N2 - In the periopperative area, the period befoore and after surgery, it is essential to measure ddiagnostic paraameters such as oxygennsaturation, hhemoglobin (HHb) concentratiion and pulse. The Hbbconcentratio n in human bblood is an impportant parameter to evaluate the physiological condition. Byydetermining the Hbbconcentrationn it is possible to observe immminent postoperative bleeding anddautologous retransfusionss. Currently, invasivve methods are used to meaasure the Hb cconcentration. For this purpose blood is takennand analyzeed. The disadvantage of this methood is the delayybetween theeblood collection anddits analysis, which doesn' t permit a reeal-time patient monittoring in criticcal situations.A non-invasiive method allows paain free online patient monittoring with miinimum risk of infectiion and facilit ates real timeedata monitorring allowing immeddiate clinical reeaction to the mmeasured data.
