I hate getting the low peak flow reading.. around the 'call an ambulance' stage.. I really really try and avoid it..
But peak flow is great for working out what medicine to take and how much.

most welcome my dear!!!

Be well!!!

Thanks Alskling.

I talked to my doctor about it and she pretty much had said what you did. but thanks for leaving a comment. :)

My dear crackednut,

Just saw your post dear and I thought I could help... well a peak flow meter measures the "peak" i.e. the maximum strength by which you blow, which in effect shows the strength of your lungs! measurement is also called "lung capacity" measurement.. so when you blow really strong in your peak flow meter (as probably your doctor has advised), the flow meter records your maximum strength to blow.... it is of course a spontaneous measurement ... and very much dependent on the psych of the moment and the general physical health...



as for the measurements readings maybe the scale is different to various meters... mine for instance

reads up to 600 readings and doctor said that if when i blow reading is above 200 then i should not worry short term... but if that continuous or drops below 200 then i should consult him for alternative treatment.



however please remember that a peak flow meter is only a monitoring device, not a treatment!.. you should follow your docs suggested treatment



hope it helps,

good luck,

Kisses, Harry
