Pulmonary function tests (PFTs) are the gold standard for measuring lung health. Understanding them helps you have informed conversations with your physician about your respiratory status.
You blow into a device that measures FEV1 (forced expiratory volume in 1 second) and FVC (forced vital capacity). The ratio of FEV1/FVC indicates whether there is airflow obstruction. Below 70% suggests obstructive disease.
Adults over 40 with a smoking history, anyone with persistent respiratory symptoms, and people with occupational exposure to dust, fumes or chemicals. Testing is non-invasive, takes about 15 minutes and provides objective data.
PFTs measure what matters. Lungora provides nutritional support, but only PFTs tell you how your lungs are actually performing. If you are taking any respiratory supplement, baseline and follow-up PFTs provide objective accountability.
