    Study Notes

    Rollover Crashes

    • Ejection or partial ejection of a driver in a rollover crash significantly increases the risk of serious injury or death.

    Trauma Center Criteria

    • Adult trauma patients should be taken to the highest level trauma center if they have a GCS score of 13 or lower due to trauma.

    Airbags

    • Airbags primarily decrease the severity of deceleration injuries during an accident.

    Vehicle Extrication

    • Evaluating the interior of a crashed vehicle helps EMTs identify contact points, allowing for better predictions of potential injuries.

    Fall Assessment

    • Key factors in assessing injuries from falls include the primary impact point, height of the fall, and surface struck, but not the speed of the fall.

    Definition of Work

    • Work is defined as force acting over a distance in mechanical terms.

    Trauma Assessment in Vehicle Crashes

    • If fatalities occur in a vehicle crash, EMTs should assume that all surviving occupants could have sustained serious trauma.

    Level I Trauma Center

    • A Level I trauma center must have general surgeons available 24/7, unlike Level III centers.

    Gunshot Wounds

    • Predicting internal injuries from gunshot wounds is complex due to the potential tumbling or ricocheting of bullets within the body.

    Pulmonary Blast Injury

    • Coughing up blood is a key sign of a pulmonary blast injury.

    Kinetic Energy

    • Kinetic energy refers to the energy possessed by a moving object.

    Index of Suspicion

    • The index of suspicion involves awareness and concern for underlying serious injuries that may not be immediately obvious.

    Cavitation

    • Cavitation describes the phenomenon of pressure waves created by a bullet causing damage apart from its direct path.

    Elderly Fall Assessment

    • Osteoporosis in elderly patients may result in fractures even from minor falls, highlighting the need for careful assessment.

    Mechanism of Injury

    • Information gathered about the damage to a crashed vehicle aids in understanding the mechanism of injury.

    Kinetic Energy and Speed

    • Doubling the speed of a vehicle results in quadrupling its kinetic energy due to the relationship governed by physics.

    Pulmonary Blast Injury Treatment

    • Care for patients with pulmonary blast injuries should include avoiding oxygen administration under positive pressure.

    High-Energy Trauma Indicators

    • Deployment of airbags is less indicative of high-energy trauma compared to signs like vehicle intrusion or deformed structures.

    Critical Interventions in Multisystem Trauma

    • Rapid transport to a trauma center is crucial for improving outcomes in patients with multisystem trauma.

    Second Collision Effects

    • The direct outcome of the second collision in a motor vehicle crash often results in a deformed steering wheel, indicating significant driver impact.
