Morning all I just wondered if anyone can shed on light on this for me? I have been studying my peakflow in readiness for a visit to a consultant. What I have noticed is that my peakflow can be as high as 360 and yet I still need to use my blue inhaler 8 times. However over the past few days it has been as low as 300 and I haven't struggled to breath and haven't needed to use the blue inhaler once! Has anyone else had this same experience? I am really confused now as the peakflow isn't going to be accurate to how I feel!
