Initial Impression: Severe Allergic Reaction (Anaphylaxis) Justification for F2 Classification: - Rapid onset of severe symptoms including airway compromise (throat tightness, difficulty breathing, wheezing). - Known allergy to shellfish and history of previous reactions. - Potential for rapid deterioration without prompt intervention. - Patient has used her EpiPen but is still symptomatic Differential Diagnoses: 1. Anaphylaxis (high probability) 2. Angioedema (less likely, but possible) 3. Acute Asthma Exacerbation (less likely given the rapid onset of symptoms and known allergy) 4. Foreign Body Airway Obstruction (unlikely based on history) Required Actions: - Dispatch of ground EMS with ALS capabilities. - Initiate oxygen therapy if available. - Monitor patient's airway, breathing, and circulation closely. - Prepare for potential advanced airway management. - Rapid transport to nearest hospital with emergency services.
