Method and apparatus for isolating the vascular component in digital temerature monitoring
First Claim

1. A method for identifying and controlling neurovascular influence in endothelial function measurement in a patient, comprising:
- measuring skin temperatures on a test body part and a contralateral control body part simultaneously;
determining if the skin temperatures are above a set minimum temperature;
if the set minimum temperature is attained, automatically providing a vasostimulant to the subject to substantially cease blood flow to the test body part;
continuously monitoring the skin temperature changes of the test and control body parts during provision of the vasostimulant;
automatically removing the vasostimulant to allow blood flow to the body part;
comparing the skin temperatures to both the test and control body parts before, during and after removal of the vasostimulant; and
determining whether the measured temperature over time of the control body part is substantially stable.

Abstract
Methods and apparatus are provided for identifying and minimizing neurovascular contributions to determinations of endothelial function, including by digital temperature monitoring such that an accurate status of vascular reactivity can be obtained. Methods are also provided for identifying individuals having increased sympathetic nervous system activity impacting peripheral vascular function as well as for determining a status of diabetic foot.

18. A method for identifying a status of diabetic foot in a patient, comprising:
-
determining a measure of perfusion on both feet of a diabetic patient before during and after providing a vasostimulant to the patient;
comparing the measures of perfusion between the feet. - View Dependent Claims (19, 20)
