Abstract

L'invention concerne un procédé de mesure de la masse d'hémoglobine vasculaire totale. Une étape de ce procédé consiste à mettre en mémoire un volume de fluide à injecter au moyen d'un processeur. Une valeur d'hémoglobine est mesurée in vivo sur une base sensiblement continue. Le procédé mesure également un volume vasculaire en circulation total basé sur le volume de fluide à injecter par détection d'un changement de la concentration sanguine pendant une certaine période de temps lors de l'injection d'un fluide à l'intérieur d'un corps. La masse d'hémoglobine totale est calculée sur la base de la valeur d'hémoglobine mesurée et du volume vasculaire en circulation total.
