Whats your peak flow?

Just wondered what everyone's normal peak flow is?

My all time personal record is 550, with a usual score of 480ish when under control. The last week or so, its been in the 300's.

I have no idea what the ""normal"" range is although I guess that it all varies per individual. Would be interested to hear from you!

Thanks

My best score is 550 but haven't seen that for a while!

Not sure there really is a 'u shud b' norm

but u can get a chart online that gives an average guide, based on height and age.

Your peak flow all dapends on your sex,age, height and technique.This should be put in your plan when diagnosed so you have something to go against. It should also be revieved annually as we dont always get whats predicted. My predicted is 500 but i havent got above 200 for three years, because im brittle and unstable. A and E departments make a fuss but im lucky that its in my notes that doing peak flows actually makes me worse as makes me cough alot!!and arent of much importance when so bad.

I've done about 450 before, normally average around 380 - 400 when feeling good, currently around 300 max and has been for a while now.

According to the EU scale mine should be 409. I supose I am pretty good as my ""norm"" is 350 - I am yet to beat 380.

hi all

my predicted is 470, on a good day i get between 380 and 430, average 350,

i have a piko 1 which i find quite helpfull as i was often finding my PEFR ok but felt tight and couldn't understand it , now if i feel tight with normal ish PEFR my FEV1 tends to be low, i find this reassuring as i was beginning to wonder if i was imagining how tight i was.

you need to go what is 'normal' for you not anyone else. i usually start to pay attention to it if it dips below 20% of my average.

My predicted is around 470 but I frequently get around 540 - 550, my best is 570 and that's on the old scale not the new EU but my peak flow doesn't really change when i have problems, it may dip to around 480 if i've got a cold or virus, so have to go on how i'm feeling.

When I was 16 my best peak flow was 570 but now at 32 my best is 300, though most of the time I run at about 200. This morning it was 90, which isn't too great, but I'm only a week out of hospital so things are still failry unstable.

Hi my best at mo is about 420 but am hovering around 370-380 at mo tho when I have eitgher been gym or played clarinet or had a hard day it tends to dip to around 350 even with ventolin. Guess I will give up.

My beat at moment is 250 pre which then goes up to 300 which is way below what it was a year ago today 250 at least not as low as it was 2 weeks ago at 160

my expected is supposed to be 465l/min but ive never got upto my personal best of 370 l/min, (must have been a very good day that day), nowadays it usually stays quite low at 330-250, but during attacks it can go straight down to 190-220.

My best is 440 but coasting around 370 at the moment unless I take masses of ventolin. But then ventolin is the order of the day at the moment and they still don't seem to be much better.

my best was 510 but at the moment its about 320.the lowest its ever been is 150 and that was the lowest it will ever go, i hope.

'Whats your peak flow?'

Peak flows are very personalised, they take basic measurements like hight and weight but a lot goes on your technique and control, not everyone is the same and thats why your limits should be set by a qualified practitioner and set just for you. It will also change as you do because it also goes on your best in the last 12mths more than your predicted, so people need to concentarte more on their own than others
