In patients requiring ICP monitoring, a ventricular catheter connected to an external strain gauge transducer or catheter-tip pressure transducer device is the most accurate and reliable method of monitoring ICP, and enables therapeutic CSF drainage. Clinically significant infections or hemorrhage associated with ICP devices causing patient morbidity are rare and should not deter the decision to monitor ICP. Parenchymal catheter-tip pressure transducer devices measure ICP, similar to ventricular ICP pressure, but have the potential for significant measurement differences and drift due to the inability to recalibrate. These devices are advantageous when ventricular ICP is not obtained or if there is obstruction in the fluid coupling. Subarachnoid or subdural fluid-coupled devices and epidural ICP devices are currently less accurate.
在需要进行颅内压（ICP）监测的患者中，连接到外部应变片传感器或导管尖端压力传感器装置的脑室导管是监测ICP最准确、最可靠的方法，并且能够进行治疗性脑脊液引流。与ICP装置相关的具有临床意义的感染或出血导致患者发病的情况很少见，不应妨碍做出监测ICP的决定。实质内导管尖端压力传感器装置测量ICP的方式与脑室ICP压力类似，但由于无法重新校准，存在显著测量差异和漂移的可能性。当无法获得脑室ICP或在液体耦合中有梗阻时，这些装置具有优势。蛛网膜下腔或硬膜下液体耦合装置以及硬膜外ICP装置目前准确性较低。
