Urgent Care · Common Complaints
Asthma / COPD Flare
Asthma and COPD exacerbations seen in urgent care need a structured severity assessment that drives disposition. Bronchodilators, systemic steroids, and reassessment after treatment determine who goes home and who goes to the ED. This page covers the can't-miss mimics (impending respiratory failure, pneumothorax, PE, pneumonia/sepsis, anaphylaxis, cardiac asthma from CHF), red flags (SpO₂ < 92%, single-word speech, accessory muscle use, silent chest, peak flow < 50% predicted), the minimum safe first-pass workup, in-office treatment protocol with reassessment after each round, outpatient management criteria, escalation criteria, documentation patterns, and detailed return precautions for patients sent home with a steroid taper. Written for NPs, PAs, and MDs in outpatient practice.

Urgent Care · Common Complaints
Asthma / COPD Flare
Why this symptom matters
Severity assessment drives disposition. Bronchodilators, steroids, and reassessment after treatment — then decide who goes home and who goes to the ED.
What must I not miss first?
- Impending respiratory failure
- Pneumothorax
- PE
- Pneumonia / sepsis
- Anaphylaxis
- Cardiac asthma (CHF)
Red flags — escalate or work up urgently
- SpO₂ < 92% on room air (or below baseline in COPD)
- Single-word speech, accessory muscle use, paradoxical breathing
- Silent chest, drowsiness, exhaustion
- RR > 30 or < 8
- Peak flow < 50% predicted (or personal best) — or unable to perform
- Failure to improve after 1 hour of in-clinic treatment
- Prior intubation, ICU admission, or multiple recent ED visits
Immediate Management — While You Work It Up
- Albuterol 2.5 mg nebulizer — start immediately. May repeat × 3.
- Ipratropium 0.5 mg nebulizer — add to albuterol for moderate to severe flare.
- Prednisone 40–60 mg PO — start in clinic and prescribe a 5-day course.
- Oxygen — titrate to SpO₂ > 92%. > 88% in COPD to avoid hypoxic drive suppression.
- Magnesium sulfate 2 g IV — for severe refractory bronchospasm before transfer.
- Peak flow before and after treatment — document response to treatment.
- If no improvement after 3 nebulizer treatments — call 911 for transport.
Minimum safe first-pass workup
- What to ask: baseline severity, recent steroid use, prior intubations/ICU, current medications and adherence, triggers, smoking, fever
- What to examine: vitals + SpO₂ + work of breathing, mental status, lung exam (wheezing, prolonged expiration, silent chest)
- Peak flow before and after treatment if asthma
- Albuterol ± ipratropium nebs back-to-back (or MDI with spacer)
- Oral steroids early (prednisone 40–60 mg)
- CXR if focal findings, fever, or first presentation; consider PE if pleuritic/asymmetric
What can usually be managed outpatient
- Mild–moderate flare with good response to nebs, post-treatment SpO₂ ≥ 95% RA, peak flow > 70% predicted
- 5-day prednisone burst (40–60 mg) for asthma; 5 days prednisone 40 mg for COPD flare
- Antibiotics for COPD flare if increased sputum purulence + volume + dyspnea (Anthonisen criteria)
- Spacer technique check, asthma action plan, follow-up in 1–3 days
When to escalate to ED / higher level of care
- Any red flag above
- Failure to improve after 60 minutes of aggressive treatment
- Hypoxia not correcting, AMS, exhaustion, silent chest
- Suspected pneumothorax, PE, anaphylaxis, or pneumonia with sepsis
- Patient with prior intubation and current significant flare
What to document when the diagnosis is still uncertain
- Pre- and post-treatment vitals, SpO₂, peak flow
- Treatments given (number of nebs, steroid timing, antibiotic if used)
- "Pneumothorax / PE / pneumonia / anaphylaxis / cardiac asthma considered because…"
- Inhaler technique reviewed; written action plan provided
- Return precautions and follow-up timing
Safety-net & return precautions to give
- Return or call 911 for trouble breathing, blue lips, can't speak full sentences, rescue inhaler not helping, chest pain, or confusion.
- Use rescue inhaler every 4 hours as needed; if needed more often, return today.
- Finish steroid course. Follow up in 1–3 days.
