How to prepare for a PFT?
Screening is done prior to booking an appointment. Tests should be contraindicated in patients who have had a recent heart attack or stroke, recent eye or abdominal surgery, or major head injury. There is no preparation needed for the day of test itself. However, patients should avoid the following prior to testing: eating a large meal, consuming coffee, tea, or items that contain high levels of caffeine, smoking and strenuous exercise.
Pulmonary function tests are non-invasive so they are mostly safe, however, some risks include dizziness, coughing and feeling shortness of breath. Special steps are taken to lower these risks. The technician monitors the patient throughout the testing and ensures there is adequate time to rest.
