Abstract
The advantages of the P-50 Transducer for monitoring intracranial pressure are easy attachment, simplified zero point determination and easy calibration similar to recording methods for electrocardiograms and respiration. The P-50 transducer is a semiconductor strain gauge transducer which was originally developed for determining blood pressure. By attaching a foot plate, the applanation principle could be applied and pressure determinations from the anterior fontanelle were feasible. The accuracy of this device was confirmed in several experiments. As a semiconductor strain gauge, it was extremely light, which is necessary for continuous measurement. Although some problems remain to be solved in regard to its fixation on the subject, this device should be clinically acceptable as a system for monitoring intracranial pressure.
