Hello all. My name is Brent A. from California. I will be 69 years young in three weeks time. I was recently diagnosed COPD favoring emphysema on Feb.23, 2023 due to an increasing cough and mucus production (10-15 mls per day). My numbers are: FEV1 54% stage 2-3. FVC is normal. Flow volume loop shows evidence of obstructive contour..Total Lung Capacity and Residual Volume show evidence of hyperinflation. Diffusion capacity is reduced at 68%. Lack of bronchodialator response favors COPD/emphysema. I am surprised with my diagnoses and low FEV as I strenuously walk three miles a day and at the top of my walk (1 1/2 mile uphill) my finger oxymeter reads 96-97% and rebounds to my usual 98-99% in 20-30 seconds that I maintain during the day.I have and appointment with a pulmonary Doctor next week. Your thoughts on questions for the Doctor? ManyThanks! See ya around!
