WebTo investigate the relationships between long-term computer-assisted monitoring of intracranial pressure (ICP) and indices derived from its waveform versus outcome, age, and sex. Materials and methods: ICP and arterial blood pressure (ABP) were recorded directly and stored in bedside computers. WebIn order to better understand this technology, it is important to note that mean ICP is a time-average of the ICP waveform. The ICP waveform consists of three components: respiratory waveforms (0.1‒0.3 Hz) associated with the respiratory cycle, pulse pressure waveforms of frequency equal to the heart rate and slow vasogenic waveforms (e.g. …
