light extrication
1
Personnel
• Every ambulance must be staffed with at least one EMT-B in the patient compartment during patient transport.
• Two EMTs are strongly recommended.
• Some services may operate with a non-EMT driver.
1
Inspections and Safety Precautions • Being fully prepared means inspecting
the ambulance and equipment daily. • Check medical equipment and supplies
at least daily. • Review standard traffic safety rules and
regulations.• Make sure seat belts work and that
oxygen tanks are secured.
1
Dispatch PhaseThe dispatcher should gather minimum information such as:
• Nature of the call• Name, person, location, and call-
back number• Location of the patient(s)• Number of patients and idea of the
severity of their conditions• Special problems or other pertinent
information
1
En Route to the Scene
• Fasten your seat belt.
• Confirm response and location.
• Prepare for arrival.
• Decide what equipment to take initially.
1
Arrival at the Scene
• Scene safety
• Safe parking
• Traffic control
1
• Look for safety hazards. • Evaluate need for additional units. • Determine MOI/NOI. • Evaluate spinal precautions. • Follow BSI precautions.
1 Scene Size-up
Safe Parking and Traffic Control • Park away from hazards and out of
flow of traffic. • Do not block other responding EMS
vehicles. • Place appropriate warning devices
on both sides of the accident.
1
Transfer Phase
• Provide lifesaving treatment.• Package patient for transport.• Be sure to secure the patient with
at least three straps across the body.
1
Transport Phase
• Inform dispatch when you are ready to leave the scene.
• Report the number of patients and the name of receiving hospital.
• Conduct ongoing assessments.• Contact medical control.
– Report number of patients– Nature of problems
1
Delivery Phase• Report arrival to dispatch.
• Give report to staff.
• Physically transfer the patient.
• Complete written report.
• Leave a copy with an appropriate staff member.
1
En Route to the Station• Inform dispatch
whether or not you are in service and where you are going.
• Clean and disinfect the ambulance and any equipment used.
• Restock supplies.
1
Postrun Phase
• Complete and file any additional written reports.
• Inform dispatch of your status, location, and availability.
• Clean and restock the ambulance.
1
Defensive Driving • 6,000 ambulances involved in crashes every
year • 300 fatalities between 1991 and 2001• Properly operating the ambulance is as
important as taking care of patients.
1
Driver Characteristics
Physical fitness• Effects of medication• Fatigue
Emotional fitness• Maturity and stability• Proper attitude
1
As a public servant, your actions will be scrutinized.
As a public servant, your actions will be scrutinized.
Safe Driving Practices
• Speed does not save lives; good care does.
• Seat belts must be worn. • Learn how your vehicle
accelerates, corners, sways, and stops.
1
Driver Anticipation
• Anticipate the actions of other motorists and pedestrians.
• Assume actions of other drivers will cause a collision.
• Use of PA system may add to confusion.
1
Cushion of Safety
• Keep safe following distance. • Watch for tailgaters. • Be aware of blind spots. • Use a spotter when backing up.
1
Excessive Speed
• Speeding is unnecessary if patient is properly assessed and stabilized.
• Decreases reaction time• Increases stopping time and
distance
1
Vehicle Size and Cornering • Vehicle length and width are
critical factors in maneuvering. • Vehicle size and weight greatly
influence braking and stopping distances.
• Always be aware of your position on the roadway.
• Take corners at the speed that will put you in the proper road position as you exit the curve.
1
Weather and Road Conditions Be alert to changing conditions. Decrease speed and increase distance in poor conditions, such as:
• Hydroplaning• Water on roadway• Decreased visibility• Ice and slippery surfaces
1
Laws and Regulations
• Vary from state to state• EMS drivers have certain limited
privileges. • These privileges do not lessen
drivers’ liability.
1
Warning Lights and Sirens
• Must be responding to an emergency
• Use both audible and visual devices.
• Operate with due regard.
1
Right-of-Way Privileges
• You must not endanger people or property under any circumstances.
• Know your local right-of-way privileges.
• Exercise them only when necessary for the patient’s well-being.
1
Escorts and Intersection Hazards Use of escorts
• A dangerous practice• Follow escorts at a safe distance.
Intersection hazards• Most common place for collisions• Even on urgent calls, come to a
momentary stop at the light.
1
Air Ambulances
Fixed wing
• Interhospital transfers
Rotary-wing
• Used for shorter distances
1
Medivac Operations
Become familiar with local capabilities. Calling for a medivac:
• Ground transport would take too long.
• Spinal cord injuries, amputations, burns, diving emergencies, venomous bites
Notify your dispatcher first.
