Abstract
A body fluid component and/or temperature monitoring system including a fiber optic catheter, fluid monitoring probe at the distal end of the catheter, pulsed light source for exciting the probe, and photosensor for responding to light coming from the distal end of the catheter. Circuitry analyzes the light output from the probe and determines a time delay that characterizes the body fluid component concentration or temperature. The time decay is then preferably converted to either component concentration or temperature and displayed on a visual display.
