Initial Impression: Anaphylactic Reaction to Shellfish Justification for F2 Classification: - High probability of severe allergic reaction based on known history and symptom onset - Patient experiencing respiratory distress and throat tightness - Time-sensitive condition requiring rapid intervention to prevent airway compromise and cardiovascular collapse Differential Diagnoses: 1. Anaphylaxis (high probability) 2. Severe Angioedema (less likely without known triggers other than allergy) 3. Acute Asthma Exacerbation (less likely given patient's history and rapid onset) 4. Panic Attack (less likely given physical symptoms) Required Actions: - Dispatch of ground EMS with ALS capabilities - Immediate administration of epinephrine (if EpiPen fails or if available) - Airway management protocols initiation - Preparation for transport to nearest hospital with emergency services
