Fig. 3From: Tracing exogenous surfactant in vivo in rabbits by the natural variation of 13CEstimated contribution of exogenous surfactant. Ratio between exogenous and endogenous DSPC (mg/kg) in the alveolar pool of rabbits treated with different doses of poractant alfa by InSurE. Data shown as mean. Standard deviation bars refer to the total amount of DSPC. Kendall’s correlation for the exogenous surfactant dose: τb = 0.710, p < 0.0001Back to article page
