Clinical Presentation & History
A 31-year-old man with status asthmaticus receiving continuous albuterol nebulization develops rising serum lactate and worsening tachycardia in the resuscitation bay, prompting overnight concern for sepsis.

Age: 31 • Gender: Male • Setting: Emergency Triage
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
- Initial Triage and Status Asthmaticus
- Persistent Tachypnea After One Hour of Nebulization
- Lactate Trend and Hemodynamic Trajectory
- Resolution and Disposition
High-Yield Clinical Pearls
Continuous high-dose beta-2 agonist therapy in status asthmaticus commonly produces type B (aerobic) lactic acidosis through Na+/K+ ATPase activation and pyruvate-to-lactate shunting, independent of tissue hypoperfusion.
Rising lactate with normal blood pressure, normal procalcitonin, sinus tachycardia, and tremor in an asthmatic receiving continuous albuterol is drug effect, not sepsis.
Treatment is dose reduction (not cessation) and continued bronchodilator stewardship; antibiotics, sodium bicarbonate, and ICU escalation are not indicated.
Discharge after status asthmaticus requires oral corticosteroid taper, observation for symptom stability, peak flow > 70% predicted, and structured outpatient follow-up.
