EMS Operations: Lifting, Moving, Ambulance, and MCI

EMS Operations: Lifting, Moving, Ambulance, and MCI

Why This Lesson Matters

Every EMT must move patients safely, maintain a ready ambulance, and function in the chaos of a mass-casualty incident (MCI). A back injury from poor body mechanics can end your career before it starts. A missed deficiency on apparatus check can mean equipment fails when a patient needs it most. Faulty triage at an MCI can cost lives. Master these three skill sets and you are ready for the street.

Part 1: Safe Patient Lifting and Moving

Body Mechanics Principles

Body mechanics means using your body efficiently to avoid injury. Core rules:

• Keep the load close to your body. The farther the weight is from your spine, the greater the force on your lumbar discs.
• Bend at the hips and knees, not the waist. Use your legs — the largest muscles in the body — to generate the lift.
• Keep your back in a neutral (slightly arched) position throughout the lift. Never let your lower back round under load.
• Avoid twisting. Turn your whole body by moving your feet, not by rotating your spine while bearing weight.
• Communicate every move. Call out "Ready, lift" or "Ready, lower" so all crew members act together.

Emergency Drags

Drags are used when a hazard (fire, structural collapse, violence) makes a careful carry impossible.

• Clothes drag: Grasp the patient's collar or shirt behind the head and drag them face-up. Maintain slight head-neck support through the fabric grip. Move in a straight line.
• Blanket drag: Roll the patient onto a blanket, fold the edges to create a handle, and drag toward the patient's head. The blanket distributes force across the body.

Both drags are emergency techniques only — spinal precautions are limited. Remove the patient from danger first, then reassess.

Carries

• One-person carries (walking assist, cradle carry, piggyback): Reserve for conscious, cooperative, lighter patients with no suspected spinal injury.
• Two-person carries: Divide the load — one at the head/torso, one at the legs. The person at the head calls all commands and is responsible for airway access.

Equipment-Assisted Movement

• Stair chair: Fold the patient into a semi-reclined seated position, secure straps across the chest and lap, tilt slightly back, and descend one step at a time with one rescuer at the top handle and one at the bottom handle. Never run on stairs.
• Wheeled stretcher: Lock wheels before loading or unloading. Use the "one-handed tilt" side-rail technique to lower to the ground position. Two providers lift together on command.
• Power cot: The electric lift eliminates most manual lifting force. Learn the controls before patient contact. Still call commands; the cot can shift unexpectedly.

Part 2: Ambulance Pre-Trip Inspection

Federal Motor Carrier Safety Administration regulations and departmental SOPs require a daily vehicle and equipment inspection before the unit goes in service. You are responsible for what you sign off on.

Walk-Around Sequence

1. Chassis and exterior: Tires (tread, pressure), lights (warning, headlights, brake, turn, scene), mirrors, body damage, fluid levels (oil, coolant, brake fluid, windshield washer), fuel level.

2. Cab interior: Seat belts for all positions, radio function, siren/PA, heat/AC, oxygen shutoff valve accessible.

3. Patient compartment: Suction unit (power, canister clean), oxygen (main tank and portable — check pressure gauges), airway kit, BVM, medications carried per local protocol, cardiac monitor/AED, IV supplies, splints, stretcher (latch tested), cot straps, linens.

4. Exterior storage compartments: Extrication gloves, spare PPE, backboards, stair chair, jump bag.

Document every item on the daily apparatus check sheet. If something is missing, damaged, or out of date: remove the unit from service or replace the item before going available, and notify your supervisor. Never falsify a check sheet.

Part 3: START Triage and MCI Operations

What Is START?

START (Simple Triage and Rapid Treatment) is the most widely used field triage system in the United States. It allows a single EMT to triage one patient in approximately 30 seconds using three assessments: respirations, perfusion, and mental status.

The START Algorithm

1. Walk and talk: Direct anyone who can walk to a designated area — tag them Minor (Green).

2. Respirations: Open the airway (head-tilt or jaw-thrust).

• No respirations after airway opening → Expectant (Black).
• Respirations present but greater than 30 per minute → Immediate (Red).
• Respirations 30 or fewer per minute → go to step 3.

3. Perfusion: Check radial pulse or capillary refill.

• Radial pulse absent (or capillary refill greater than 2 seconds) → Immediate (Red).
• Radial pulse present → go to step 4.

4. Mental status: Give a simple command ("Squeeze my hand").

• Cannot follow commands → Immediate (Red).
• Follows commands → Delayed (Yellow).

Triage Tag Colors

| Color | Priority | Meaning |

|---|---|---|

| Red | Immediate | Life threat, survivable with prompt intervention |

| Yellow | Delayed | Serious but can wait |

| Green | Minor | Walking wounded |

| Black | Expectant | Dead or unsurvivable injury |

EMT Role at an MCI

• Announce the incident to dispatch and establish or confirm incident command.
• Do not self-deploy — report to staging or the triage sector as assigned.
• Document patient count, tags assigned, and your sector to report to incident command.
• Limit treatment during primary triage to opening airways — do not stop to treat one patient when others are untagged.
• Follow ICS-100 structure: report to your supervisor, use clear-text radio communication, and request additional resources through the chain of command.

Safety Reminders

• Wear nitrile gloves for all patient contact; add eye protection when fluids are possible.
• Never lift alone if the load exceeds safe solo limits — request help.
• At an MCI, treat scene safety as dynamic: hazards can expand. Do not enter until the scene is controlled.
