Fig. 5From: Bedside monitoring of lung volume available for gas exchangeVolume changes (ΔVPaO2 and ΔVCT) in the control animals (a, b), and in the saline lavage lung injury model (c, d). Individual points represent a paired set of measurements and different colours represent changes associated with different ΔPEEP in each animal. a, c Black solid lines are the regression lines, and blue lines are the identity lines. b, d The stronger the agreement between two measurements, the closer the data are to the horizontal line (0°). b, d Blue lines are the mean angular bias, and red lines are the upper and lower limits of agreement; good concordance is assumed to be within ± 30° of the horizontal zero line.
