What is a coma?
a possible consequence of a TBI. A loss of consciousness for more than a concussion
Explain the alexander 6 point scale of recovery levels
1: coma
2: unresponsive vigilance
3: mute responsiveness
4: confusional state
5: independent self care
6: intellectual indepence
Explain the Ranchos levels
1: unresponsive
2: generalized response, inconsistent reaction (often stereotypic)
3: localized response
4: confused and agitated, possible confabulation
5. confused, inappropriate, non-agitated
6. confused, appropriate, comprehension is coming along
7. automatic, appropriate, patient is becoming more independent in self care
8. purposeful, appropriate
explain the Glasgow outcome scale
1=death 2= persistent vegetative state 3=severe disability 4=moderate disability 5=good recovery
