Fig. 2. The difference (I) between tidal volume measured by pneumotachograph (VT,) and tidal volume estimated by probe device (VT,) against the average (I) of these two values. A horizontal line is drawn at zero difference for reference. Lines for the mean and 2SD range (95%) of the difference are shown. The trend of points is down to the right, except for the outlier, indicating that bias may increase with tidal volume.
