A-F shows simultaneous recordings from one female subject. From top: water bath temperature (°C), blood velocity in finger artery (m/s), blood velocity in radial artery of the control hand (m/s), blood pressure (systolic, mean arterial, and diastolic pressure in mmHg), heart rate (beats/min) and core temperature (°C). Change in water bath temperature between two broken lines (at 5-15 min).

Figure 2: From top, the plot A-D displays average core temperature (°C) for all 11 subjects, average blood velocities (m/s) in finger artery and control artery for 9 subjects. At the bottom the 2 and 98% percentiles and average blood velocity from both arteries (9 subjects) were normalized and plotted in a ±45-seconds sliding window and plotted together in the same panel for comparison. The raise in water bath temperature occurs between dotted lines (at 5-15 minutes).
