The Pulmonary Function Test (PFT) is a series of breathing tests in which you will be asked to breathe through a machine to determine air flow into and out of your lungs.
This may include the Methacholine Challenge Test. This is a test in which a drug (methacholine) is given during a PFT to help diagnose asthma, and in certain circumstances assist in the management of asthma.
These tests can take from 30 to 90 minutes, depending on the extent of the testing your doctor has ordered. It cannot be performed if you haven't properly prepared for it.
Required for all tests:
Most inhalers must be held for 12 hours. However, long-acting medications (both oral and inhaled) must be held for up to 48 hours (call with specific questions).
Examples of (bronchodilators) inhalers or nebulizers to hold for all tests:
You cannot be pregnant and have the Methacholine Challenge.
In order to achieve optimal results, a non-distracted environment is required. Please plan to have as few people as possible in the room during the procedure.
Below are estimated times for each procedure.
