normal mental status
Normal Mental Status
  • Consciousness
    • Person is fully responsive to stimuli and demonstrates awareness of the environment
  • Altered level of consciousness
    • Some form of dysfunction or interruption in the central nervous system
normal mental status7
Normal Mental Status
  • Patient is awake
  • Patient is alert – aware of surroundings
  • Patient is oriented to person, place, & time
  • Patient is cooperative
  • Patient carries on normal conversation
  • Patient able to follow/obey commands
  • Gait is even and steady
altered level of consciousness
Altered Level of Consciousness

Hallmark sign of central nervous system injury or illness

did you know
Did You Know?
  • When perfusion is declining, the first indicator is a changing level of consciousness
  • The last indicator is a falling blood pressure
assessing mental status avpu
Assessing Mental Status - AVPU
  • A – awake
  • V – responds to verbal stimuli
  • P – responds to painful stimuli
  • U- unresponsive
a awake
A – “Awake”
  • Patient is awake, alert and aware of surroundings
  • OR
  • Patient may be awake but confused
    • Report what the patient is oriented to
      • “Oriented to person but not place or time”
  • Key is watching for a change in level of consciousness from the baseline taken
v verbal response
V – Verbal Response
  • This would need to be evaluated prior to touching the “unconscious” patient
  • Problem: If trauma is involved, need to manually control the C-spine before causing the patient any movement of the c-spine
  • If possible, call the patient’s name to check for response to verbal stimuli prior to making physical contact
p painful response
P – Painful Response
  • Does not necessarily mean you have to perform a painful task to check for response
    • Start with simple tactile contact – touch
    • Add deeper stimulation if needed
      • Sternal rub
      • Pinch of thumb web space
      • Trapezius muscle squeeze (near neck)
    • Do not cause so much trauma as to leave marks/bruises
    • Observe for some kind of response with muscles
patient response
Patient Response
  • Patient response can include:
    • Opening of eyelids even briefly
    • Fluttering of eyelids
    • Wrinkling of brows
  • Most important is looking for changes in the patient’s response from one evaluation/assessment to the next
u unresponsive
U - Unresponsive
  • The patient has NO response at all
    • No moaning
    • No muscle twitch at all
      • No eyelid flutter
      • No wrinkling of the eyebrow
    • Muscles are flaccid with absolutely no response regardless of stimuli
neurological exam in the field
Neurological Exam In the Field
  • AVPU – what is level of consciousness?
  • Pupillary response
  • Movement of distal extremities
    • Wiggling fingers and toes
  • Sensation of distal extremities
    • Ability to feel contact with fingers and toes
  • GCS
    • <10 or deteriorating mental status patient is considered critical and categorized as Category I trauma
glasgow coma scale gcs
Glasgow Coma Scale - GCS
  • The best score possible is given
  • More important is watching the trend than relying on any one score

    • Can push you away or grab at the noxious stimuli (IV, collar, bandaging, your hands)
  • 4 – Withdrawal
    • No longer localizing, just withdraws/pulls away to get away from annoying/painful stimuli (IV, collar, bandaging, your hands)
motor cont d
Motor cont’d
  • 3 – Flexion to pain
    • Arms flex/bend slowly toward center of chest when any stimuli applied
