What is a pulmonary function test?
A pulmonary function test (PFT) evaluates lung function by measuring the amount of air your lungs hold and how fast the air enters and exits the respiratory system. Patients will blow into a mouth piece as a machine measures the flow of air based and compares your values to normal controls.
What diseases does pulmonary function help diagnose?
Pulmonary function testing evaluates for restrictive or obstructive lung conditions and at Avant Allergy, Dr. Sandra A. Ho uses PFTs to diagnose and monitor response to treatment for asthma.
