Initial Impression: Cardiac Arrest Justification for F1 Classification: - Unresponsive, not breathing, no pulse are clear indicators of cardiac arrest. - Life-threatening condition requiring immediate intervention. - Time-critical condition where every second counts for patient survival. Differential Diagnoses: 1. Cardiac Arrest due to underlying heart condition (high probability) 2. Respiratory Arrest leading to Cardiac Arrest (less likely given no history of respiratory issues) 3. Hypoglycemia leading to unresponsiveness (less likely given patient's diabetes control) 4. Stroke (less likely given no focal neurological signs reported) Required Actions: - Immediate dispatch of ground EMS with ALS capabilities. - Dispatch of first responders with AED. - Pre-arrival instructions for CPR to caller. - Early hospital notification for preparation for cardiac arrest protocol.
