Asthma Classifications


Lt Col Reynolds
Asthma is classified by severity and frequency of symptoms. There are two general classifications of asthma: intermittent and persistent. Dr. Green, can you tell us more about classifying asthma?

Dr. Green
Sure thing, Dr. Reynolds. Intermittent asthma is considered the mildest form of asthma. When uncontrolled, this type of asthma causes symptoms up to two days a week, and up to two nights a month. These symptoms include coughing, wheezing, and a feeling of tightness in the chest. Night symptoms may also include night waking.

Persistent asthma means symptoms occur more frequently. Patients with persistent asthma experience the symptoms of coughing, wheezing, or chest tightness at least two to four times a week.

Persistent asthma is further categorized based on the number of times per week and per month that symptoms are experienced.

For example, mild persistent asthma is characterized by symptoms occurring more than two to four times per week, with night symptoms occurring two to four nights per month.

Patients with moderate persistent asthma experience symptoms every day and more than one night a week.

A final subcategory is known as severe persistent asthma. This is the most severe form of asthma, causing symptoms throughout the day on most days and frequently at night.

Asthma classifications help providers determine the right treatment plan for each patient.
