In Colorado, we tend to spend a lot of time outdoors – biking, hiking, skiing, climbing. If you're miles from the trailhead and your mountain biking partner hits their head… do you know what to look out for?
First: Stay calm, keep them still for a moment and ask simple questions.
Look out for:
- Confusion
- A headache that gets worse
- Nausea/vomiting
- Unusual drowsiness
If symptoms are worsening or severe, it’s time to take action. Start heading off the trail and seek medical care if they have:
- Repeated vomiting
- Increasing confusion
- Severe headache
- Difficulty walking or speaking
If you're too far away from the trail and unsure if you should call for help, you should use your SOS device or call 911 if they have:
- Loss of consciousness
- Seizures
- Unequal pupils
- Trouble waking up
- Neck pain or inability to move safely
Head injuries in the backcountry can be hard to assess, especially when adrenaline is running and symptoms develop slowly. But knowing the warning signs of a concussion or more serious brain injury can help you decide when it’s time to get off the trail or call for rescue.
