1. Patient has a documented diagnosis of asthma.

2. Asthma severity is classified as mild intermittent.

3. Patient is currently experiencing status asthmaticus, defined as a severe, acute asthma exacerbation that does not respond to initial standard therapy.

5. Clinical evaluation confirms ongoing respiratory distress and/or decreased peak expiratory flow despite treatment.

6. No evidence of alternative diagnoses explaining the acute symptoms.
