Quick Overview

The Mayday Multiperson Trauma Medical Unit is a distributed, five-bag mass casualty response system designed to equip on-site personnel with field-ready supplies to manage life-threatening injuries for up to 1,000 casualties during the critical gap before professional EMS arrival.

The system is organized into five identical 50-pound duffel bags, each containing a proportional share of supplies across six categories: massive hemorrhage control, musculoskeletal injury management, basic wound care, airway and assessment, burn and environmental care, and PPE. This distributed deployment architecture allows multiple teams to stage and operate across large facilities simultaneously, covering different floors, wings, or event zones without depending on a single centralized cache. The design is intended to function as a static asset integrated into an organization's existing Emergency Action Plan.

Hemorrhage control is the system's highest-priority capability and its most significant operational constraint. The entire 1,000-person system contains only one tourniquet, making proficiency with pressure dressings and wound packing the primary operator skill requirement. The system supplies 200 Bloodstopper trauma dressings and 150 multi-trauma dressings to support this approach across a high-casualty environment.

Readiness protocols are as important as deployment protocols. Quarterly inspections must verify bag location, seal integrity, inventory accuracy, and expiration dates. Any bag used in a real incident or training exercise is immediately classified as non-deployable until fully restocked and documented. Operators must familiarize themselves with all components before an incident occurs.

Field Application Steps

1. CONFIRM SCENE SAFETY: Before approaching any casualty, verify there is no ongoing threat such as active fire, structural instability, or an active shooter. Your personal safety is the operational priority. Do not enter an unsafe scene under any circumstances.

2. ACTIVATE THE EMERGENCY ACTION PLAN: Contact internal security and call 9-1-1 immediately. Provide your location, the mechanism of injury, and your best estimate of the number of casualties.

3. DEPLOY ALL FIVE DUFFEL BAGS: Dispatch personnel to each of the five pre-staged bag locations. Each bag weighs approximately 50 pounds. Plan for two-person carries as needed.

4. ESTABLISH A CASUALTY COLLECTION POINT: Move bags to a pre-designated, well-lit, accessible staging area that is upwind and uphill from any hazard. Ensure clear entry and exit points for arriving EMS units.

5. DON NITRILE GLOVES BEFORE ALL PATIENT CONTACT: Put on a fresh pair of nitrile gloves before treating each patient. The system contains 600 pairs. Change gloves between every patient to prevent cross-contamination.

6. CONDUCT INITIAL TRIAGE IF TRAINED: Quickly sort patients by injury severity, prioritizing those with life-threatening hemorrhage. Assign red, yellow, and green categories to guide treatment order and resource allocation.

7. ADDRESS MASSIVE HEMORRHAGE FIRST: Apply firm, direct pressure to severe wounds using Bloodstopper trauma dressings or multi-trauma dressings. If a limb wound is immediately life-threatening and pressure is insufficient, apply the single system tourniquet high and tight on the limb and record the time of application.

8. MANAGE THE AIRWAY FOR UNCONSCIOUS PATIENTS: Perform a head-tilt/chin-lift or jaw-thrust maneuver to open the airway. The Berman Airway Set is available in the kit but must only be used by trained and certified medical professionals.

9. ADDRESS SECONDARY INJURIES: Once immediate life threats are controlled, splint suspected fractures using the six splint kits and ace bandages, dress major wounds with sterile gauze and multi-trauma dressings, and manage burns by cooling first and then applying burn care kit dressings.

10. PREVENT SHOCK IN ALL PATIENTS: Wrap every casualty completely in a solar blanket or paramedic blanket, including the head, regardless of ambient temperature. The system contains 100 solar blankets and 40 paramedic blankets. Shock is a primary killer in trauma environments.

11. REDIRECT MINOR CASUALTIES: Direct walking wounded and volunteers to a separate area to perform basic self-care using the wound care supplies. This conserves trained responders for critical patients requiring direct attention.

12. BRIEF INCOMING EMS AND TRANSFER COMMAND: Have a designated leader prepared to brief the EMS Incident Commander on mechanism of injury, number and location of casualties, triage tag counts, and all treatments already rendered including tourniquet application times. Once EMS assumes command, yield authority immediately and assist only as directed.
