Peak flow readings back to back

[GreatGateway]

If you take a peak flow recording, and then 5 seconds or so later take another, would you expect a higher or lower result? I've gotten different answers from everyone I ask but I've seen mine change from 660 to 690 to 710 with 3 readings in quick succession.

Hi

The first will be the most difficult, as you get into rhythm I would expect some improvement.

Which seems to make sense by you continued increase.

[GreatGateway in reply to stone-UK]

Thank you; does that mean the first reading is the true value or is the highest I can manage after a few puffs the true peak flow?

Hi

On my spirometer, they use the best from three.

flippin' 'eck - I average about 130 - and can sometimes up it to 150 on the second blow by dint of squeezing out every last squirt of air before I breathe in again. When I get infections I sometimes drop to 110 - even 100 - and I really start to struggle to even move about. Last summer when I was feeling really well I managed 170 for a few weeks and felt on top of the world. So your readings are fantastically good. You lucky thing. I don't use my meter every day just when I notice a bit of a change - for the better or worse.

It does seem high but I do feel very symptomatic, plus for my height and age it's pretty average I think that's why I'm worried about readings in the 600s; about 100 l/min difference from my best sounds significant to me xD

Opposite for me, first is usually the best.

[Hidden in reply to O2Trees]

Trust you to be contrary O2 xx

[Ergendl in reply to O2Trees]

Me too.

My 3rd reading of my best of 3 is usually my highest one. It makes the average around 350 which I am happy with. x

My PEF and FEV1 are generally best on the first blow and decrease for every subsequent blow. It is the same when I go for a PFT or spirometry.

I wouldn't worry tooooooo much if I was getting those readings ,on a good day I can manage 350 max ,usually I'm about 300',

[MoyB]

If I can get to 200 I'm thrilled!

I've always been told to take the best of 3 as the reading.

I've always been told the best of 3.

That's very good readings, so good in fact I reckon you must be free of illness

[GreatGateway in reply to twopars12]

Unfortunately I don't feel that way; my peak flows are large because of my height and age, and they drop a huge amount if I get symptomatic. Only Ventolin helps. So as much as I don't want asthma it appears inevitable ;(

Working in the same way Huffing Techneque does?

I can get 150. That doesn't sound too good. After all the stress the DWP have caused me that doesn't surprise me at all. Thank you DWP & ATOS!
