Just wondering if anyone else has ever got different readings?
I meant to say. I keep an eye on peak flow readings and when i am fine i hit around 500 to 550ish at home.
But when i see nurse or doc, i do peak flow and its often lower by about 50.
I never hit same on their meters.
I think it might be cos my meter has plastic mouthpiece to blow through.But when i use nurse or docs meter, it has cardboard one and cardboard one is bigger diameter than mine.
Its only reason i can think for different readings
