Peake flow personal best

[elmothebrave]

Hey guys,

Just wanted to know how often people adjust their personal best peak flow? Mine is currently set at 500 but I've been done at 85% of that for at least a month now. Just want to get an idea of everybody else's timings.

I will be interested to see the response as I have been wondering exactly the same thing!

It varies depending how old you are. There’s a chart here so you can see what the average for your age is:blf.org.uk/support-for-you/...

Mine is well above the estimated so I never use that. Brass instruments and athletics seem to increase lung capacity well. I record my own pb and work off that.

I would have thought if your asthma is well controlled there would be a gentle decline with age assuming you remain reasonably fit, my peak flow has dropped because my fitness has dropped rather than because my asthma is out of control
