Figure 1.

Gas exchange(Pa_O2) and lung function (C_dyn). Time course of Pa_O2 (left panel) and dynamic compliance (C_dyn; right panel) over the observation period. Induction of lung injury by repetitive lavage procedures (T = 0) is followed by open lung concept positive pressure ventilation (PPVOLC; n = 5) or surfactant treatment under conventional positive pressure ventilation with a modified monomeric surfactant protein B surfactant (mon SP-B; n = 4) or a natural bovine surfactant (Alveofact^®; nat SF; n = 4). Results are given as mean and standard deviation.
