What is a Traumatic Brain Injury? A traumatic brain injury (TBI) is caused initially by a blow to the head. TBI also includes potential complications seen after the initial injury caused by lack of oxygen to the brain tissues or increased pressure within the skull. A TBI can, therefore, be analysed as three 'injuries': First injury: This is the initial injury occurring in the seconds after the accident. Damage is described as closed, open or crush injuries. Second Injury: This occurs when the oxygen supply to the brain is reduced in the minutes and hours after the accident, worsening the damage already caused by the first injury. This can be caused by an obstruction to an airway or serious blood loss. Third Injury: This occurs as a result of blood leaking from damaged blood vessels, over a period of days or weeks, into the area causing the brain to swell. The skull is a fixed space and the brain can suffer damage if it squeezes against it. If the brain swells it can squeeze the blood vessels, limiting the brain's blood circulation.
