    Study Notes

    Scene Size Up Overview

    • Scene size up includes evaluating safety hazards, taking standard precautions, determining mechanism of injury versus nature of illness, assessing number of patients, and identifying need for additional resources.
    • It is an ongoing process throughout the emergency call, requiring continuous assessment of changing situations.

    Scene Safety

    • Scene safety ensures the well-being of EMTs and involves assessing potential hazards to oneself, crew, patients, and bystanders.
    • Elements of scene safety include protecting bystanders and refraining from entering unsafe scenes; calling for assistance if the scene needs to be made safe.
    • A danger zone extends 50 feet around a scene; increase to 100 feet if a vehicle is on fire or if hazardous materials are involved.

    Mechanism of Injury

    • Mechanism of injury pertains to the physical event causing an injury, with factors including the type of collision (head-on, rear impact, etc.), forces involved, and specifics like seatbelt use.
    • Injuries from falls must consider the distance fallen, surface type, and if anything broke the fall.

    Standard Precautions

    • Standard precautions are essential to prevent exposure to bodily fluids and include anticipating needs, keeping equipment ready, and using appropriate protective gear (gloves, masks, gowns).
    • Key elements of body substance isolation involve having personal protective equipment accessible and recognizing potential hazards.

    Types of Trauma and Injuries

    • Blunt force trauma results from non-penetrating impacts, leading to abrasions, bruises, and fractures, while penetrating trauma occurs when objects penetrate the skin.
    • Velocity of trauma is categorized into low (knives), medium (handguns), and high (rifles), with each type associated with different injury patterns.

    Information Gathering

    • Sources for understanding the mechanism of injury include the patient, family, bystanders, and scene observations.
    • Medical history and context for nature of illness can be gathered from the patient, family, bystanders, and examining the scene.

    Evaluating Resource Adequacy

    • Determining resource adequacy involves assessing the number of patients, hazardous materials, potential fire or rescue requirements, and unusual circumstances.
    • Call for assistance and apply triage procedures when more resources are necessary before beginning care.

    Signs of Violence

    • Indicators of potential violence include fighting, loud voices, visible weapons, signs of substance abuse, unusual silence, and knowledge of previous violent incidents.

    Vehicle Collision Insights

    • Rollover collisions are considered the most serious due to the risk of multiple impacts and potential ejections for unrestrained passengers.
    • Understanding injury mechanisms and patterns related to vehicle collisions aids in predicting and managing patient care during EMS response.

    Educational Tools and Resources

    • CHEMTREC provides advice on hazardous materials, while the North American Emergency Response Guidebook offers quick information for identifying risks related to hazardous materials.

    Conclusion

    • Personal safety is the top priority during scene sizeup; continuous monitoring and a proactive approach to assessing the environment, patient needs, and resource requirements are essential for effective emergency response.
