What is a PFT?
A Pulmonary Function Test (PFT) measures how well your lungs work. It assesses lung volume, capacity, rates of flow, and gas exchange.
Key Values Explained
- FVC (Forced Vital Capacity): The total amount of air you can exhale forcefully
- FEV1 (Forced Expiratory Volume in 1 second): How much air you can exhale in the first second
- FEV1/FVC Ratio: Used to classify obstructive vs restrictive patterns
- DLCO: Measures how well oxygen passes from your lungs into your blood
