[Continuous registration of intracranial pressure using disposable transducers].

The authors report the results of physical tests (baseline drift, temperature drift, absolute accuracy) and clinical experiences in intraventricular intracranial pressure monitoring with disposable transducers. Physical tests gave excellent results concerning baseline drift (less than 1%), temperature drift (0.35 mmHg/degrees C), and absolute accuracy (+/- 2 mmHg) in the range of intracranial pressure of both transducers tested (Gould DTX and Cobe 41-500). Clinical testing gave corresponding values compared with routine methods of ventricular pressure monitoring via a Bentley-Trantec-Transducer. As a result of the study disposable pressure transducers are recommended for routine use in clinical practice of intraventricular intracranial pressure monitoring.
