Fig. 2.

Standardized supine-stand test for the participants without orthostatic hypotension (OH) in the laboratory (A, B, C) and at home (D, E), showing responses of A blood pressure (BP), systolic in red (solid line), diastolic in blue (dashed line), and heart rate (HR) in green (dashed-dotted line). B + D Cerebral oxygenation measured with long channels, oxygenated hemoglobin in red, and deoxygenated hemoglobin in blue (dashed line) and C + E cerebral oxygenation measured with short channels, oxygenated hemoglobin in red, and deoxygenated hemoglobin in blue (dashed line). All signals are shown from 1 min before standing up to 170 s after standing up. These are averaged over all repetitions and subjects without OH (laboratory measurements) or all repetitions, measurement days, and subjects without OH. Standing up is indicated by a vertical black dashed line. Shaded areas show standard deviations for all signals
