Can a head sensor and eye ultrasound spot brain pressure in the ambulance?

This trial tests whether two non-invasive tools can help paramedics detect dangerously high pressure inside the skull in patients with sudden brain injury, such as stroke or head trauma, before they reach the hospital. The tools are a wearable sensor placed on the head and an ultrasound measurement of the eye's optic nerve, both avoiding needles or incisions. The study will compare how accurately these tools identify patients needing specialized brain surgery, potentially improving triage and outcomes.
