20080214943 | Detection of Blood Flow Using Emitted Light Absorption - Perfused tissue is illuminated and light passing through the tissue or reflected from it is detected to produce an electrical signal. Amplitude pulses corresponding to the subject's heart beat are detected in the electrical signal and the areas of these pulses are calculated to produce blood flow values indicative of the blood volume pumped by the heart. The blood flow values may be used alone or in combination with other measured cardiac parameters to evaluate cardiac function. | 09-04-2008 |
