What does it mean The FVC, FEVI, FEVI/FVC ratio and FEF25-75% are within normal limits. The airway resistance is normal. The reduced diffusing capacity indicates a minimal loss of functional alveolar capillary surface. However, the diffusing capacity was not corrected for the patient's hemoglobin.
Conclusion: The diffusion defect is consistent with a pulmonary vascular process. Anemia cannot be excluded as a potential cause of the diffusion defect without correcting the observed diffusing capacity capacity for hemoglobin.
Pulmonary function diagnosis: Minimal diffusion defect= Pulmonary vascular
Diffusion defect is a finding on spirometry. Diffusion defect is any impairment in the diffusion of oxygen across the alveolar-capillary membrane. Diffusion defect is considered present when the % predicted diffusion is less than 75%. In the report it states that there is a problem in the pulmonary vasculature, could be thickening of the walls, which is causing the minimal diffusion defect. Please discuss this with your doctor am sure he will provide further assistance.
