Visualization of how reactions were calculated during bolus infusions (Top) and constant pressure infusions (Bottom). Individual pressure steps used for the constant pressure infusions Horizontal lines illustrate example upper and lower limits of pressure waveforms. All amplitudes are peak-to-peak. Please note that the timeframe represents elapsed time. ICPamp, intracranial pressure pulse amplitude; ITPamp, intrathecal pressure pulse amplitude; ABPamp, arterial blood pressure pulse amplitude; CVPamp, central venous pressure pulse amplitude
