[Changes in the oxygen transport function in patients with chronic kidney failure during hemodialysis]

Some parameters of oxygen transport blood function have been studied prior to hemodialysis treatment and following 5, 25, 50 and 100 hemodialysis procedures. It has been established that programmed hemodialysis decreases O2 transport and reserve. These changes may be associated with an unfavourable effect of the procedure itself on the body, accompanied by anemia, microthromboembolisms in lung vessels, hypercapnia and arteriovenous blood shunt. Partial compensation of O2 transport decrease is achieved due to cardiac output increase and O2 tissue excretion. These compensatory mechanisms cannot ensure normal values of O2 reserve and transport and are fairly quickly depleted in the course of hemodialysis.
