Proper first aid for traumatic head injuries to manage concussion symptoms and recognize signs of brain injury.
Head injuries can be deceptively severe. Call 911 / 112 immediately if the person has lost consciousness (even briefly), is vomiting repeatedly, has unequal pupil sizes, is extremely confused, or has clear fluid/blood leaking from their nose or ears.
Check if the person is responsive. Ask simple questions: "What is your name?", "What day is it?", "Do you know where we are?". Monitor for confusion, memory loss, or extreme drowsiness.
If the injury resulted from a fall, car crash, or high-impact collision, assume a neck or spinal injury. Keep the person completely still. Do not move them unless they are in immediate danger.
If there is an open cut, apply firm, direct pressure with a clean cloth. Caution: Do not apply pressure directly if you suspect a skull fracture (if the bone feels soft, depressed, or bone fragments are visible).
Apply a cold pack or ice wrapped in a cloth to any bumps or swollen areas for 10 to 20 minutes to reduce inflammation. Never place ice directly on the skin.
Observe the eyes for unequal pupil sizes (anisocoria). Watch for slurred speech, double vision, coordination loss, or weakness in limbs.
Observe the person continuously. Do not leave them alone. Do not give aspirin or ibuprofen immediately as they can increase bleeding risk (use acetaminophen if cleared by a doctor).
