Initial Impression: Cardiac Arrest Justification for F1 Classification: - Patient is unresponsive, not breathing, and pulseless. - Life-threatening emergency requiring immediate intervention. - Time-critical condition, rapid deterioration expected without intervention. Differential Diagnoses: 1. Cardiac Arrest due to myocardial infarction (high probability) 2. Sudden cardiac arrest due to arrhythmia (high probability) 3. Pulmonary embolism (less likely given lack of prior symptoms) 4. Severe Hypoglycemia (less likely given diabetic history and lack of known recent insulin dose) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities. - Dispatch of fire service as first responders. - Initiate CPR instructions to caller. - Early notification of hospital emergency department for anticipated arrival.
