Abstract
This paper describes the design and construction of an organ blood-flow meter which uses an indwelling venous fiber optic catheter and an infrared absorbing indocyanine dye. The instrumentation design consisted of: a light source, fiber bundles, couplers, a photodiode sensor, an electronic filter, and an analog-to-digital conversion circuit. Static tests were done to demonstrate a technique sensitivity for detection of the dye in concentrations as low as 3.1 mg per liter of blood.
