I went to the doctors today about some infection in my ear, While I was there I told him I was a little concerned about my recent lung function test as it was 66%, a year ago it was 88% (this was done using the spirometer in the nurses station) What puzzled me was that she only took one reading ( I only had to blow into the tube once) I thought you had to have three readings.
Anyway to cut a long story short, last year I also had a test where I had to blow as hard and as fast asI could into this portable cylinder type thing, the reading was 245 ( whatever that means, Today my doc told me to repeat this test there and then and the reading was 378.
I haven't a clue what any of this means, is my todays reading of 378 better than last years reading of 245 ?
Sorry to ask, but I am totally oblivious as to what these reading mean. My GP said I was fine so I just left it at that.
