Using low power infra red light to measure ICP

Crainio sets out to revolutionise how we measure ICP by developing a non-invasive, inexpensive measurement instrument that uses a simple probe attached to the patient’s forehead. Since our skull and tissue are translucent to light of certain frequencies, it’s possible to use photoplethysmography (PPG) to pick up pulse signals of the brain by shining low-power infrared light at the scalp. Crainio then picks up minute reflections from the surface of the brain. The information in this signal, processed with trained machine learning algorithms, tells us the pressure in the brain, whether it is rising and so the severity of any brain injury. This will ensure that patients with TBI receive the correct treatment without the need for the current invasive probes.
