How to perform a Neurological Assessment

February 22nd, 2020
The skill to perform a Neurological Assessment can be life saving when a victim is suspected of having suffered a stroke, have a head injury , is in a coma or when the diver is suspected of having acute decompression illness.

It is good practice to regard any neurological abnormality after diving as acute decompression illness. Notify a diving medical officer , cal DAN Hotline +27 82 810 6010
With an unconscious diver

Assess:
  • Level of unconsciousness
  • Pupillary responses
  • Pulse rate
  • Blood pressure
  • Respiratory rate
  • Temperature

Use the Glasgow Coma Scale to assess the level of consciousness.
  • A fully conscious victim will score 15 points.
  • A deeply unconscious victim will score three points.
  • Assess the victim's pain responses by firmly squeezing his or her Achilles tendon between your thumb and forefinger for two seconds.
  • A painful stimulus normally causes limb withdrawal from the source of pain as the knee and hip joints flex. This is called a flexion response. If the limb is thrust straight out following a painful stimulus, it is an abnormal “extension to pain” response.
  • All responses must be noted as indicated below.
Repeat all these observations every 15 minutes while consciousness is reduced or confusion and disorientation are present. When the victim is fully conscious, repeat these observations at hourly intervals. Pinpoint or unequal pupil size, slowing of the pulse and respiratory
rate, and an increase in blood pressure indicate increased pressure on the brain.

Instruments required
  • Light source
  • Patellar hammer
  • Cotton wool ball
  • Pin
  • Blunt-pointed object
  • Sphygmomanometer to measure blood pressure
  • Rectal thermometer
  • Timing device
  • Tuning fork
