Fig. 2From: Asymmetrical high-flow nasal cannula performs similarly to standard interface in patients with acute hypoxemic post-extubation respiratory failure: a pilot studyElectrical impedance tomography during standard and asymmetrical HFNC oxygen therapy. Variables are expressed as median, with an interquartile range [IQR]. Additional data are reported in Fig. S1. A: global lung aeration; B: lung aeration in dependent area; C: lung aeration in non-dependent area. Abbreviations: ns not significant, HFNC high-flow nasal cannula, dep dependent, non-dep non-dependent, EELI end-expiratory lung impedance (measured as percent change from VM)Back to article page
