Pulmonary Function Test (PFT)

What it is

The most common PFT is spirometry. You breathe into a mouthpiece connected to a machine and follow the technician's instructions to breathe in fully and blow out as hard and long as you can. The machine records the volumes and flow rates.

Why it may be recommended

A PFT may be advised to help evaluate breathing-related symptoms, to monitor a known respiratory condition, to check lung function before certain work roles, or as part of a comprehensive or insurance medical examination.

What patients can expect

The test involves repeated breathing efforts and usually takes around 15–30 minutes. It requires effort and cooperation, and the technician will coach you through each attempt. You may be asked to repeat efforts to get consistent readings.
