Initial Impression: Acute Respiratory Failure secondary to COPD Exacerbation with possible Acute Heart Failure Justification for F1 Classification: - Life-threatening condition requiring immediate intervention - Severe dyspnea, cyanosis, and altered mental status indicate critical respiratory compromise - High risk of respiratory arrest and cardiac arrest if untreated Differential Diagnoses: 1. Acute COPD Exacerbation (most likely) 2. Acute Heart Failure with Pulmonary Edema (high probability given past history) 3. Pulmonary Embolism (less likely but must be considered) 4. Pneumothorax (less likely given presentation) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities - Rapid transport to nearest hospital with respiratory support - Oxygen therapy and assisted ventilation if required - Notification of hospital emergency department for immediate patient arrival
