Intro

• PFT: COPD and asthma
• CXR: lung and pleural disorder
• Labs: anemia, thyroid disorder, and heart failure

Protocol

• Move from tier 1 to 2 then to 3 if no clear diagnosis
• Stop at any tier if there's clear diagnosis
• tier 2 does not include echo
• if CPET points to cardiac: echo or stress echo
• Tier 3: Other organ focused testing includes chest CT, bronchoscopy, echo, nuclear stress, RHC based on previous results.
• Normal Tier 1 and 2 study suggest dyspnea is non-cardiorespiratory, and Tier 3 studies were not necessary¹
