Abstract
A system and method for measuring total circulating blood volume and cardiac output employing an analyte diffusion approach. The analyte sensor as well as the analyte-containing fluid infusion procedure may be carried out with instruments which are inserted in the bloodstream at peripheral locations of the body spaced from the heart. A controller is provided to automatically carry out these measurements as well as to provide threshold comparisons for alerting the practitioner to excursion in the parameters. The preferred analyte containing fluid is an ammoniacal fluid and the preferred sensed components is ammonia gas.
