  • To explore the impact of pressure on human body's blood circulation and its variation by studying the variation of pilots' physiological parameters in their capstan partial pressure suits with the method of simulation, which can provide theoretical support for pilots' safety. According to the characteristics of the partial pressure suits, a hemodynamic model under pressure was established on the basis of Heldt orthostatic stress model. At the same time the correctness of the model were verified through the ground pressure experiments. The model can simulate the hemodynamic parameter of systemic side-tube partial pressure suit under pressure, concluding heart rate, mean arterial pressure, stroke volume and cardiac output. Then the simulative and experimental data in the parameter of mean arterial pressure, stroke volume and cardiac output were compared. The results agree well with the experimental results, and verify the validity of model. This model can effectively simulate the hemodynamic changes of partial pressure suits under pressure.
