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.
