11.2 Tactical Patient Assessment and Bleeding Control
Key Takeaways
- BPOC Chapter 40 teaches three phases of law enforcement medical assistance: direct threat, indirect threat, and evacuation care.
- MARCH and XABCDE are patient-assessment frameworks that put catastrophic bleeding before airway and breathing checks.
- Tourniquets, wound packing, direct pressure, and pressure dressings are selected by bleeding type and officer training.
- Exam scenarios often reward reassessment and communication after the first intervention.
Threat-Zone Phases and Hemorrhage Control
BPOC 40.4 divides law enforcement emergency medical assistance into direct threat care, indirect threat care, and evacuation care. Direct threat care is the hot-zone or care-under-fire phase, where the focus is mitigating the threat, moving, communicating, getting off the X, preventing more casualties, and staying in the fight. Indirect threat care occurs in relative safety and shifts attention to security, an immediate action plan, and medical care.
Evacuation care occurs while moving the casualty toward EMS or a hospital. The BPOC focus is reassessing prior interventions and performing additional interventions as trained. This matters on the exam because many wrong answers treat the phases as places on a map only. The better answer asks whether the threat has changed and whether security supports more care.
| Phase | BPOC phrase | Testable priority |
|---|---|---|
| Direct threat | Hot zone or care under fire | Move, mitigate, communicate, prevent more casualties |
| Indirect threat | Warm zone or tactical field care | Security, immediate plan, lifesaving care |
| Evacuation | Cold zone or CASEVAC | Reassess and continue care while moving to EMS |
BPOC 40.5 teaches MARCH and XABCDE as patient assessment patterns. MARCH means massive hemorrhage, airway, respirations, circulation, and head or temperature concerns. XABCDE uses exsanguination, airway, breathing, circulation, disability, and environment. Both push catastrophic bleeding to the front because uncontrolled extremity or junctional bleeding can kill rapidly.
BPOC 40.6 then links bleeding type to intervention. Direct pressure is applied directly to the wound. A tourniquet is for massive extremity hemorrhage and is placed high and tight or at least three inches above the wound, with time noted. Wound packing is for massive junctional hemorrhage, and a pressure dressing can manage less severe bleeding or maintain pressure after packing.
Applied Scenario Guidance
If a question says the shooter is still active, the best answer is not a full patient survey in the open. Think direct threat care: move to cover or out of the danger area if possible, communicate, and prevent additional casualties. Once the stem says the area is secured or relatively safe, switch to indirect threat care and apply MARCH or XABCDE.
For a leg wound with heavy bright bleeding, choose a tourniquet before a full head-to-toe assessment. For groin, armpit, shoulder, or collarbone junctional bleeding, choose wound packing and direct pressure when trained and equipped. After any bleeding intervention, reassess. A second tourniquet above the first may be needed if bleeding is not controlled.
Exam Trap
Do not let airway-first habits override the BPOC tactical sequence. In ordinary CPR training, airway and breathing may receive early attention, but BPOC tactical assessment puts massive hemorrhage or exsanguination first. Another trap is writing the tourniquet time only after transport. The objective says note the time of application, and reassessment belongs in evacuation care.
