Stimulation TcPO2 Test in the PAD Diagnosis in Diabetic Foot

"During measurement of TcPO2 in various angiosomes the stimulation test will be performed. We modify the Ratschow test (elevation of the lower limbs, rhythmic flexion and extension in talocrural joints for 2 minutes, then return to horizontal position). TcPO2 is measured continuously. Depending on the type of detected flows by DUS in the evaluated arteries supplying the relevant angiosome, in which TcPO2 values are measured, the patients and their angiosomes will be divided into 2 baseline groups - group M with monophasic flows or arterial obliterations and group T with triphasic flows.~We will compare macrocirculation parameters-systolic pressure on dorsalis pedis artery (DPA), posterior tibial artery (PTA) and their doppler indexes. The resting TcPO2, the minimal TcPO2 found during the stimulation test, their delta (resting TcPO2 - minimal TcPO2) and the percentage decrease in TcPO2 will be compared between the study groups, as well as the duration of TcPO2 recovery."
