The device for non-invasive monitoring of intracranial pressure (1) includes a measuring mat (2), processor unit (3), device for recording electrical activity of the heart (4), device for invasive measurement of arterial blood pressure (5), imaging device 6 and network connector (7). The measuring mat includes the processor unit (3) and sensors, at least one sensor (8) monitoring mechanical movement caused by the bloodstream dynamics. The ICP calculation methods use the Windkessel model and the relation between the start of the R-wave and the time delay of the mechanical movement of the head, which is related to the reflection of the pulse wave in the head.
