If significant respiratory / cardiac symptoms are present or continue, consider referral to a respiratory specialist / pulmonologist and / or a cardiologist for an opinion and consideration of the following: |
 • Repeat routine lung function tests (spirometry, diffusing capacity). |
 • Static lung volumes. |
 • Percutaneous oxygen saturation or arterial blood gas analysis, as indicated. |
 • Appropriate radiology, for example, chest X-ray, high resolution lung scan (HRCT chest). |
 • Respiratory orientated exercise test or screen with six-minute walk test. |
 • Respiratory muscle strength testing. |
 • Bronchial provocation (methacholine, mannitol or other agent) testing. |
 • Blood tests as clinically indicated. |
 • Specific cardiac function tests as appropriate. |
 • Exercise testing with oxygen saturation or blood gas analysis. |
