Hi Everyone,
I had my 2024 PFT last week. I was wondering if anyone can help me compare these results with my previous tests. Note: The doctor is only allowed 10-15 minutes per patient to go over the results, answer questions and write Rx’s. My spirometry section looks reasonably stable (FVC, FEV1, FEV1/FVC) except for my FEF75/25 which I understand can vary widely. What I need is some help understanding the Lung Volume and Diffusion Capacity sections.
Lung Volumes:
RV: 96% (2018), 137% (2022), 84% (2024) - 2 of the 3 test fall within the normal range and one indicates air trapping. Any feedback?
FRC: 91% (2018), 97% (2022), 63% (2024) - Big drop?
RV/ TLC: 100% (2018), 126% (2022), 101% (2024)
Diffusion Capacity:
DLCO_ SB: 93% (2018), 96% (2022), 80% (2024) Is this a large drop?
My doctor agrees that this is probably early or pre-COPD but did not have time to go over my full report. Any insights on my Lung Volume and Diffusion sections as well as my overall progression?
Thank you for your time and consideration!!
