Figure 1

Lung compliance and chest radiographs. The line graph shows improvement in lung compliance as calculated by the mechanical ventilator. Lung compliance was temporarily compromised with interventions such as lavage or surfactant administration; however, it subsequently recovered to adequate levels. Parallel with recovery of lung compliance, the radiolucency of the lung gradually improved. a) Day 11. b) Day 12 before lavage and hematoma removal. c) Day 13 before surfactant administration. d) Day 15.
