How is a collapsed lung diagnosed?

Your healthcare provider will ask about your history of lung disease and perform a physical exam. They may also measure the level of certain gases in your bloodstream. To measure gases like oxygen and carbon dioxide, a technician collects a blood sample and analyzes it in a lab.

The most common way to diagnose a collapsed lung is with medical imaging. Usually, you’ll have a chest X-ray. But you may have a CT scan or ultrasound.
