Pulmonary Function Testing

About the  Pulmonary Function Testing Laboratory:

The Pulmonary Function Testing Laboratory, a part of Respiratory Care Services, uses routine and sophisticated diagnostic services to guide therapeutic and management decisions for patients with lung disorders. Pulmonary function tests measure how well the lungs take in and release air, and how well they move oxygen from the atmosphere into the body’s circulation.

Licensed and board-certified respiratory care personnel trained and experienced in pulmonary function testing and technology carry out the day-to-day operations of the PFT Lab.

How to Prepare for the Tests

Do not eat a heavy meal, and do not smoke for 4 – 6 hours before testing. You’ll get specific instructions on whether you need to stop using bronchodilators or inhaler medications. You may have to breathe in medication before your test.

How the Tests Will Feel

Since the tests involve forced and rapid breathing, you may have some temporary shortness of breath or lightheadedness. You will breathe through a tight-fitting mouthpiece, and you’ll have nose clips.
