Pulmonary Function Test

A pulmonary function test (PFT) is a non-invasive procedure used to evaluate lung function and diagnose respiratory conditions. It measures how well your lungs work by assessing various parameters, such as the amount of air you can inhale and exhale, how quickly you can exhale, and how efficiently your lungs exchange oxygen and carbon dioxide.


Key components of a PFT include:

  1. Spirometry: This measures the amount of air you can inhale or exhale and how quickly you can do so. It helps detect conditions like asthma, chronic obstructive pulmonary disease (COPD), or restrictive lung diseases.

  2. Lung Volume Measurement: This assesses the total capacity of your lungs and how much air remains after a maximal exhalation. It aids in diagnosing conditions that affect lung volume, such as interstitial lung diseases.

  3. Gas Exchange Measurement: This evaluates how effectively your lungs transfer oxygen into your bloodstream and remove carbon dioxide. It's useful in assessing conditions like emphysema or pulmonary vascular diseases.


Scheduling a pulmonary function test with our specialized team can be beneficial for several reasons:

  1. Accurate Diagnosis: Our board-certified allergist uses state-of-the-art equipment to conduct precise and comprehensive PFTs, aiding in the accurate diagnosis of various lung conditions.

  2. Early Detection: PFTs can detect lung problems even before symptoms become apparent, allowing for early intervention and better management of respiratory conditions.

  3. Customized Treatment Plans: Based on the test results, our team can create personalized treatment plans tailored to your specific lung health needs, whether it involves medication, lifestyle adjustments, or other interventions.

  4. Monitoring Lung Health: Regular PFTs can help monitor the progression of lung diseases and the effectiveness of ongoing treatments.
