PFT stands for Pulmonary Function Test. It is a type of medical examination performed to assess the function and capacity of the lungs. PFTs are commonly conducted by healthcare professionals, such as pulmonologists or respiratory therapists, to evaluate lung health, diagnose respiratory conditions, monitor the progression of diseases, and determine the effectiveness of treatments.

During a PFT, various measurements are taken to evaluate different aspects of lung function. Some of the commonly measured parameters include:

Spirometry: This test assesses lung capacity and airflow by measuring how much air a person can inhale and exhale forcefully and how quickly they can do it. It helps diagnose conditions like asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases.

Lung Volume Measurements: These tests measure the total volume of air in the lungs, including the maximum amount of air a person can inhale or exhale. They provide information about lung capacity and can help diagnose conditions such as pulmonary fibrosis or emphysema.

Diffusion Capacity: This test evaluates how well the lungs transfer oxygen from the air into the bloodstream. It is useful in diagnosing conditions affecting the lung tissue, such as interstitial lung disease.

Peak Expiratory Flow (PEF): PEF measurement determines how fast a person can exhale forcefully and is often used to monitor asthma or assess the severity of an asthma attack.

PFTs are essential in diagnosing and monitoring respiratory conditions, as they provide valuable information about lung function, detect abnormalities, and help healthcare professionals tailor appropriate treatment plans. The results obtained from PFTs assist in assessing the effectiveness of medications, tracking disease progression, and making informed decisions regarding the management of respiratory disorders.
