A Novel External Ventricular Drain Sensor to Improve Acquired Brain Injury Monitoring.

We successfully captured an important aspect of the ICP monitoring context, the EVD stopcock position, and time-synchronized it with the recorded physiology. Our system enables future investigations into the impact that a broad contextual data environment has on physiological measurements and acquired brain injury patient outcomes. In the future, we aim to capture additional contextual data sources and expand the scope to battlefield environments.
