Anxious about COPD concerns while awaiting pulmonary function tests

[Nora.R]

My pulmonologist has ordered a full series of pulmonary function tests to investigate my persistent shortness of breath and chronic cough, which hasn't improved with standard asthma treatments. I'm a former smoker in my fifties, and I'm quite anxious about what the PFT results might reveal, especially the possibility of COPD. For others who have undergone this testing, what was the experience like, and how did you manage the anxiety leading up to it? How detailed were the results in helping you and your doctor pinpoint a specific diagnosis, and what kind of follow-up questions should I be prepared to ask once I receive the interpretation from the specialist?

You're not alone—PFTs can be anxiety-provoking, especially with COPD on your mind. In practice, the tests measure how well your lungs move air and how they exchange gases, and most people get a clear briefing with plain-language results afterward. If you can, bring a support person for the discussion and ask the tech to explain what each step means.

What typically happens during a PFT: first, spirometry to measure FEV1 and FVC and the FEV1/FVC ratio; sometimes body plethysmography for lung volumes; and a DLCO test to gauge gas exchange. A bronchodilator maneuver may be done to test reversibility. A COPD pattern usually shows reduced FEV1/FVC not fully correcting after bronchodilation, while restrictive patterns lower lung volumes with a normal or high ratio; DLCO can help distinguish causes somewhat. Your physician can interpret in the context of your smoking history.

Anxiety-management tips before the test: arrange a support person if allowed, practice slow breathing (inhale 4 seconds, exhale 6), avoid heavy meals and excess caffeine beforehand, and ask the staff to walk you through each step so you know what to expect. If you feel overwhelmed, it’s okay to pause and resume when you’re ready. A short post-test stroll can also help you decompress.

Post-test questions you might bring to the specialist: What’s the most likely diagnosis based on these results? What other tests would confirm it (CT chest, bronchoscopy, bloodwork)? How will this change treatment or lifestyle recommendations? What’s the prognosis and typical monitoring plan? Are there thresholds that would prompt urgent care, and when should I follow up with you? How does smoking status alter management and can you connect me with rehab or cessation resources?

If COPD or another condition is suspected, plan how you’ll manage: smoking cessation support, vaccines (flu and pneumococcal), and a potential referral to a pulmonary rehabilitation program. If results are inconclusive, discuss next steps like additional imaging or specialist follow-up. Either way, ask for a patient-friendly summary of the findings and a written plan with clear milestones and follow-up dates.
