Why Unconscious Patients Are a Red Flag in Car Crashes
A patient who loses consciousness at a crash scene almost always signals either a direct head impact or a sudden, forceful stop that shakes the brain inside the skull. On a highway like NH-101, where posted speeds run 55 mph or higher, that kind of jolt happens even when a vehicle doesn't visibly crumple. Responders treat any unresponsive patient as a possible traumatic brain injury or internal injury until a hospital evaluation says otherwise.
Seat belts and airbags change the outcome of that same jolt, but they don't erase it. A belted occupant is held in place so the body decelerates with the vehicle instead of continuing forward into the dash or windshield, which cuts the risk of the head or chest striking something hard. Airbags add a cushion for that remaining forward motion. Neither feature, though, stops the brain from moving inside the skull during a hard stop, which is why head injuries and loss of consciousness still turn up in belted, airbag-equipped crashes.
According to the National Highway Traffic Safety Administration, an estimated 1,947,298 passenger-vehicle occupants were injured in motor-vehicle traffic crashes in 2023. That volume is one reason investigators and EMS crews default to caution: a patient who seems stable on first glance can still have injuries that only show up once swelling or internal bleeding progresses.
Frequently Asked Questions
What should I do if I'm involved in a car accident?
Call 911, stay where it's safe to do so, and avoid moving anyone who may have a head, neck, or back injury unless there's an immediate danger like fire. Exchange information with other drivers if you're able, and let police document the scene.
What are the most common injuries in car accidents?
Head and neck injuries, broken bones, and chest or abdominal trauma are frequently reported, along with cuts and bruising from broken glass or impact with the interior of the vehicle. Loss of consciousness can point to a more serious head injury that needs immediate evaluation.
What typically causes crashes like this one?
Common factors include speed, distraction, impaired driving, and road or weather conditions. Investigators generally review vehicle data, witness accounts, and the scene itself before determining a cause.
Does speed make a crash more dangerous?
Yes. Higher speeds mean more force at impact and less time for a driver to react or stop, which raises both the likelihood and severity of injury.
What to Do After a Car Accident in Brentwood, NH
If you're involved in a crash in Brentwood, get checked out by a medical provider even if you feel fine at the scene, since some injuries, especially to the head or neck, don't show symptoms right away. Keep a copy of the police report and any medical records in case you need them later.
Report the crash to your insurance company as soon as you reasonably can, and take photos of the scene and any visible damage if it's safe to do so. Giving yourself time to rest and follow up with a doctor matters as much as the paperwork.
