Finger 300: finger temperature at the onset of cuff occlusion (time 300 s); VRI: vascular reactivity index; NVRI: neurovascular reactivity index; Cold Finger: a flagged condition in which right finger 300 is equal to or less than 27°C; Sympathetic Response: a flagged condition in which left finger temperature continuously declines after right arm-cuff occlusion.
