My humble answer: Actually, I'm going to quote a doctor for the answer to this question. Dr. James Thompson M.D. in his post, "Combination Inhalers for Asthma Control: The New Kid on the Block," provides the following definition tio persistent asthma:
When is asthma persistent? Great Question!
Asthma is persistent when any one of the following is true:
- There are limitations in normal routine (work/school) because of asthma. For example, huffing and puffing as you walk up one flight of stairs, noticing classmates or coworkers gliding by with ease.
- Symptoms of asthma (cough, wheezing, shortness of breath, or chest tightness) occur more than two days per week.
- Reliever inhaler is required more than two days per week (don't count the inhalations taken to prevent exercise-induced asthma).
- Night time awakenings from asthma symptoms occurs more than two nights per month.
- Lung function is less than 80 percent predicted by lung function test (Spirometry or Peak Flow Rate).
- There has been more than one severe asthma attack in the last 12 months.
- Bronchodilator inhaler (Every asthmatic should have one on hand at all time)
- Singulair (if this alone does not control your asthma, move on to #3 below)
- Inhaled corticosteroid (if this does not control your asthma, move on to step #4 below)
- Combination inhaler (if this doesn't control your asthma, seek an asthma specialist)
