Abstract
The complex periodic form of respiration was investigated; it has a reflectorial nature and appears to be the result of deep change in physiological functions during the disruption of the form and intensity of afferent information with sinocarotid receptive zone. Complex periodic respiration and Traube-Gehring waves become intensified during the crosscut of straying nerves; this is also connected with the disruption in intensity of afferent information. At high altitude, complex periodic respiration and TraubeGehring waves originate much faster than in ordinary living conditions of the organism. With excess intrapulmonary pressure of up to 200-400 mm water col., the oxygen tension in the brain tissues of dogs rise considerably. When a much higher degree of excess pressure is created in the lungs, up to 600-800 and 1200 mm water col. without counterpressure against the body, the oxygen tension in the brain tissues rises slightly or remains without changes. Under excess pressure of 300-400 mm water col., at an elevation of 15000 m for a period of 10 min without the use of counter pressure against the body, the oxygen tension in the cortex cerebi of dogs is preserved up to 62-84%, and in the crust up to 49-74% of the initial.
