The Care Pathway
1. Preparation
You're advised on any inhalers to pause before the test.
2. Testing
You breathe into a device that measures lung volumes and airflow, with a technician guiding you through it.
3. Analysis
Results are compared with expected values for your age, height and sex.
4. Review
Your pulmonologist explains the results and how they guide your treatment plan.
“Your care team supports you through every stage, from evaluation to recovery and follow-up.”
Expected Benefits and Possible Risks
PFT provides essential information for diagnosis and treatment planning with minimal discomfort. There is no significant risk associated with the test.
Every treatment has potential risks. Your care team will discuss your individual risks before treatment.
