I have a very mild form of asthma, diagnosed winter 2007. The doctor prescribed the classic blue salbutamol reliever, boy what a relief.
I've only needed to use it sporadically. When I get a bit of trouble, it is excaberated hugely by synthetic scents like those found in air freshener or cigarette smoke.
Just been back to the docs for a new inhaler prescrip. She asked if I had a flow meter at home (I don't), and when I looked in to it I found numerous placing saying once-off measurements are meaningless. Each person needs to keep an ongoing list of measurements so that they know what is normal for them (for the record, I managed 463 this time - the charts say that 580 would be normal for my age and height).
Do you think it is worthwhile having a meter and keeping records?
