I had an arterial blood gas test back in August and was told that the results were "Normal" and never received a copy. However, in light of multiple failed PFT tests which show my breathing at an average of 70% of normal and several doctors interpreting them as having a probable restrictive lung/airway disease, I requested a copy of the arterial blood gas test which was faxed to me today. My absolute #1 symptom is shortness of breath and I am trying to get oxygen which my insurance will not cover (just to try it in a bad episode at home, knowing that it may not help me.) Whether my shortness of breath is ultimately due to autonomic causes, mast cell issues, mold/toxin exposure, or some other cause remains to be discovered but a high resolution CT scan of my lungs was normal. Two items were flagged on my ABG test, the "BE" or base excess and the "P02" which I believe means the "partial pressure of oxygen" from my Google search. I am wondering if anyone else has had this test or understands these terms that could explain it to me so I can try to interpret my results. Per my doctor they are normal but per the lab, they were flagged as abnormal and are outside of the lab ranges so I am very curious how they fit with my total picture. Any info is very much appreciated.
