[Characteristics of hypoxia development in aged people].
The aim of the study was to investigate the peculiarities of tissue oxygen provision on the level of microcirculatory bed and to determine the significance of the indices taken separatively in pathogenesis of hypoxia in practically healthy elderly people. The study comprised 30 practically healthy people aged 60-74. It included investigation of oxygen tension in peripheral tissues, skin and bulbar microcirculation, functional state of endothelium in the group of elderly healthy people. The results obtained were compared with analogous data obtained in practically healthy young subjects. The tissue oxygen provision was found to decrease with age.
