I live in Canada and we have wildfires leading to smoke where I live .
Does anybody know how much fev1 can decline after breathing wildfire smoke ? I had a lung function test but the air quality was poor and I was walking outside before getting the test done . I had even had an exacerbation right before my test . My test results were lower than expected for my fev1 . I wonder if it was due to the wildfire smoke and I should request a new test on a day when air quality is normal . The smoke comes and goes here and is not daily . Thank you kindly .
