PFT
A Pulmonary Function Test (PFT) is a comprehensive evaluation used to measure how well the lungs are working. It assesses lung volume, capacity, rates of flow, and gas exchange. PFTs are crucial for diagnosing various respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other disorders affecting breathing. For those seeking Pulmonary Function Tests in Kharghar, the process involves the patient breathing into a mouthpiece connected to a spirometer, which records the amount and rate of air inhaled and exhaled over a specified period.
Your doctor may order these tests:
- If you’re having symptoms of lung problems
- If you’re regularly exposed to certain substances in the environment or workplace
- To monitor the course of chronic lung disease, such as asthma or chronic obstructive pulmonary disease (COPD)
- To assess how well your lungs are working before you have surgery

PFT Measures -
- SVC (Slow Vital Capacity): SVC gives a measure of the change in volume of gas in the lungs from complete inspiration to complete expiration or vice versa. The measurement begins with the subject quietly breathing in a steady-state condition followed by a maximal breath-in and a full breath-out.
- MVV (Maximum Voluntary Ventilation): The volume of gas that can be breathed in 15 seconds when a person breathes as deeply and quickly as possible. The result is extrapolated from 15 seconds to show what could be achieved over one minute. At the best of times, the MVV can be a difficult test to assess in terms of patient effort and compliance.
- FVC (Forced vital capacity): The forced vital capacity (FVC) measurement shows the amount of air a person can forcefully and quickly exhale after taking a deep breath. Determining your FVC helps your doctor diagnose a chronic lung disease, monitor the disease over time and understand the severity of the condition.
