Dr Andrew Harrison an NHS Accident and Emergency doctor, offers advice
on how to prevent an asthma attack and a warning to smokers:

"The most interesting aspect is trying to educate the patients. I am
constantly surprised by how many of them are confused about which of
their 'puffers' they should use at home. Generally, the brown one is to
prevent attacks and must be taken regularly, and the blue one is to
treat attacks when they occur; but few patients seem to adhere to this.

"And then there are those who smoke even though it exacerbates their
asthma and necessitates treatment with steroids - which will ultimately
make their bones brittle"
