What exactly is asthma? Asthma is a reversible obstruction to breathing. The air passages become constricted, inflamed and swollen resulting in decreased air flow.
A person may experience wheezing, coughing, or simply notice that they are short of breath. Asthma may be life long or transitory, some “out grow it or grow into it.”
What triggers asthma? Allergens such as dust mites or animal dander, aerosolized materials such as smoke or perfume, respiratory infections and even exercise can all trigger an asthmatic episode.
How is asthma treated? One first stratifies according to frequency and severity of attacks. Mild intermittent is the least frequent and severe, and severe persistent the most. The former is treated with only rescue medicine like albuterol, however, controller meds such as inhaled steroids should be used for anything more frequent.
The use of inhaled cortico- steroids (ICS) has a small amount of risk, but the benefits far outweigh such risks. The ICS not only prevents death by suffocation, but probably also modifies the progression of the disease process.
Who has asthma? Between 10 and 20 percent of Americans have asthma at some time in their life. In Santa Clarita we are on the high end of that range. This is probably due to high ozone concentrations in our area. Ozone not only triggers asthma, it causes long term harm to developing lungs, especially when youngsters exercise day after day in unhealthful air. What can be done to decrease the damages? Become an activist, make these websites your favorites and when there are bad days call other parents, teachers and coaches to get the sports moved to the morning, or move all summer sports to the morning. It’s really during July thru September between 3 p.m. and 6 p.m. that outdoor sports need to be limited. It’s for our kids’ lungs.
How do we find out about bad air days? Two sites, one by the SCAQMD: www.aqmd.gov/telemweb/Forecast.aspx will give a good forecast.
But the EPA website, www.airnow.gov, is well worth the difficulty, because it will guide one through our Federal Government’s recommendations regarding ozone levels for any day, in real time. For instance it recommended on July 4, 2007 limiting out door sports between 3 and 5 p.m.
