1 Lung model expiratory CO2 (or PETOv2) representing simulated alveolar CO2 at baseline (no high-flow nasal cannula) and effect on expiratory CO2 at different flows provided with the Optiflow and Precision Flow high-flow nasal cannula systems. Lung model expiratory CO2 (or PETOv2) representing simulated alveolar CO2 at baseline (no high-flow nasal cannula) and effect on expiratory CO2 at different flows provided with the Optiflow and Precision Flow high-flow nasal cannula systems. Individual data points are shown for each measurement of CO2, fitted with locally weighted scatterplot smoothing curves. Gray vertical lines represent the change point where a nonlinear relationship between flow and expiratory CO2 was observed. There was no change point observed in expiratory CO2 in adult and term newborn models. Katie R Nielsen et al. Respir Care 2018;63: (c) 2012 by Daedalus Enterprises, Inc.
