Pulse oximetry tracing: resting up to time 0, supine time 0-1.8 minutes, seated 1.8-4 minutes, and during a well tolerated 200 m walk 4-8 minutes.

Oxygen saturation by pulse oximeter was 96% on room air at rest, 93-94% after a well tolerated 200 m walk, and less than 80% after less than 2 min supine (Fig. 1).
Inspiratory chest radiograph at the time of initial presentation shows small lung volumes and some areas of sub-segmental atelectasis and bilateral elevation of the hemi-diaphragms to the level of the fourth anterior ribs.

The patient's chest radiograph demonstrated small lung volumes, sub-segmental atelectasis and elevation of both hemi-diaphragms (Fig. 2).
Inspiratory chest radiograph 4 years later demonstrates normal lung volumes compared with previous: the hemi-diaphragms are now at the level of the sixth anterior ribs.

His follow-up chest radiograph demonstrated radiographic improvement with increased lung volumes, now normal) compared to his previous (Fig. 3).
