what is Pulmonary Hypertension?

Lung function testing

What are lung function tests and what can they show?

Lung function tests (also called breathing tests) are a series of tests that provide information about the amount of air your lungs can hold and how effectively they work.

The results of lung function tests can tell your doctor if your airways are narrower or less effective than normal.

Watch a video of someone having some lung function tests, taken from the Pulmonary Hypertension Association (PHA UK) DVD Understanding Pulmonary Hypertension – a guide to diagnosis and treatment, here.
