How to Write an Albuterol Nebulizer Order

For adults, order albuterol nebulizer solution 2.5-5 mg every 20 minutes for 3 doses, then 2.5-10 mg every 1-4 hours as needed; for children, order 0.15 mg/kg (minimum 2.5 mg) every 20 minutes for 3 doses, then 0.15-0.3 mg/kg every 1-4 hours as needed. 1

Standard Order Components

Adult Dosing

  • Initial treatment: Albuterol 2.5-5 mg via nebulizer every 20 minutes for 3 doses 1
  • Maintenance: 2.5-10 mg every 1-4 hours as needed based on clinical response 1
  • Severe exacerbations: Consider continuous nebulization at 10-15 mg/hour 2

Pediatric Dosing

  • Weight-based: 0.15 mg/kg (minimum dose 2.5 mg) every 20 minutes for 3 doses 1, 3
  • Maintenance: 0.15-0.3 mg/kg every 1-4 hours as needed 1, 3
  • Severe cases: Continuous nebulization at 0.5 mg/kg/hour 3, 4
  • Children <15 kg: Use 0.5% solution instead of 0.083% for doses less than 2.5 mg 5

Administration Specifications

Solution Preparation

  • Dilution: Dilute to a minimum of 3 mL total volume with normal saline for optimal nebulization 1, 2, 3
  • Standard concentration: 0.083% solution (2.5 mg/3 mL) requires no dilution 5
  • Gas flow rate: 6-8 L/min 1, 2
  • Driving gas: Use oxygen when available, especially in hypoxic patients 3, 4

Treatment Duration

  • Each nebulization treatment should last approximately 5-15 minutes 5
  • Continue until no more mist is formed in the nebulizer chamber 5

Severity-Based Ordering Algorithm

Mild-to-Moderate Exacerbations

  • Start with 2.5 mg every 20 minutes for 3 doses 1, 2
  • Reassess after initial 3 doses 1
  • If improving, transition to every 1-4 hours as needed 1
  • Alternative: MDI with spacer (4-8 puffs every 20 minutes) is equally effective with proper technique 1, 2

Severe Exacerbations (FEV1 <40% predicted)

  • Use higher doses: 5 mg every 20 minutes for adults 1
  • Add ipratropium: 0.5 mg for adults, 0.25-0.5 mg for children to first 3 doses 1, 2
  • Consider continuous nebulization if inadequate response after 1 hour 2, 6
  • Continuous dosing provides greater FEV1 improvement than intermittent dosing in severe obstruction 6

Sample Order Format

"Albuterol 2.5 mg via nebulizer with 3 mL normal saline at 6-8 L/min oxygen flow, administer every 20 minutes × 3 doses, then every 1-4 hours as needed for wheezing/dyspnea"

For severe cases: "Albuterol 5 mg + ipratropium 0.5 mg via nebulizer with normal saline at 6-8 L/min oxygen flow, administer every 20 minutes × 3 doses, then albuterol alone every 1 hour as needed"

Critical Monitoring Parameters

During Treatment

  • Monitor heart rate, respiratory rate, and oxygen saturation before and after each treatment 1
  • Watch for tachycardia, tremor, and hypokalemia, especially with frequent or high-dose administration 2, 3, 4
  • Reassess clinical response after each dose cycle 1, 2

Response Assessment

  • Measure FEV1 or peak flow if possible 1
  • Response to initial treatment is a better predictor of hospitalization need than initial severity 2, 4
  • Most patients (72%) with severe asthma require cumulative doses of 7.5 mg to achieve maximal bronchodilation 7

Common Pitfalls to Avoid

  • Underdosing severe exacerbations: Standard 2.5 mg doses may be insufficient; 50% of hospitalized asthmatics require higher doses 7
  • Omitting dilution: Always dilute to at least 3 mL for proper nebulization 1, 3
  • Wrong gas flow rate: Flow rates below 6 L/min result in suboptimal delivery 1, 2
  • Forgetting ipratropium: Should be added to first 3 doses in moderate-to-severe cases 1, 2
  • Continuing ipratropium after hospitalization: No additional benefit once admitted 1

Alternative: Levalbuterol

  • Dosing: Half the milligram dose of albuterol (1.25-2.5 mg for adults, 0.075 mg/kg for children) 1, 2
  • Provides comparable efficacy with potentially fewer side effects 2, 3
  • Order as: "Levalbuterol 1.25 mg via nebulizer every 20 minutes × 3 doses, then every 1-4 hours as needed"
