NCT02404740

Brief Summary

Using a pulse oximeter, we have developed an algorithm that estimates intracranial pressure (ICP) based on patients who have had traumatic brain injuries. Patients with hydrocephalus are typically treated with a shunt in order to reduce ICP. At times the shunt can malfunction. We believe that our algorithm will help identify when a hydrocephalus patient's shunt has malfunctioned.

Study Arms (3)

VP shunt functioning

No intervention, just a physiological category--patients with VP shunts that are functioning normally.

Device: Pulse oximetry

VP shunt malfunctioning

No intervention, just a physiological category--patients with VP shunts that are malfunctioning.

Device: Pulse oximetry

No known intracranial pathology

No intervention, just a physiological category--patients without VP shunts that have no known intracranial pathology.

Device: Pulse oximetry
