Hi everyone.. i am 45 yr old male x smoker. I am new to this forum. I went to see a lung specialist because I was having sob and was given a Spirometry test and Dr said my fvc 81% FEV1 75% and my FEV1/fvc ratio was 75.6% I am confused. what does this mean?? He gave me 2 inhalers and told me to use them to see I feel better. Do I have COPD ?? He also mentioned something about DLCO was normal. Thanks guys any info would be great.
