CERT U4 MED OP STUDY GUIDE
CERT Disaster Medical Operations Unit 4: Mass Casualty Incidents (MCI)
MCI Response Overview
Professional Responders’ Responsibilities:
• Establish command and control of the incident area.
• Conduct a scene size-up and setup.
• Direct survivors to treatment areas.
• Identify and treat survivors with life-threatening injuries immediately.
• Identify deceased victims and those too severely injured to save.
• Manage medical transportation.
• Secure the area to protect responders, survivors, and evidence.
• Remove debris and other safety or health threats.
CERT Volunteers’ Responsibilities:
• Put on Personal Protective Equipment (PPE).
• Locate the nearest professional responder and introduce yourself.
• Communicate your CERT affiliation and ask how you can help.
• If told to leave, report to your CERT Team Leader.
• If no professionals are available, assess the situation and provide life-saving interventions as necessary, reporting your actions to professionals upon their arrival.
Medical Treatment Areas
Types of Medical Treatment Areas:
1. Decentralized:
• Set up near damaged sites when many injured survivors are spread across several locations.
• Allows for immediate treatment close to where injuries occur.
• Influenced by severity of damage, number of injuries, safety, accessibility, and potential for expansion.
2. Centralized:
• Established when there are few injured survivors at multiple sites, allowing for logical consolidation.
• Includes treatment areas and a morgue for effective use of resources.
Determining Factors:
• Severity of damage.
• Number of injuries.
• Safety of the environment.
• Accessibility for transportation vehicles.
• Expandability of the treatment area.
Light Search and Rescue
Assessment of Buildings:
• Categorize damage as Light, Moderate, or Heavy.
Head to Toe Assessment (DCAPBTLS):
• DCAPBTLS:
• Deformities
• Contusions
• Abrations
• Punctures/Penetrations
• Burns
• Tenderness
• Lacerations
• Swelling
Order of Assessment:
• Head, Neck, Shoulders, Chest, Arms, Abdomen, Pelvis, Legs.
Assessment Considerations:
• Verbalize your actions.
• Assess all survivors.
• Look, listen, and feel.
• Ask for permission before touching.
Signs of Closed Head Injury
Indicators:
• Change in consciousness.
• Inability to move one or more body parts.
• Severe pain or pressure in the head, neck, or back.
• Tingling or numbness in extremities.
• Difficulty breathing or seeing.
• Heavy bleeding, bruising, or deformity of the head and spine.
• Blood or fluid in the nose or ears.
• Bruising behind the ears or around the eyes (raccoon eyes).
• Uneven pupils.
• Seizures.
• Nausea or vomiting.
Maintaining Hygiene
Key Practices:
• Wear gloves, N95 masks, and goggles.
• Wash hands and use sanitizer frequently.
• Keep dressings sterile.
• Wash areas that come into contact with body fluids.
• Control disposal of bacterial sources:
• Place waste in plastic bags, tie them off, and mark as medical waste.
• Bury human waste.
• Avoid touching anything warm, wet, and not yours.
Purifying Water
Methods:
• Boil water for 1 minute.
• Use bleach: 8 drops per gallon (16 if dirty); let stand for 30 minutes.
• Use water purification tablets.
Knowledge Checks
Water Sanitation:
• Boil water for 1 minute.
• Use purification tablets.
• Use non-perfumed bleach for treatment.
Test Questions
1. MCI Response: Conduct a size-up and provide life-saving interventions if safe. Identify yourself to a professional responder and communicate relevant information.
2. Sanitization Maintenance: Dispose of waste in plastic bags, tie them off, mark them as “medical waste,” and control bacterial source disposal.
3. Signs of Closed Head Injury: Change in consciousness, raccoon eyes, inability to move body parts.
4. First Step in Size-Up: Gather information.
5. True Statement: Establish a medical treatment area by selecting a site and treatment area as soon as survivors are confirmed.
6. Hygiene Maintenance: Wash hands and wear gloves.
7. Considerations for Treatment Area: Ensure it is free of hazards, resources are effectively used, transportation is accessible, and it is expandable.
8. Wait Time for Bleach Purification: 30 minutes before using water purified with bleach.
9. Injury Management: For closed head/neck/spinal injuries, minimize movement; move only if in danger.
10. True Statement: For MCI, provide life-saving interventions only if professional responders are not available.
