Peripheral Blood Circulation

Methods of pulse oximetry and photoplethysmography are widely used in clinical medicine and practice of biomedical research outside the clinic. The advantages of the method are high efficiency of preparation for the diagnostic procedure, non-invasive, complete safety for health. The method provides the possibility of unlimited long - term monitoring of the dynamics of saturation and desaturation of hemoglobin. In combination with the above, subject to the qualitative registration of photoplethysmograms, the method allows the calculation and analysis of a number of indicators of peripheral blood circulation: the total pulse blood flow to the study region, the tone of arterial vessels of different diameters, the state of capillary blood flow. Most modern foreign models of pulse oximeters are integrated devices that provide measurement of a very limited set of physiological parameters: the percentage of hemoglobin oxygen saturation and pulse rate. The range of pulse oximeters containing the interface with the personal computer and providing operational calculation of indicators of peripheral photoplethysmograms is small. Such devices have a fairlyhigh cost and are not portable. The development of domestic integrated electronic devices is extremely relevant, allowing along with obtaining information about blood oxygenation to perform continuous monitoring of peripheral blood circulation. The authors developed an electronic module that provides long-term registration of photoplethysmograms in the infrared and red areas of the light spectrum. The electronic module is made exclusively with the use of domestic active radio elements – discrete semiconductor devices and integrated circuits. The device was developed in full compliance with the import substitution policy pursued by the President and the Government of the Russian Federation. The advantage of the device is the "open architecture" of the electronic circuit, which provides four analog signals suitable for further digitization. The signals contain information about pulsating and non-pulsating components of the optical density of biological tissue in the infrared and red ranges of the spectrum. The device has an electronic filter of mains interference. Tests of the device demonstrated high quality of photoplethysmograms. This makes it possible tosuccessfullyuse the device for studies of hemoglobin oxygenation and peripheral hemodynamics.

Pathological change experienced by patients with type 2 diabetes mellitus is impaired peripheralblood circulation, especially in the lower limbs and feet. Peripheral blood circulation can be examinedby measuring Ankle Brachial Index (ABI). Therapeutic exercise walking is one of physical activitieswhich can improve blood circulation. This research goal was to analyze the effect of therapeuticexercise walking on peripheral blood circulation in patients with type 2 diabetes mellitus. Theresearch design was randomized control group pretest-posttest design. The sample size was 15respondents as control group and 15 respondents as treatment group. Data was analyzed by usingdependent t-test and independent t-test with significant level of 0.05. This result showed a significantincrease of ABI after therapeutic exercise walking in the treatment group (p= 0.001). However therewas a significant decrease of ABI between pretest and posttest in control group (p=0.010).Independent t-test indicated a significant difference of ABI between treatment group and controlgroup (p=0.000). So, it can be concluded that there is an influence of therapeutic exercise walking onthe peripheral blood circulation in patients with type 2 diabetes mellitus. Nurses should applytherapeutic exercise walking to improve peripheral blood circulation in patients with type 2 diabetesmellitus.Keywords: type 2 diabetes mellitus, therapeutic exercise walking, ankle brachial index

AbstractElectrical signals from a photoelectric plethysmograph are used to test peripheral blood circulation as a source of a homoeopathically relevant parameter that will vary in a reproducible and systematic way following exhibition of specific medicines in homoeopathic doses. Mathematical treatment of the signals gives a Fourier power spectrum with an approximately linear profile (in a log-log plot) at the lowest frequencies. The gradient of this line seems to meet the above requirements of reproducible and systematic variation under a homoeopathic stimulus, and this is our basis to propose an analogous treatment for other electrical signals from the body, especially those from the heart and brain.
