Article Title: Continuous Intracranial Pressure Monitoring in Children with ‘Benign’ External Hydrocephalus
doi: 10.3390/jcm14093042
Figure Lengend Snippet: Continuous intracranial pressure (ICP) was recorded using an epidural sensor (Neurodur-P, Raumedic, Rehau AG + Co, Rehau, Germany), along with PowerLab 4SP hardware and LabChart 8.1 software for analysis. In the ( top ) section, the raw ICP signal is displayed, sampled at 200 Hz (in red). The ( bottom ) section shows the same ICP signal as the upper channel but visualized through a smoothing triangular Bartlett digital filter, implemented in LabChart software, which generated a time-domain smoothed signal (in blue). Note how the B waves (green dashed lines) are much clearer in the bottom ICP recording.
Article Snippet: All other patients were monitored utilizing a custom-designed digital recording technology platform based on the ADInstruments PowerLab 4SP hardware and LabChart v8.1 software (ADInstruments, Ltd., Grove House, Hastings, UK) with the ICP signal sampled at 200 Hz, well above the minimum rate at which digital sampling can accurately record an analog signal (Nyquist Frequency) [ ].