1
Establishing a Landing Zone
• Area should be hard or grassy level surface that measures 100' x 100' (recommended)
• Clear area of loose debris and survey for overhead or tall hazards.
• Mark landing site with weighted cones or headlights.
1
Safety Precautions• Do nothing near the helicopter and only go
to where the crew or pilot directs you.• Keep a safe distance away from the aircraft.• Stay away from the tail rotor.• Never approach the helicopter from the rear.
1
Special ConsiderationsNighttime landings
• Considerably more dangerous than daytime operations
Landing on uneven ground• Main rotor blade will be closer to the
ground on uphill side. Hazardous materials incidents
• Land zone should be upwind and uphill.

Removal of the motor vehicle from around the patient.
Removal of the motor vehicle from around the patient.
Removal and Transfer
• Determine urgency of move.• Plan moves and communicate with the
team.• Once patient is freed, rapidly reassess
and recheck vital signs.• Make certain spine is immobilized.
2
Removal and Transfer, cont'd• Move the patient in slow,
controlled steps.• Choose a path that requires the
least manipulation of the patient and equipment.
• Move the patient as a unit.• If the patient’s condition is critical,
perform remaining steps en route.

NIMS
National Incident Management System
3
Nationwide model to enable federal, state, and local governments and private-sector and non-governmental organizations to work together in an emergency.
• Applicable to all jurisdictions• Utilized by a variety of disciplines • Improves coordination and cooperation • Built on existing incident management
systems
3 NIMS, continued
Mass-Casualty Incidents • Incidents
involving three or more patients
• Places high demand on available resources
• May require mutual aid response
3
Triage
• Triage is the sorting of two or more patients based on the severity of their conditions.
• Patients are ranked in the order of the severity of their conditions.
• Treatment priority is determined by rank.
3
Triage is an essential component of operations at a mass-casualty incident.
3 Triage, continued
Triage Categories 3
Triage Priorities
• Patients should be color coded early. • Patients tagged red should be assessed
in the treatment area. • Patients in dangerous areas should be
removed to a non-hazardous environment prior to triage.
3
Triage Procedures• Rotate hospital
destinations. • Trauma center
should receive the most critical patients.
• Utilize a transport officer to evenly distribute patients.
3
Disaster Management
• The role of the EMT-B is to respond when requested and report to incident command.
• A casualty collection area may be set up and staffed by nursing and medical staff with equipment.
• You may have to bring patients to this area.
3
Introduction to HazMat
• Any substance that is toxic, poisonous, radioactive, flammable, or explosive and can cause injury or death with exposure
• Responders must have special training before becoming involved with hazardous materials.
3
Hazardous Materials Situations• A train or truck with a leaking substance• A leak, fire, or other emergency at an
industrial plant, refinery, or other storage facility
• A gas pipe leak or rupture• Deterioration of underground fuel tanks• Buildup of methane in sewers• Car crash involving a ruptured gas tank
3
Recognizing Hazardous Materials• Warning signs• Placards• Labels
3
• Visible cloud or odd-looking smoke coming from an escaping substance
• A leak or spill from a tank, container, truck, or railroad car
• An unusually strong, noxious, acrid odor
3Recognizing Hazardous Materials
HazMat Placards
The four-digit number on the warning placard identifies the hazardous material.
3
First Arrival
• Stop at safe distance.• Call for a HazMat team.• Stay out of danger zone.• Gather information. • Do not reenter the scene.• Do not leave until cleared by HazMat.
3
Identifying Hazardous Materials• Safety perimeters• Uphill and upwind• Efforts to ensure safety and survival
of the masses.
3
Approach a hazardous incident cautiously from upwind.
HazMat Scene Safety3
HazMat Scene Operations • HazMat will determine the specific
hazardous material involved.• Only those trained in HazMat and
wearing protective gear should enter the zone.
• As an EMT-B, your job is to remain in the designated treatment area.
• HazMat will bring patients to you.
3
Decontamination Area
• Designated area where contaminates are removed.
• Anyone who leaves the hazard zone must pass through this area.
• Wait for the patients to be brought to you.
3
Treating Patients at a HazMat Incident
• Only essential treatment will take place in the hazard zone and decontamination area.
• Injuries should be treated as any other patient.
• Treatment for exposure will be mainly supportive.
• Initiate transport.
3
Special Care
• Some patients may need to be treated without full decontamination.
• Protect yourself with proper gear.• Ensure the receiving hospital is
aware patient has not been fully decontaminated.
• Ambulance will need to be decontaminated after transport.
