PFT (Pulmonary Function Test)

Overview Understanding Clinical Use Key Features What to Expect Advantages Connect with us FAQs

Overview

Overview

Pulmonary function tests (PFTs) are a battery of tests that measure how well a patient's lungs work. They are non-invasive tests that assess lung volume, capacity, rates of flow, and gas exchange. Additionally, PFTs provide important information about the severity, nature, and progression of lung diseases such as asthma, pulmonary fibrosis, cystic fibrosis, COPD or interstitial lung disease.

At Heritage Hospital, we pride ourselves on utilizing advanced PFT technologies to provide accurate diagnoses. We prioritize patient comfort in our best PFT test in Varanasi and ensure reliable diagnostics for all respiratory conditions.

Understanding

PFTs evaluate lung size, airflow, lung volume, and gas exchange efficiency to detect any restrictions or deficiencies in respiratory health. Two main methods are used to assess pulmonary function test in Varanasi:

  1. Spirometry: It uses a mouthpiece device hooked to an electronic spirometer to record the volume and flow of inhaled and exhaled air through various breathing manuevers. Parameters like tidal volume, minute volume and vital capacity are measured.

  2. Plethysmography: It requires sitting inside an airtight box while performing the required breathing tasks. The changes in pressure signals are used to derive key lung volumes like residual volume and total lung capacity.

The other common Pulmonary Function Tests are:

  • Lung Volume Tests: It measures lung capacity, or the volume of air in the lungs, during different phases of breathing.

  • Diffusing Capacity for Carbon Monoxide (DLCO) Test: This test measures how well gases transfer from the lungs to the bloodstream.

  • Peak Flow Test: It measures how fast air can be forcefully exhaled. This is useful for monitoring and managing conditions such as asthma.

This information helps clinicians diagnose and decide the treatment course for various lung disorders. At Heritage Hospital, PFTs are performed by certified respiratory therapists in the Chest and Respiratory Diseases department under the supervision of our best respiratory doctor in Varanasi and his team of pulmonologists.

Clinical Applications of PFT (Pulmonary Function Test)

Clinical Applications of PFT (Pulmonary Function Test)

At Heritage Hospital, pulmonologists use the best lung function test in Varanasi for various clinical applications related to respiratory health:

  • Diagnosing Respiratory Conditions: PFTs are instrumental in accurately diagnosing various lung conditions like asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and other respiratory disorders.

  • Monitoring Disease Progression: For patients already diagnosed with lung diseases like COPD or pulmonary fibrosis, regular PFTs allow our pulmonologists to track any decline in lung function over time closely. Repeating the PFTs at intervals helps gauge disease progression and severity.

  • Pre-Surgical Assessment: PFTs are routinely conducted before major surgical procedures, especially in patients with diagnosed respiratory illnesses. They allow assessment of the patient's baseline lung function prior to surgery.

Procedure

Patients scheduled for PFT in Varanasi are advised the following points to get the most accurate results:

  • Avoid vigorous exercise within 30 minutes before the test.

  • Refrain from smoking at least 24 hours prior to testing.

  • Avoid large meals for 2-3 hours before testing.

  • Wear loose, comfortable clothing.

  • Inform the doctor about any medications being taken. Avoid taking bronchodilators or inhaler medications unless instructed otherwise.

  • Remove dentures if they affect the ability to seal lips around the mouthpiece.

The best lungs specialist in Varanasi at Heritage Hospital will coach patients throughout the testing, ensuring they understand the necessary maneuvers and achieve optimal results.

Post Procedure

The spirometer records the volume of air exhaled and produces a graph called a spirogram for analysis and interpretation by pulmonologists in Varanasi. Some of the key aspects of the lung function measured are:

  • Forced Vital Capacity (FVC): The total amount of air forcefully exhaled after taking the deepest breath possible. This measures the lung capacity.

  • Forced Expiratory Volume Over One Second (FEV1): The total amount of air forcefully exhaled in the first second. This measures how fast air flows out of the lungs.

  • FEV1/FVC Ratio: Indicates the percentage of the vital capacity exhaled within the first second. A lower ratio generally indicates an obstructive lung disease such as asthma or COPD.

  • A high FVC indicates large, healthy lungs. However, low FVC indicates restricted breathing and reduced lung capacity due to respiratory disorders or other medical conditions.

  • Normal value predictions based on attributes such as height, weight, gender, age and race are used for accurate interpretation. The patient's results are compared with the expected normal values for their profile and expressed as a percentage.

PFT reference values at Heritage Hospital are from recent recommendations that use data from a healthy multi-ethnic population to be more representative of our diverse patient demographics.

Our best lung specialist in Varanasi will determine what the PFT results mean by analyzing the type of abnormalities in values and the pattern of impairment based on medical history and symptoms.

Advantages of PFT (Pulmonary Function Test)

Non-Invasive and Safe

PFTs are completely painless and non-invasive tests that carry minimal health risks for patients. This makes them safe for use in most patients.

Early Detection

The tests can detect diminished lung capacity and airflow limitations even before obvious respiratory symptoms manifest. This helps in early diagnosis and treatment of conditions.

Personalized Treatment Plans

By objectively quantifying patients' lung function, PFTs allow pulmonologists in Varanasi to develop personalized treatment plans tailored to their impairments. Results help guide decisions regarding medication, oxygen therapy or pulmonary rehabilitation approaches.
