i was diagnosed with copd 5 yeras ago. i am 63 and i had a lung function test at that time. after 46 byears of smoking i quit smoking and vape on ecigs now. my LFT 5 years ago showed 30% good lung capacity and i repeated thye test a year later. that exam also showed i had 30% lung funtion remaining. with me knowing that 29% meant i would be in stage 4 or end stage and i refused to go in again for the last 3 years. i have great medical benefits with the VA. i am a 100% disabled vietnam veteran. i take symbacort, spiriva, and ibuteral daily. i am now on home oxygen as of last week, following an assault where i suffered 3 fractured verteba and community acquired puneumonia. do you think i should have another lung function test, even tho i ewally dont want to know whqat i assume will be shown that i have stage 4. afterall, all i have needed for the last 5 vyears is, as you know is to drop just 1 point to 29%

thank you
