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.
Pulmonary Function Testing Laboratory services include:
- Basic Spirometry (Forced Vital Capacity, Flow-Volume Loops, Flows)
- Pre- and Post-Bronchodilator Comparison Studies
- Lung Diffusion Capacity (DLCO)
- Lung Volume Studies (Total Lung Capacities)
- Methacholine Challenge Studies
- Pulse oximetry spot checks
- Indirect Calorimetry, including substrate utilization, for nutritional assessment
Helps physicians with these procedures:
- Diagnostic bronchoscopy
- Therapeutic bronchoscopy
- Argon Plasma Coagulation
- TGI (Transtracheal Gas Insufflation) catheter insertion, maintenance, and patient/family education
- Percutaneous tracheostomy
Prophylactic/Therapeutic Treatment of Pneunocystis carinii pneumonia (PCP)
This is the only facility in the area providing protective booth required for use of pentamidine nebulizer treatments used as prophylaxis against or treatment of PCP in immunocompromised patients.
How to Prepare for the Test
Do not eat a heavy meal, and do not smoke for 4 – 6 hours before the test. You’ll get specific instructions on whether you need to stop using bronchodilators or inhaler medications. You may have to breathe in medication before the test.
How the Test Will Feel
Since the test involves 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.
