本文应用相关及多元逐步回归方法探讨RSTI 与肺循环血流动力学多项指标的关系,以期更客观的评价各因素的综合作用,探求用 RSTI 反映肺循环血流动力学变化。
In this paper, we use correlation and multiple stepwise regression methods to explore the relationship between RSTI and multiple indicators of pulmonary hemodynamics in order to more objective evaluation of the combined effect of various factors to explore the use of RSTI to reflect changes in pulmonary hemodynamics.
