Abstract

The method consists of continuous definition of the concentration of haemoglobin (HgB) on the basis of the absorption of a luminous radiation, which goes through blood flowing in a transparent tube (6). The method furthermore consents a calculation of the percentage of variation in the haematic volume (DVE%) respect to a basal concentration (Hgb0). The apparatus includes an optoelectronic probe (5) of the radiation and a control circuit (47) that alternates readings (SE) from the probe (5) with electronic test readings (SE'). The readings (SE) are analyzed to check reliability and are transformed into concentration of haemoglobin by a specific transferring characteristic. A display (48) continuously shoes the results of the reliability check test and the data on concentration and percentage of variation. Figure 3<IMAGE>
