Lung Function Testing

Lung function testing, also called pulmonary function testing (PFT), helps assess how well your lungs are working. These tests are essential for diagnosing and managing conditions such as asthma, COPD, and other respiratory concerns. The testing measures lung volume, airflow, and gas exchange to provide a detailed view of your pulmonary health. Patients breathe into a device that records data used by healthcare providers to identify patterns of obstruction or restriction.

The process involves using a spirometer or other devices to capture how much air you can inhale and exhale, and how fast. Some tests may involve sitting inside a small chamber, while others use handheld tools. Measurements such as FEV1 and FVC provide data on the capacity and efficiency of your lungs. The results are compared to expected values based on your age, height, gender, and ethnicity.
