Every EMS call generally involves multiple patient transfers:
From initial position → backboard or stretcher → ambulance → emergency department (ED) bed.
Goals of proper movement:
Protect patient from further harm.
Prevent EMT/team musculoskeletal injury.
Maintain efficiency of patient care.
Core competencies to master:
Lifts, carries, body drags (emergency, urgent, non-urgent).
Spinal-injured patient packaging vs. non-spinal.
Use of equipment: wheeled stretcher, stair chair, scoop/folding/basket/flexible stretchers, backboards, bariatric aids, restraint devices.
Verbal commands & team positioning.
Primary transport device in modern ambulances.
Construction & weight:
Tubular metal main frame; weighs 40–145\,\text{lb} (18–66\,\text{kg}).
Three-section inner frame with platform plates.
Hinged head section for semi-Fowler or full-upright positioning; foot section may hinge to elevate knees (not on all models).
Guardrails:
Retractable; must be locked up after loading.
Undercarriage:
Folding; adjustable height 12–36\,\text{in} (30–91\,\text{cm}).
Safety interlock: stretcher must be slightly lifted to fold, preventing sudden drops if handle is pulled accidentally.
Mattress requirements: fluid-resistant, non-absorbent.
Strap use mandatory for all transports to prevent crash ejection.
Words of Wisdom: Only transport patient on alternate device (folding stretcher/backboard on bench) when two pts share one ambulance.
AKA long backboards, spine boards, trauma boards.
Dimensions: 6–7\,\text{ft} (≈2\,\text{m}).
Uses:
Supine immobilization for suspected hip, pelvic, spinal, lower-extremity injury, multisystem trauma.
Extrication from confined/awkward spaces.
Features:
Parallel long hand holes 0.5–1\,\text{in} from edge for lifting & strapping.
Materials: legacy marine-plywood (requires infection-control varnish); modern plastic – lighter, non-absorbent.
Definition: relationship between anatomical structures & physical forces during movement.
Weight transfer path (upright): object → shoulder girdle → spine → pelvis → legs.
Key lifting rules:
Keep back straight & vertical; avoid twisting.
Face patient; point feet same direction; pivot with feet, not torso.
Stance: feet shoulder-width (~15\,\text{in}/38\,\text{cm} apart), one slightly forward.
Bend at knees/hips ≤ 90^{\circ}; let leg muscles (powerful, conditioned) do the work.
Keep load close to body; arms nearly adjacent to torso plane.
Distribute weight symmetrically; avoid lateral forces.
Power Lift (Skill Drill 8-1):
Lock back with slight curve, tighten abdominals.
Spread & flex legs.
Palms-up grip, hands just in front of torso plane.
Center load; reposition feet if needed.
Lift by straightening legs, then curling arms if higher elevation needed.
Power Grip:
Hands \ge 10\,\text{in} (25\,\text{cm}) apart, palms up, thumb extended, handle deep into palm.
Avoid palm-down grasp (relies on fingertips; high failure risk).
Keep back locked; no lateral curvature.
Kneel to minimize forward lean; reach only 15–20\,\text{in} (38–50\,\text{cm}) beyond torso.
Pulling sequence: flex arms → reposition body → repeat (prevents jostling & spinal torque).
Bed drags: kneel on bed; use sheet/blanket rolled into 6-inch "handles" to glide patient.
Two-provider side drag technique: each kneels beyond shoulder, grasps armpit + belt, elbows high to minimize trunk rotation.
Log-roll considerations: kneel close; lean from hips; continuous motion until pt braced against thighs.
Diamond Carry (Skill Drill 8-2): 4 providers – head, foot, two sides.
Side providers rotate palms down with head-end hand, release opposite, then turn toward foot; all walk same direction.
One-Handed Carry (Skill Drill 8-3): after initial two-hand lift to waist, providers pivot, switch to outside hand so all face forward.
Weight awareness:
Typical adult 120–220\,\text{lb} (≈54–100\,\text{kg}).
≥250\,\text{lb} (≥114\,\text{kg}) requires ≥4 providers.
Special bariatric resources often >350\,\text{lb} (≈159\,\text{kg}).
Guideline table highlights:
Estimate combined pt + equipment weight.
Communicate; avoid twisting; keep load close; flex knees/hips.
Indications: conscious pt able to sit.
Features: fold-out head/foot handles, safety straps, rear wheels or tracks.
Procedure:
Secure lap, chest, arm/hand, and foot.
Provider positions: head (commander) & foot; optional 3rd for guidance/opening doors.
Roll on landings; carry on steps; transfer to stretcher at bottom.
Indications: unresponsive, supine, spinal, or cannot sit.
