METHOD OF MEASURING TOTAL VASCULAR HEMOGLOBIN MASS

摘要

A method of measuring total vascular hemoglobin mass. One step of the method is to store a volume of fluid to be injected using a processor. A hemoglobin value is measured in vivo on a substantially continuous basis. The method also measures a total circulating vascular volume based on the volume of fluid to be injected by detecting a change in blood concentration over a period of time upon injection of a fluid into a body. The total hemoglobin mass is calculated based on the measured hemoglobin value and the measured total circulating vascular volume.

1. A method of measuring total vascular hemoglobin mass, the method comprising the steps of:
storing a volume of fluid to be injected using a processor; measuring a hemoglobin value in vivo on a substantially continuous basis; measuring a total circulating vascular volume based on the volume of fluid to be injected by detecting a change in blood concentration over a period of time upon injection of a fluid into a body; calculating a total hemoglobin mass based on the measured hemoglobin value and the measured total circulating vascular volume using the following formula:THM=Hgb(gdL)*BV(dL) where THM is total hemoglobin mass in grams, Hgb is the measured hemoglobin value in grams per deciliter, and BV is the measured total circulating vascular volume in deciliters; and displaying the total hemoglobin mass.
