Eye opening - 4
Best Verbal response - 5
Best Motor response - 6
How are the parameters for Glascow Coma Scale scored?

E.g. E2V3M4 = GCS 9
What are the GCS scores for mild, moderate, and severe brain injury?
>13 = Mild
9 to 12 = Moderate
<8 = Severe
How is GCS scored for intubated patients?
Scored with a “T” bc no verbal response (intubated)
Min - 2T
Max - 10T
Delirium or Dementia?
Richmond Agitation-Sedation Score
Delirium
What is the purpose of using the Richmond Agitation-Sedation Score?
Screen level of alertness in a mechanically ventilated patient
Used before CAM-ICU or bCAM in Delirium Triage Screen
Delirium or Dementia?
Confusion Assessment Method (CAM)
Delirium
What screening test allows non-psychiatrists to detect delirium in high risk environments?
Confusion Assessment Method (CAM)
What are the 4 features required for a positive CAM?
1 - Acute onset and fluctuating course
2 - Inattention
3 - Altered Level of Consciousness
4 - Disorganized thinking
Must have features 1 AND 2 + either 3 OR 4
What are the 3 steps to performing the Richmond Agitation-Sedation Scale?
- Observe pt. Are they alert and calm (score 0)? Agitated/combative (+)? Difficult to arouse (-)?
- If pt not alert, loudly state pt’s name and direct them to open eyes and look at speaker.

+2 - Agitated, frequent nonpurposeful movement
+1 - Restless, anxious
How are the negative scores of the Richmond Agitation-Sedation Scale described?

- 2: Light sedation, <10 sec awakens with eye contact to voice
- 3: Mod sedation, Any movement to voice (no eye contact)
- 4: Deep sedation, no response to voice but responds to physical stimulation
- 5: Unarousable, no response to any stimulation
