<p>A device (10) for determining perfusion capacity in a region of a patient's skin and underlying tissue includes a thermoelectric device (20) to create a temperature differential, a sensor (32, 34) for measuring the temperature differential, and a controller (108) coupled to the sensor (32, 34) and the thermoelectric device (20) for maintaining the temperature differential substantially constant by providing electrical energy to the thermoelectric device (20). The electrical energy provided to the thermoelectric device (20) when the thermoelectric device (20) is positioned adjacent the region of the patient's skin is indicative of the perfusion capacity.</p> |
