The author appears to have grabbed a bunch of pamphlets on his way out of the doctor's office and edited them down to the minimum needed to address the subject, if he were addressing 10 year olds, that is.  More information is available, for free, on any internet search, on Wikipedia, on my pulmonologist's website. Please spare yourself this useless read.
