Abstract
A method and apparatus for predicting the outcome of head injury trauma by monitoring cerebrospinal fluid (CSF) characteristics, preferably by monitoring the pH of CSF. The apparatus includes a catheter with a wall section adapted to permit CSF to flow therein, and a sensor located within the catheter such that the CSF is permitted to flow adjacent the tip of the sensor.
