| Cushing's triad | □ heart rate up and down □ widen pulse pressure □ irregular respirations ® then chain stokes ◊ slow shallow uneven then apnea episodes |
| § Posturing | □ Decorticate - in to the core □ Decerebrate - |
| * Tests that determine underlying cause of IICP: | ○ CT scan 10-15 min ○ MRI ○ Lumbar puncture ○ Intracranial pressure monitor ○ Do a good assessment -can tell how they are doing by a good neuro assessment |
