Abstract

The Neurovent-P-tel sensor is a promising device for telemetric intracranial pressure (ICP) measurements in cases of complex hydrocephalus. Data on its accuracy within a broad ICP range are missing. We applied a porcine model for large-scale manipulation of the ICP values. The telemetric ICP sensor was referenced against ICP values measured directly from a water column within a riser tube. A total of 34 comparative ICP measurements within an ICP range from 2 cm H2O to 31 mm Hg were performed. The mean difference between both measurement techniques was 0.4 mm Hg. The limits of agreement, where 95% of differences between both methods are expected, were from -2.4 to 3.1 mm Hg. The telemetric Neurovent-P-tel sensor system provides good accuracy within a broad range exceeding normal ICP values and might be useful in clinical practice.

摘要

Neurovent-P-tel传感器是一种很有前景的设备，可用于在复杂脑积水病例中进行遥测颅内压（ICP）测量。目前尚缺乏其在广泛ICP范围内准确性的数据。我们应用了猪模型来大规模操纵ICP值。将遥测ICP传感器与直接从立管内水柱测量的ICP值进行比对。在2 cm H2O至31 mm Hg的ICP范围内总共进行了34次对比ICP测量。两种测量技术之间的平均差异为0.4 mm Hg。一致性界限（预计两种方法之间95%的差异在此范围内）为-2.4至3.1 mm Hg。遥测Neurovent-P-tel传感器系统在超出正常ICP值的广泛范围内具有良好的准确性，可能在临床实践中有用。
