Level Of Arousal In Coma : How To Remember Easily ?

  • C – Cotton wisp: Tickling the nostrils with a cotton wisp is a moderate stimulus to arousal—all but deeply stuporous and comatose patients will move the head away and arouse to some degree.
  • O – Offending stimulus: An even greater degree of responsiveness is present if the patient uses his hand to remove an offending stimulus.
  • M – Motor response: A sequence of increasingly intense stimuli is first used to determine the threshold for arousal and the motor response of each side of the body.
  • A – Abduction withdrawal: Pinching the skin causes ecchymoses and is generally not performed but may be useful in eliciting abduction withdrawal movements of the limbs.
  • A – Abduction-avoidance movement: Posturing in response to noxious stimuli indicates severe damage to the corticospinal system, whereas abduction-avoidance movement of a limb is usually purposeful and denotes an intact corticospinal system.
  • R – Results of testing: The results of testing may vary from minute to minute, and serial examinations are useful.
  • O – One-sided posturing: Posturing may also be unilateral and coexist with purposeful limb movements, reflecting incomplete damage to the motor system.
  • U – Useful examinations: Tickling the nostrils, pressure on bony prominences, and pinprick stimulation are humane forms of noxious stimuli, and serial examinations are useful.
  • S – Stimuli intensity: A sequence of increasingly intense stimuli is first used to determine the threshold for arousal and the motor response of each side of the body.
  • A – Arousal variations: The results of testing may vary from minute to minute, and serial examinations are useful.
  • L – Limb movements: Pinching the skin causes ecchymoses and is generally not performed but may be useful in eliciting abduction withdrawal movements of the limbs.
