Figure 5

Relationship between minimum evoked current (MEC) + rate of change in K for 80 mA tetanus stimulation (KR80) and rate of change of systolic blood pressure (ROCBP). A scatter plot of each minimum evoked current (MEC), vascular stiffness value (K), systolic blood pressure (sBP), heart rate (HR), photoplethysmography amplitude (PPG), and rate of change of systolic blood pressure (ROCBP) is shown. Out-of-range cases are shown using green points, and Smirnoff-Grubbs test outlier points are shown in red. A downward rightward trend is observed for MECK, MECBP, and MECPPG, and an upward rightward trend is observed for KR80.
