2. Criteria
   1. Asymptomatic on most days without interference with normal activity
   2. Occasional exacerbations (Less than twice/week)
      1. Exacerbations are brief (hours to days)
      2. Nighttime exacerbations are 2 or less times monthly
      3. Short-acting Beta Agonist (e.g. Albuterol) use 2 or less times weekly
      4. Oral Corticosteroids required 0-1 times per year
   3. Normal Pulmonary Function Test between exacerbations
      1. FEV1 or PEF >80% predicted
      2. FEV1 to FVC Ratio normal (>85% for age 5-19 years, >80% for age 20-39 years, >75% for age 40-59, then >70%)
      3. PEF Variability <20%
3. Management
   1. See Asthma Stepped Care
   2. No daily medications necessary
   3. Inhaled short acting Beta agonist as needed
   4. If beta agonist use more than twice per week:
      1. Step-up to Mild Persistent Asthma Management
      2. Consider long-term control (Inhaled Corticosteroids)
