Er Acute Breathlessness Pathway

ED acute breathlessness clinical pathway

Clinical decision support pathway for a person presenting to the emergency department with acute breathlessness / dyspnea. This is a clinical-protocol PlanDefinition: danger-sign gate → airway rescue → parallel stabilization → classify etiology → branch-specific management.

See also: CDS clinical reasoning, ER chest pain pathway.


Clinical overview

The pathway follows standard ED breathlessness logic:

  1. Confirm context — active emergency encounter with dyspnea as chief complaint.
  2. Review danger signs — select any that apply (altered consciousness, exhausting breathing, silent chest, refractory hypoxemia, hemodynamic instability, unprotected airway), or None of the above.
  3. Airway rescue (when any danger sign is selected — not when None of the above) — senior/ICU help, NIV preparation, intubation readiness.
  4. Parallel stabilization — Tasks: IV access, start oxygen. Orders: CXR, ECG, BMP, lactate, troponin, BNP.
  5. Classify etiology — SNOMED CT working diagnosis (typeahead + curated quick-picks). CQL maps concepts to mutually exclusive branches:
    • Cardiogenic pulmonary edema / acute HF
    • COPD / asthma exacerbation
    • Pulmonary embolism
    • Pneumonia / infection
    • Pneumothorax
    • Upper airway obstruction
    • Other / unclear (explicit Unknown, or any non-curated concept)
  6. Branch management (exactly one order set after classification):
    • Cardiogenic / acute HF — NIV prep, IV furosemide, BNP, echo, daily weight, cardiology
    • COPD / asthma — salbutamol neb, prednisolone, peak flow, pulmonology
    • PE — D-dimer, CT chest, therapeutic enoxaparin, general medicine
    • Pneumonia — CBC, blood cultures, ceftriaxone + azithromycin, general medicine
    • Pneumothorax — CXR, chest-drain prep, senior/ICU
    • Upper airway — senior/ICU, ENT, RSI prep
    • Other / unclear — clinical reassessment, CBC, general medicine
