My asthmatic friend said I was blowing wrong - you're not supposed to purse your lips like you're blowing out a candle, rather you're supposed 'hoh' at it like you're trying to steam a window

Which meter? The normal issue is this one, which you fellate rather than playing like a trumpet, although I think you'd probably get a lower number by doing it wrong. If you're doing it right, you should be able to do 3 consecutive readings in under a minute and have them all within ±10l.min^-1. The software on the electronic one flags unrepeatable readings.

It's a rectangular one. Maybe Pioneer or Panasonic branded.
I'll try it again and see if I can get repeatable readings without 'trumpeting' it.
Probably should do it in the presence of someone medical but like whatevs bro.

My GP booked me in for this a few years ago so should yours then.

I do remember the no no trumpeting and that no result because either the machine was broken or I was not so good at this.
