I was recently diagnosed with asthma. It was a surprise because I don't have a wheeze. Anyway, I'm a bit confused about 'normal' peak flow. Apparently, 440 is normal for my age (27) and height (165cm). Prior to starting treatment, I was blowing about 150 and now I'm averaging about 280-300. I'm not due a review for another week. I'm not sure about if I'm aiming for 440 or if I'm doing ok? I still feel really short of breath. However, I have Rheumatoid Arthritis and my consultant is a bit concerned that I have an underlying Rheumatoid related lung disease. I'm waiting for further tests.
Thanks in advance.
