The ability to easily determine ventricular pressure in a shunt-treated hydrocephalic patient would allow an immediate check of shunt function and valve regulating characteristics. Ideally any pressure monitoring system should be accurate and stable over prolonged periods, capable of continuous recording with rapid response, and non-invasive. The device we shall describe fulfills these criteria. Several telemetric intracranial pressure (ICP) monitoring devices have been devised. The principal difficulty has been drift of sensitivity and zero baseline with time. The first system to overcome these problems was that of ZERVAS and COSMAN (2). Using the same measurement principle, the sensor described here is used in shunt systems (1).
