What is the second temperature probe used for?
A17. The second probe monitors fingertip temperature changes on the contralateral, non-occluded hand. Temperature data from the second probe were originally intended to serve as a relatively stable, reference curve. However, recent studies have revealed that temperature changes in the non-occluded hand may provide additional insight into the subject’s vascular function. It is hypothesized that increased fingertip temperature in the contralateral hand is a physiologic, neurally-mediated, systemic response to the ischemic stimulus. It is further hypothesized that this response would be vasodilatory in healthy individuals and hampered in individuals with cardiovascular risk factors and sympathetic overactivity.
