title: [The role of gravitational tidal changes in regulating the systemic response of circulation and respiration to orthostasis].
abstract: The transient reply parameters of passive postural changes (lying-sitting) were evaluated. The most important 8 variables of circulation and respiration were analysed during 20-30 min of orthostatic test. The findings were based on 552 tests performed on 237 volunteers. It was shown that the adaptation of a human organism to the postural hydrostatic factor is formed by the systemic cooperation of circulation and respiration like a hydraulic homeostat. Influence of some physical factors (physiotherapy) changed this cooperation. The same data is discovered in orthostatic responses as a result of the different phases of lunar-semidiurnal gravity waves. That confirmed the gravity tidal variations have influence on human regulation systems.
