Pulmonary Function Tests On hold

About the service

The Pulmonary function service offers a range of respiratory tests for inpatients and outpatients from many disciplines, and direct GP referrals.

The patient performs a number of complex respiratory manoeuvres on specialised equipment. The respiratory scientist will explain the procedure to the patient and guide them through the tests. The patient must be able to understand and follow instruction.

Pulmonary function tests are a series of non-invasive breathing tests that measure how well the lung is working. Tests are performed while sitting, breathing through a mouthpiece and you also wear a noseclip to stop any air escaping via your nose. Most routine tests may take approx 30-60mins and include some of the following tests.
