The evaluation of the microcirculatory bed functional state and the identification of angiospastic disorders with related complications,when the pathological changes are reversible,have an important role in medical *** aim of this study was to evaluate the possibility of using optical noninvasive methods and the cold pressor test to solve this problem.A total of 33 patients with rheumatological diseases and 32 healthy volunteers were included in the *** Doppler flowmetry,tissue reflectance oximetry and pulse oximetry were used as optical noninvasive *** parameters were recorded before,immediately after and 20 min after the cold pressor *** on the measured parameters,the complex parameters of the microcirculatory bed were calculated.A detailed statistical analysis of the parameter changes for each individual in the two groups displayed diverse microcirculatory bed parameter responses upon cold exposure,with differing recovery of parameters after *** diagnostic criteria were proposed for the identification of angiospastic *** to the proposed criteria,27 people of the volunteers group were confirmed to not display any *** the patient group,however,18 people were observed to have a relatively normal functional state of the microcirculatory bed,while 15 people were observed to have a possible tendency to *** highlight the diferences between a relatively normal state and presence of angiospastic disorders,statistical analysis of experimental data was carried out,which revealed significant *** analysis of data with angiospastic disorders identified a relationship between their diagnoses and the results of labo-ratory ***,the evaluation of combined noninvasive optical diagnostic method use,the cold pressor test and proposed diagnostic criteria showed a positive *** approach can be used to detect the presence of possible angiospastic disorders and related complications,as
