Procedures Performed
Pulmonary Function Tests (PFTs)
Evaluate lung volumes, airflow, and gas exchange to help diagnose conditions such as asthma, COPD, and restrictive lung disease.
6-Minute Walk Test (6MWT)
Measures functional exercise capacity and oxygen saturation during physical activity, often used to monitor chronic lung or heart conditions.
What to Expect During Your Pulmonary Test
Pulmonary Function Test (PFT):
You will be asked to breathe into a mouthpiece connected to specialized equipment that measures how well your lungs are working. The test may include breathing in and out forcefully, inhaling medication to assess response, or sitting in a small, enclosed booth for certain measurements. The procedure is painless and typically takes 30–60 minutes.
6-Minute Walk Test (6MWT):
You will walk at your own pace along a flat corridor for six minutes while your heart rate and oxygen levels are monitored. This test helps assess your endurance and oxygen needs during activity. Wear comfortable clothing and walking shoes.
