Computerized PFT, Spirometry & DLCO Diffusion Lab
Advanced computerized spirometry measuring lung volumes, airway resistance, and gas diffusion capacity (DLCO) for precise staging of asthma, COPD, and pulmonary fibrosis.
Procedure Overview & Clinical Purpose
Pulmonary Function Testing (PFT) with DLCO gas diffusion is an essential non-invasive diagnostic battery that quantifies lung mechanics, airway obstruction reversibility, and gas exchange efficiency across alveolar-capillary membranes. It is crucial for distinguishing Asthma from COPD and monitoring treatment response in Interstitial Lung Diseases (ILD).
Key Patient Candidates & Symptoms
What Happens During the Procedure?
Nose Clip & Mouthpiece Setup
Soft nose clip is placed and sterile bacterial filter mouthpiece is positioned between lips.
Baseline Spirometry Maneuver
Patient takes maximum inhalation followed by forceful, rapid blast exhalation for 6 seconds.
Bronchodilator Reversibility Test
A rapid-acting bronchodilator puff is administered, and test is repeated after 15 mins to check reversibility.
DLCO Single-Breath Gas Diffusion
Single breath-hold maneuver calculates exact carbon monoxide diffusion capacity across lung membranes.
How to Prepare Before Coming to the Hospital
- Hold short-acting relief inhalers (Levolin/Asthalin) for 4-6 hours before testing if advised
- Avoid smoking or heavy meals for 2 hours prior to the test
- Wear loose-fitting comfortable clothing around chest and waist
