Abstract:
1. A system for determining non-invasively at least one cardiovascular parameter of a patient undergoing hemodialysis comprising: a) a dialyzer configured to perform hemodialysis on the patient, wherein the hemodialysis comprises blood removal from and administration of a fluorescent dye to the cardiovascular system of the patient; b) a probe assembly comprising: c) a processor configured to receive the sent electronic signal and to estimate at least one cardiovascular parameter of the patient based on the sent electronic signal; wherein the processor is configured to correct the estimation of the at least one cardiovascular parameter for changes in the blood hematocrit or hemoglobin content of the patient undergoing hemodialysis; and d) a monitoring system configured to monitor the estimated cardiovascular parameter during hemodialysis.
