Initial Impression: Respiratory Failure secondary to COPD exacerbation, with potential cardiac involvement. Justification for F1 Classification: - Unresponsive patient with agonal breathing and cyanosis indicates immediate life-threatening condition - High probability of respiratory arrest - Time-critical intervention required to maintain airway and oxygenation Differential Diagnoses: 1. Acute COPD exacerbation with respiratory failure (most likely) 2. Acute Myocardial Infarction (possible given history of CHF) 3. Pulmonary Embolism (less likely, but possible) 4. Severe Hypoglycemia (less likely, but should be ruled out) Required Actions: - Immediate dispatch of ALS ambulance - Pre-arrival instructions for CPR to caller - Early notification of hospital for potential intubation and critical care needs
