Lung Function Test

Lung Function Test is a Spirometry Test involving breathing into a mouthpiece, which is connected to a machine via some tubing. You will be required to breathe in and out as deeply as possible, and then as fast and as forcefully as possible. The test may make you feel temporarily short of breath. To measure diffusion capacity (Gas Transfer), you breathe a harmless gas for a very short time. The concentration of the gas in the air you breathe out is measured. The difference in the amount of gas inhaled and exhaled measures how effectively gas travels from the lungs into the blood. If possible do not take Ventolin, Asmol, Bricanyl, Bretaris, Brezhaer for 4 hours, Spiriva, Atrovent, Onbrez for 6 hours and Pulmicort, Serevent, Symbicort, Seretide, Flixotide, Oxis, Alvesco, Salmeterol, Beclomethasone, Flutiform, Breo ‐ Ellipta for 12 hours before the test. Do not smoke 6 hours beforehand. (Approximately 30 minutes)
