WHAT IS THE TREATMENT AND CAUSES OF ASTHMA?

Depend upon severity of condition
Short acting and long acting beta agonists
At start if condition is not sever
Inhaler steroid if sever condition

Asthma is allergic condition

My second choice for the case is Ventolin spray

Depends on the case

In community treatment we used injectable like hydrocortisone and aminoplin
