As someone newly diagnosed with Asthma I am still unsure about many things.
During this last bad chest infection I have had great difficulty trying to get a peak flow reading, each time I try to blow into the tube the coughing starts and mucus blocks my throat.
Is this usual and if so how do you get an accurate reading on these occasions.
My normal PF best is 360, while really poorly I was unable to get past 150.
