Does anyone no what i should be able to blow when im blowing in to a peak flow meter? Im 5ft 7 and im roughly 9 and a half stone.
Im blowing in between 250 and 340.
ive only just been diagnosed with asthma so im still confused about it all.
And also even when im sat down at my computer i feel short of breath. But the blue inhaler doesnt seem to work? Maybe im taking it wrong
