Brain Tissue Oxygen SensorsThe brain tissue oxygen sensor is a recent development. The device is screwed into the skull in the same manner as the bolt; however, the sensor catheter is an electrochemical oxygen–tension sensitive membrane. A single bolt can be designed to accept a pressure sensor, oxygen sensor, and brain temperature sensor. Patients with severe brain injury due to trauma or aneurysmal hemorrhage may benefit from placement of these three sensors and a ventriculostomy to drain CSF for control of ICP. This requires two twist-drill holes, which may be adjacent or on opposite sides of the head.
