Heart and blood circulation system function evaluation device

摘要

The function evaluation device uses non-invasive optical and/or electrical measurement of physical parameters related to the heart operation, with auto-and/or cross-correlation of the measured values to provide functions which are stored and compared with normal values and/or characteristic curves. A dual wavelength NIR-ROT remission photoplethymographic measurement of the blood oxygen content can be obtained for each heart cycle, together with the relative microvascular filling volume, with storage of the functions obtained by auto-, or cross- correlation.
