ABSTRACT
A study was made of the characteristics of respiration recorded during the use of a respirator for preparing hypoxic hypercapnic mixtures as compared to the use of an additional "dead" space. In both cases, there was a significant increase of total ventilation, largely at the expense of respiration deepening. However, during respiration via a respiratory mask, the increase of the minute respiratory volume was accompanied by a rise of alveolar ventilation whereas during respiration via the ADS, alveolar ventilation dropped. Hyperventilation did not entail CO2 washing out from the blood and hypocapnia development during respiration via the mask and ADS. The differences revealed may appear helpful for respiration training at the hospital. In this case, an appropriate outfit should be sorted out for each patient on an individual basis.

Oxygen metabolism of a tube graft formed from the greater curvature of the stomach in esophagoplasty for carcinoma of the thoracic esophagus was studied by polarography. The study was conducted during the stages of treatment: in the early postoperative period and before the formation of a postponed extracavitary esophagogastric anastomosis. Oxygen tension (pO2) and the rate of oxygen consumption (ROC) by the graft tissue were studied. The pO2 for the isoperistaltic grafts was 65.3 +/- 2.31 mm Hg in the zone of the nutrient vessel and 51.68 +/- 11.6 mm Hg in the zone of the mechanical suture. A favourable postoperative period corresponded with a ROC of 0.1-0.2 units. The results of the study coincided with the clinical result in 86.3% of cases.

Effect of magnetophore applicators constant magnetic field (MACMF) on the functional state of human skin at reparative and destructive processes. It has been found in the investigations carried out during epidermatoplasty under the magnetic field effect on the reparation zone for 10--12 days that MACMF effect is of antihypoxic character and is manifested locally and only on a regenerating tissue. In the experiments on skin grafts exposed to magnetic field for 22--26 hours there was also found antihypoxic direction of MACMF effect expressed in the stabilization of tissue respiration, which points to the weakening of destruction.
