PFT
About PFT
Pulmonary Function Test (PFT) Services at Nano Hospitals are specialized diagnostic tests used to evaluate how well the lungs are working. These tests measure lung capacity, airflow, and gas exchange to help diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, and other breathing disorders.
PFT plays a vital role in assessing lung health, guiding treatment, and tracking response to respiratory therapies.
Overview
Pulmonary Function Tests are a group of non-invasive breathing tests that assess how efficiently the lungs inhale, exhale, and transfer oxygen into the blood. The most common component is spirometry, which measures airflow and lung volume.
At Nano Hospitals, PFT services are conducted using advanced computerized systems that provide accurate and detailed reports for respiratory evaluation.
Workflow
- Step 1: Medical Evaluation A doctor recommends PFT if a patient has chronic cough, breathlessness, wheezing, or requires monitoring of a known lung condition.
- Step 2: Test Preparation The patient is guided on proper breathing techniques. Tight clothing and heavy meals are usually avoided before testing.
- Step 3: Spirometry Testing The patient breathes into a mouthpiece connected to a spirometer, following instructions to inhale and exhale forcefully.
- Step 4: Additional Lung Measurements Depending on the requirement, lung volumes and diffusion capacity tests may also be performed.
- Step 5: Analysis and Reporting Results are analysed by specialists to identify airflow limitation, lung restriction, or gas exchange problems.
Benefits & Value
For Patients
- Early detection of lung diseases
- Better management of asthma and COPD
- Monitoring of treatment response and disease progression
For Doctors
- Objective assessment of lung function
- Helps differentiate between obstructive and restrictive lung disease
- Guides medication adjustments and therapy plans
For the Community
- Improved awareness and screening of respiratory diseases
- Better long-term management of chronic lung conditions
- Reduced hospitalizations due to early intervention
Risks & Challenges
- Temporary dizziness or shortness of breath during forceful breathing
- May be difficult for very elderly or severely breathless patients
- Requires patient cooperation for accurate results
- Not suitable during acute severe respiratory distress
