Lung Volume, Breathing Pattern and Ventilation Inhomogeneity in Preterm and Term Infants
Figure 5
a) Tidal volume versus weight for term and preterm infants. The black line indicates the regression line with a coefficient of correlation of 0.31 for the term-born infants and a coefficient of correlation of 0.65 for the preterm infants and the respective R2 values given in the figure. b) Variability in lung volume determined by weight depending on disease severity. The graph shows 1−R2 value of the regression model between weight and FRC. The R2 value indicates how much of the variability in lung volume can be explained by the weight, and thus the 1−R2 is a measure of how much infants are able to change their lung volumes given their body size.
