星形图在下体负压试验医监中的应用

Star Figure in Medical Monitoring during Lower Body Negative Pressure Test.

目的探讨在下体负压试验中，实时、快速、直观地评价被试者的生理机能状态和可能发展趋势的方法。方法采用星形图技术，将多个生理指标在下体负压作用时的变化趋势在同一平面坐标上以特殊的几何图形表示出来，根据星形图的特点和其稳定性判断出被试者的生理功能状态是否稳定。结果形成了个体的应激反应模式，使用指标星形图较准确地对机体的功能状态进行了评价。结论根据星形图图形变化的特点可以对被试者生理功能状态可能发展的方向起到提示的作用。

Objective To find a real-time, quick and audio-visual method to evaluate the subject's physiological function condition and possible development. Method Star figure technique was adopted to analyse multiple physiological indices during lower body negative pressure test(LBNP).Based on the character and stability of the stars figure,the steadiness of the subjects physiological function can be judged. Result Physiological function can be accurately assessed only when the model of stress response of an individual is formed. Conclusion The changes of star figure can indicate the possible development of the physiological function stage.
