Monitoring

Patients are initially monitored weekly, then monthly. Monitoring includes respiratory symptoms, chest x-rays, high-resolution chest computed tomography (HRCT) scans, and pulmonary function tests (including vital capacity and diffusing capacity, and oxygen desaturation during a walk in the hall or climbing stairs, or during the formal 6-minute walk test). A chest HRCT scan should be obtained for new-onset symptoms such as shortness of breath.
