visual analogue scales on which 0 indicated absence of dyspnea, thirst, or discomfort and 10 signified the worst possible dyspnea, thirst, or discomfort. The open bars represent the high-flow nasal oxygen group and the gray bars the Venturi mask group
