Another sign of TBI is unequal/unreactive or dilated pupils (Leon-Villapalos, 2012). Tom’s pupils were found …show more content…
A primary brain injury is the damage to the brain at the moment of impact (Tran, 2014). This damage to the brain initiates oedema, inflammation and ischemia which if not controlled could lead to a secondary brain injury (Tran, 2014). If these factors are not controlled they may worsen the secondary brain injury by further disrupting cerebral blood flow (CBF), supply of oxygen and glucose to support cerebral metabolic activity and homeostasis (Leon-Villapalos, 2012). The brain requires a constant energy supply as it has a high metabolic activity. For the brain to have a normal neuronal function is needs a constant supply of oxygen and glucose delivered by the cerebral supply (Leon-Villapalos). When Tom hit his head on the cement footpath he acquired a primary brain injury, Tom’s body is still compensating and has not yet preceded to a secondary brain
