PFTs (Pulmonary Function Tests)

Pulmonary Function Tests (PFTs) are diagnostic tools that measure how well your lungs work. They assess how much air you can inhale and exhale, how efficiently oxygen enters your blood, and how well your lungs transfer gases. These tests help diagnose conditions like asthma, COPD, and other lung diseases, evaluate their severity, and monitor treatment effectiveness. Usually performed with breathing into a machine, PFTs provide essential information about lung capacity, airflow, and overall respiratory health.
