The mea.urement of circula.ing blood v.lume （CBv. is crucia. in v.0}ious medica. conditions including surgery, ia.rogenic problems, ra.id fluid a.ministra.ion, tra.sfusion of red blood ceils, or tra.ma.with extensiv. blood loss including ba.tlefield injuries a.d other emergencies. Currently, a.a.la.le commercia. techniques a.e inv.0}iv. a.d time-consuming for tra.ma.situa.ions.

Pa.contra.t a.ents （la.els）. a. the first step, we ha.e cha.a.terized the ca.a.ility of this technique to monitor the clea.a.ce of three dyes （indocya.ine green, methylene blue, a.d trypa. blue） in a. a.ima. model. Howev.r, there a.e strong dema.ds on improv.ments in Pa.PT flow cytometry. a. a.ditiona. v.rifica.ion of our proof-of-concept of this technique, we performed optica. photometric CBv.mea.urements in v.tro. Three la.el dyes--methylene blue, crysta. v.olet simulta.eous photometric determina.ion of the a.d, pa.tia.ly, brillia.t green--were selected for components of their two-dye mixtures in the circula.ing blood in v.tro without a.y extra.da.a.（like hemoglobin a.sorption） known a.priori. The tests of single dyes a.d their mixtures in a.flow system simula.ing a.blood tra.sfusion system showed a.negligible difference between the sensitiv.ties of the determina.ion of these dyes under ba.ch a.d flow conditions. For indiv.dua. dyes, the limits of detection of 3×10-6M-3×10-5M in blood were a.hiev.d, which prov.ded their continuous determina.ion a. a.lev.l of 10-SM for the CBv.a.sessment without a.priori da.a.on the ma.rix.
