Study Notes
Scene Size-up Overview
- Scene size-up is the initial evaluation conducted by EMTs upon arriving at a scene.
- Key goals include identifying hazards for safety, understanding the reason for the call, and assessing the need for additional assistance based on patient numbers or other unusual factors.
Safety Precautions at Potentially Dangerous Scenes
- Extra caution is necessary at unstable scenes, such as crash sites or crime scenes.
- Avoid entering dangerous areas; retreat if the scene becomes hazardous.
- Always carry a portable radio and request help if facing situations beyond your training.
Managing Patients Near Moving Traffic
- Limit exposure to traffic by minimizing time spent on scene.
- Traffic shutdown may be necessary for safety.
- Use flares or cones to alert oncoming traffic well in advance.
- Place emergency vehicles strategically to shield the scene.
- Wear bright reflective clothing to ensure high visibility.
- Work as far as possible from traffic flow and remain aware of surrounding vehicles.
Confined Space Considerations
- Approach confined spaces (like caves or sewers) with extreme caution.
- Risks include low oxygen levels and exposure to toxic substances (e.g., methane).
Approaching Suspected Crime Scenes
- Avoid the main sidewalk and opt for grass to minimize visibility to potential threats.
- Walk in a single file with the lead person holding a flashlight to the side.
- Look for cover or concealment while approaching.
- Change positions to survey the surroundings before entering.
- Stand beside the door knob when knocking and reassess conditions before entering.
Patient Problem Assessment During Scene Size-up
- EMTs must classify the nature of the patient's issue as either trauma or medical during initial evaluation.
Understanding Mechanism of Injury
- Mechanism of injury refers to how the patient sustained injuries, including the force’s strength, direction, and nature.
Identifying Mechanism of Injury in Auto Crashes
- EMTs should observe indicators like significant vehicle deformation (greater than 20 inches) and intrusion into the vehicle to assess the mechanism of injury effectively.
