THE MARCH FRAMEWORK

In a medical emergency, confusion costs time.
Time costs lives.

The MARCH framework is a structured approach to trauma care that focuses on treating the most preventable causes of death first.

It stands for:

Massive Hemorrhage
Airway
Respiration
Circulation
Hypothermia / Head Injury

Originally developed through battlefield trauma research and refined through modern tactical and civilian emergency care doctrine, MARCH provides a clear order of operations when seconds matter.

The principle is simple:

Treat what will kill the patient first.

Under stress, human performance changes.

Fine motor skills decline.
Decision-making narrows.
Attention locks onto what is obvious rather than what is critical.

Without structure, responders may treat the wrong problem first.

The MARCH framework prevents that.

It provides a shared mental model that works across environments:

• Law enforcement
• Fire and EMS
• Military
• Schools
• Workplaces
• Large public events
• Civilian response settings

Structure creates clarity.

Clarity improves survivability.

Before medical care begins, your safety is paramount.
If a threat is present, it must be mitigated or you must move to a position of safety before initiating care.
If the scene becomes unsafe at any time, your priority must shift back to your own safety. Withdraw, create distance, and reassess before continuing care.
Never enter a scene that is clearly unsafe.
You cannot provide effective treatment if you become a casualty

Severe bleeding can cause death in minutes.

Before airway.
Before breathing.
Before anything else.

Interventions may include:

• Commercial tourniquet applications
• Wound packing with hemostatic agents
• Pressure dressings
• Junctional hemorrhage control

Rapid hemorrhage control remains one of the most effective life-saving actions in trauma care.

Once bleeding is controlled, the next priority is confirming airway patency.

An obstructed airway prevents oxygen from reaching the brain. Without oxygen, permanent injury begins quickly.

Airway management may involve:

• Positioning and manual maneuvers
• Clearing obstructions
• Airway adjuncts within scope of practice
• Advanced airway management when appropriate

Scope of practice and environment determine intervention but assessment always comes early.

Confirm effective breathing

Chest trauma can compromise ventilation even when the airway is open.

This phase focuses on identifying and managing:

• Penetrating chest wounds
• Tension pneumothorax
• Respiratory distress
• Blast or blunt chest injuries

Recognition and timely intervention are critical to preventing rapid deterioration.

Support perfusion and identify shock early

After bleeding, airway, and breathing are addressed, circulation must be evaluated.

Circulation is about whether oxygenated blood is reaching vital organs.

Shock can be present before blood pressure drops. Waiting for hypotension means waiting too long.

Key Early Indicators

Two of the most reliable early signs of shock are mental status and pulse.

1. Mental Status: Changes in alertness often occur early. Watch for confusion, restlessness, agitation, lethargy, or decreased responsiveness. If the brain is not receiving adequate blood flow, mental status will change.
2. Pulse:Assess rate and quality.A rapid, weak, or thready pulse may indicate compensating blood loss or poor perfusion.

• Additional SignsPale, cool, or clammy skin
• Rapid breathing
• Delayed capillary refill
• Suspected internal bleeding

Shock is a clinical diagnosis. It is not defined by blood pressure alone.

Early recognition improves survivability

Preserve body temperature.

Trauma patients lose body heat quickly, even when the weather is warm.

When someone becomes too cold after an injury, their body cannot clot blood as well and bleeding can worsen. Being cold also makes it harder for the heart and organs to function properly.

• This phase includes: Keeping the patient warm with blankets or insulation
• Shielding them from wind, rain, or cold surfaces
• Monitoring alertness and responsiveness
• Continuing reassessment

Loss of body heat is one of the most overlooked parts of trauma care. When it is not addressed early, it can make shock worse and increase the risk of death hours or even days later.

Keeping an injured person warm is not a comfort measure. It is a critical part of survival.

MARCH is not just a checklist.

It is a systems design model.

• It scales from: Individual IFAKs
• Patrol vehicle kits
• Fire apparatus trauma bags
• School emergency cabinets
• Workplace response programs
• Mass gathering and crowd medicine planning

When training, equipment, and policy are aligned around the same framework, response becomes faster, clearer, and more consistent.
