So for the last month or so my peak flow has been always in the yellow zone and usually at the bottom end of that. Also often in the red zone. But ive rarepy jad my life threatening symptoms more just the annoying type of being permanentpy tight chested and getting sob or wheezy easier than usual.
So I dont consider the readings to be reflecting thw truth of the level of help or meds i would need at that time.
So does anyone know if peak flpw personal best and therefore zones can change up or down over time? Will be talking to my gp about this on monday anyway. My lung cons thought i could be getting unreliable peak flpw due to reflux and/or VCD.
Anyone had this happen?
