By ROS (reactive oxygen species)
And Pro-inflammatory cytokines

Question 4

Name 2 systemic contributions to secondary brain injury

Answer 4

Hypotension
hypoxia
hypo/hyperglycaemia
hypo/hypercapnia
hyperthermia

Question 5

What makes up the initaial neurologic assessment

Answer 5

consciousness
breathing pattern
pupil size and responsiveness
ocular position and movements
skeletal motor responses

Question 6

What is MGCS

Answer 6

modified glasgow coma scale- evaluates the neurological function
higher scores correlates with a better prognosis

Level of consciousness most reliable measure o impaired cerebral function

Answer 7

cerebral oedema formation
increased intracranial pressure
compromised to the blood-brain barrier
alterations in cerebrovascular reactivity
