Figure 1. Images from a CT scan of the chest of the incident patient with dynamic evaluation of the airways at 3 months of age before closure of the ductus arteriosus. There was a minimum transverse area of 25.2 mm2 (A) and a maximum transverse area of 33.2 mm2; (B) of the lower trachea with a positive end-expiratory pressure of 4 cm H2O. There was a minimum transverse area of 30.3 mm2; (C) and a maximum transverse area of 47.3 mm2; (D) of the lower trachea with a positive end-expiratory pressure of 12 cm H2O.
