How does the MARCH priority sequence guide field care?

• A. Massive hemorrhage first, then airway, respiration, circulation, and then addressing impairment and hypothermia
• B. Airway first, then hemorrhage, then respiration
• C. Circulation first, then hemorrhage, then airway
• D. Impairment and hypothermia before hemorrhage

Answer: (A)

Massive hemorrhage is addressed first because uncontrolled bleeding is the most immediate and potentially fatal threat in trauma. Stopping the bleed quickly with measures like tourniquets, hemostatic dressings, and direct pressure buys crucial time and reduces preventable deaths. Once the bleeding is controlled, the next priority is to secure the airway to ensure the patient can breathe and receive adequate oxygen. After the airway is protected, assess and support breathing to maintain oxygenation and ventilation. Only then focus on circulation, which involves evaluating for shock, continuing hemorrhage control, establishing IV/IO access, and fluid resuscitation as appropriate. Finally, address impairment and hypothermia. Neurological status and preventing cold-induced complications are important, but they are prioritized after life-threatening bleeding, airway, and breathing threats have been managed. So the sequence—massive hemorrhage first, followed by airway, then respiration, then circulation, and finally impairment and hypothermia—reflects the order of life-saving priorities in field care.
