This manuscript presents an analysis of different intracranial pressure (ICP) non-invasive monitoring devices. External ventricular drainage still remains a "gold standard" оf neuromonitoring, but this manipulation can be not always feasible, because of contra-indications or absence of neurosurgery in this hospital. Also there is a risk of development infections or hemorrhage. In these conditions the great value is got by development of ways of non-invasive definition of VChD which would allow to carry out safe and, if necessary, numerous measurement of this parameter. Now, the leading place is occupied by various ultrasonic and telemetric methods. The question of accuracy of received data at non-invasive methods remains open and demands further specification.
