“…Such a difference in the growth rate of blood filling in different groups of patients was as a result of vasodilatation associated with the release of histamine, which was excreted in the degradation of mast cells and expanded the clearance of arterioles, capillaries, venules, and also accelerated capillary blood filling. So, patients who had increased body weight, a direct proportional increasing of the blood filling in the areas of postoperative wounds was observed [1,4].…”

Introduction. The human health directly depends on the state of peripheral blood circulation. Blood filling disturbance causes various types of disorders of our body. For example it causes the bad healing of postoperative wounds. Therefore, for timely and qualitative diagnosis of such disorders the modern medicine uses non-invasive methods; these methods allows painless and non-destructive control of affected areas. The most perspective among them are optical methods for recording and transforming of biomedical information [1, 2, 5]. Obesity is one of the actual problems of modern world medicine, and it's one of the reasons of the bad healing of postoperative wounds. It is caused by the difference in the blood filling of tissues in patients with different body mass. Method and results. An analysis of the blood filling of the anterior abdominal wall was provided on the basis of the VNMU Department of General Surgery and of the Surgical Department of the Сlinical hospital №1 in the city of Vinnytsia. Determination of the blood filling was carried out by means of opto-electronic plethysmograph, which was developed by us. Were examined patients with inguinal groin hernias (20 men and 20 women) with different body mass, aged 27-75 years. All patients were divided by body mass index (BMI) and by the degree of obesity into 4 groups. The 1 st (control) group included 15 patients with normal body weight (BMI 18.5-24.9). The 2 nd group included 9 patients with overweight and the I degree of obese (BMI 25.0-29.9 and 30.0-34.9 respectively). The 3 rd group included 10 patients with II degree of obese (BMI was 35.0-39.9). The 4 th group included 6 patients with obesity of the III and IV degrees (BMI≥40.0). At that time, starting from the 2 nd day after surgery treatment was performed stimulation of microcirculation in the area of the postoperative wound for patients with obesity of the III and IV degrees. And was measured the blood filling in the tissues of the postoperative wound area before and after surgery. There were 32 patients (18 men and 14 women) aged 28 to 60 years old

“…Zlepko et al evaluated vessels’ tone and characteristics of the local blood flow using a photoplethysmographic device. The primary investigation areas were fingers, toes, the prebrachial joint, and the middle third part of the tibia [ 17 ]. Tusman et al attempted to detect changes in systolic arterial blood pressure (SAP) and vascular tone using a classification based on the contour of the photoplethysmography signal (PPGc).…”

Vascular tone plays a vital role in regulating blood pressure and coronary circulation, and it determines the peripheral vascular resistance. Vascular tone is dually regulated by the perivascular nerves and the cells in the inside lining of blood vessels (endothelial cells). Only a few methods for measuring vascular tone are available. Because of this, determining vascular tone in different arteries of the human body and monitoring tone changes is a vital challenge. This work presents an approach for determining vascular tone in human extremities based on multi-channel bioimpedance measurements. Detailed steps for processing the bioimpedance signals and extracting the main parameters from them have been presented. A graphical interface has been designed and implemented to display the vascular tone type in all channels with the phase of breathing during each cardiac cycle. This study is a key step towards understanding the way vascular tone changes in the extremities and how the nervous system regulates these changes. Future studies based on records of healthy and diseased people will contribute to increasing the possibility of early diagnosis of cardiovascular diseases.
