Extrication equipment • Equipment needed for simple, 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 nonEMT 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 Phase The 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 Scene Size-up • • • • • Look for safety hazards. Evaluate need for additional units. Determine MOI/NOI. Evaluate spinal precautions. Follow BSI precautions. 1 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 As a public servant, your actions will be scrutinized. 1 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 Considerations Nighttime landings • Considerably more dangerous than daytime operations Landing on uneven ground • Main rotor blade will be closer to the ground on uphill side.
