(159 cards)
scene size-up
steps taken when approaching the scene
(checking scene safety, taking standard precautions, noting injury)
Nature of the call
Determining why EMS has been called
– Mechanism of injury
– Nature of illness
Mechanism of Injury
- Force(s) that may have caused injury
- Understanding forces can predict injury patterns.
- Can be very useful in predicting injuries associated with
certain types of motor vehicle crashes
Mechanism of Injury
* Motor-vehicle collisions
– Head-on collisions
▪ Up-and-over injury pattern
▪ Down-and-under injury pattern
clues of this can be windshield damage
– Rear-end collisions
– Side-impact collisions (broadside or “T-bone”)
– Rollover collisions
– Rotational impact collisions
▪ Cars are struck then spin.
▪ Initial impact often causes subsequent impacts.
Mechanism of Injury
Falls
– Adult
▪ More than twenty feet
– Child under fifteen years
▪ More than ten feet (two to three times child’s height)
What are the steps of scene size-up?
- Check scene safety
- Taking standard precautions (BSI)
- Note mechanism of injury or nature of illness
- Determine number of patients
- Decide what additional resources are needed
What should you do when approaching the scene?
- Look and listen for other emergency vehicles
- Look for signs of collision-related power outages
- Look for traffic flow
- Look for smoke in the direction of the collision
What should you do when within the sight of the scene?
- Look for things that signify HAZMAT
- Look for collision victims on/near road
- Look for smoke
- Look for broken utility poles and downed wires
- Look for people walking around scene
- Look for signals of police and other EMS providers
What should you do as you reach the scene?
- Wear appropriate PPE
- Follow instructions of incident commander
How should you establish the danger zone?
Evaluate hazard and restrict it based on on threat level (different levels of danger require bigger danger zones)
What should you do when there are downed power lines?
Establish the danger zone beyond each intact pole for a full span and to the sides for the distance that the severed wires could reach. Stay out of danger zone until utility company has deactivated the wires or rescuers have moved and anchored them.
What should you do when a vehicle is on fire (no other hazards involved)?
Park ambulance at least 100 feet away and park upwind
What should you do when there is hazardous material threatened by a fire?
The size of danger zone is determined by the type of material. Use binoculars to read the placard on the truck and refer to Emergency Response Guidebook. Park upwind.
What should you do when there is spilled fuel?
Park upwind from direction of spill. If not possible, park as far away from possible, avoiding anything that may carry the spill to the parking site.
How hot is the ambulances catalytic converter?
1,000 F
What should you do when there is HAZMAT?
Park upwind. If the type of material is known, seek advice through CHEMTREC through the incident commander
What should you look for when evaluating for threat of violence?
- Fighting/Loud voices
- Weapons
- Signs of alcohol/drug use
- Unusual silence
- Knowledge of prior violence
What is the nature of the call?
Why EMS has been called
1. Mechanism of injury
2. Nature of illness
What is the mechanism of injury?
The forces that caused the injury (can predict possible injuries)
What injuries often occur in a head-on collision?
Up and Over injury pattern
Down and Under injury pattern
What are the types of motor vehicle collisions?
Head-on
Rear-end
Rollover
Rotational
What 5 things should you look for in any motor vehicle accident?
- Ejection
- Deformaties in the vehicle
- Amount of vehicle deformities
- Seatbelt use
- Airbag deployment
What is considered a severe fall?
Adults: More than 20 feet
Children under 15: More than 10 feet or 2-3X child’s hight
What are 4 important factors to consider regarding falls?
- Hight which the patient fell from
- Surface patient fell onto
- Part of patient that hit the ground
- Anything that interrupted fall