Strap high-torso “armpit through” strap to prevent sliding.
Descent/ascent head-high orientation: foot end first going down, head higher than feet.
Strongest providers at head & foot; height differential: shorter at head if stair descent.
Tilt head end into patient compartment; safety bar catches hook.
Side EMT lifts & retracts undercarriage via lock.
Roll fully inside onto all six wheels.
Engage floor/side clamps; verify lock before vehicle movement.
Guidelines (Table 8-2): adequate crew, manufacturer’s instructions, always secure before motion.
Team leader assigns positions, gives overview, uses two-part commands: preparatory + execution (louder).
Countdowns: clarify whether “3” or “lift” is execution word.
Dynamic adjustment: leader may alter sequence as situation evolves.
Minimize total body lifts; use wheels when possible.
Coordinate every lift; ask for help promptly.
Never lift with a curved/twisted back.
Justified for:
Imminent environmental danger (fire, explosion, HAZMAT, traffic, water, structural collapse).
Inability to access other critical pts.
Inability to provide lifesaving care in current position.
Principles:
Prioritize speed over spinal precautions but drag along long axis to limit spinal movement.
Solo drags:
Clothing drag (neck/shoulders; unbutton top two buttons).
Blanket/coat drag.
Arm drag (pt’s arms overhead, rescuer grasps wrists).
Arm-to-arm/under-axilla drag.
Vehicle solo extraction:
Move legs off pedals, against seat.
Rotate pt’s back toward door.
Arms through axillae, grasp wrists; support head on torso; drag out.
If legs snag, lower to ground, clear limbs, long-axis drag away.
Additional one-rescuer techniques: fireman’s carry, pack-strap carry, cradle carry (see Fig 8-17 references).
Draw-Sheet Method (Fig 8-18): roll sheet under pt, slide to stretcher.
Blanket Transfer (Fig 8-20): roll edges for handles; lift as sling.
Scoop Stretcher (Skill Drill 8-11): adjust length → separate halves → slide under each side → lock → secure → move.
Direct Body Carry (chair/bed to stretcher) if pt cannot stand.
Stair-chair transfer from household chairs for conscious pt (Fig 8-21).
Part 1 MVA with overturned sedan in water:
Immediate challenges: unstable vehicle, partial submersion, limited access, two entrapped unrestrained pts, potential hypoxia for Pt 1.
Body mechanics relevance: confined space requires awkward reaches; risk of EMT injury during extrication.
Additional resources: rescue unit for stabilization/extrication, paramedics for ALS airway & oxygen, fire for water hazard.
Part 2 Critical decision-making:
Pt 1 unstable (unresponsive, cyanotic, snoring) → rapid access imperative before full rescue arrival.
Safety & body mechanics: confined ditch, water; plan for minimal-angle pulls, coordinated commands; maintain C-spine.
Removal plan: rapid extrication onto backboard through rear door, simultaneous manual inline stabilization, prioritize airway/oxygen.
Part 3 Implementation:
Half-board wedge technique; firefighter assists; remote holding of other end due to space; use long-axis drag onto board; lift-and-carry mindful of water-filled ditch traction hazards.
Geriatrics: high anxiety, fear of not returning home; fragile bones/skin – avoid skin pulls, use draw sheets, slow deliberate moves.
Technology aids:
Soft stretchers, tarps, sliding transfer boards.
Hydraulic sling lifts (reduce manual lifting).
Bariatric stretchers, ramps, winches for >350\,\text{lb} patients.
Clean/disinfect wooden backboards per protocol; plastic boards preferred.
Maintain stretcher mechanisms per manufacturer; fluid-resistant mattresses mandatory.
Post-call debrief: identify technique gaps, equipment needing service, skills to retrain.
Dual obligation: patient dignity/safety and rescuer occupational safety.
Documentation: chart specific movement methods (e.g., “Pt transferred via draw-sheet lift”); aids QA and legal review.
Continuous training: dynamic weight shifts; rehearse commands & positions with unfamiliar partners.
Stretcher weight: 40–145\,\text{lb}.
Stretcher height range: 12–36\,\text{in}.
Patient torso weight percentage: 68\%-78\%.
Safe reach limit: 15–20\,\text{in} forward.
Standard stance width: 15\,\text{in} (38\,\text{cm}).
Heavy pt threshold: >250\,\text{lb} requires ≥4 rescuers; bariatric resources ≥350\,\text{lb}.
Practice: power lift & grip; diamond/one-hand carries; stair chair sequence; loading stretcher.
Memorize: emergency move indications; weight limits; communication protocol.
Review: infection-control cleaning, geriatric handling considerations.
Reflect: after each transport, debrief to reinforce or adjust technique.
