研究目的: |
通过经典公式计算方法、床旁EIT及DECT三种工具,系统地描述ICU内AHRF患者肺部通气与灌注的特点; 定量分析ICU内AHRF患者的多种肺部病变的通气-血流匹配受损程度; 探讨由经典公式计算方法、床旁EIT及DECT三种工具获取的通气和灌注分布数据及图像,在ICU临床的应用价值。 |

Objectives of Study: |
To systematically characterize lung ventilation and perfusion in patients with AHRF in the ICU by using three tools: classical formula calculation method, bedside EIT and DECT; To quantify the degree of impaired ventilation-perfusion matching for multiple lung lesions in patients with AHRF in the ICU; To explore the value of the ventilation and perfusion distribution data and images obtained by the classical formula calculation method, bedside EIT and the three tools of DECT, for clinical application in the ICU. |

盲法: |
为降低可能出现的临床试验研究人员的主观偏差和个人经验对试验结果的影响,本次试验采用盲法设计。负责筛选的临床研究者与负责样本检测者、EIT和DECT实施者分别为不同人员,即检测者、操作者对相关的患者信息处于盲态。严格按照试剂说明书以及EIT和DECT操作、软件分析的要求进行,研究过程中得到的结果,由另一研究人员协助如实报告数据,最后由另一临床研究者进行数据录入汇总。研究过程中不能相互透露与本项目相关的任何信息。 |
|
Blinding: |
To reduce the possible influence of subjective biases and personal experience of clinical trial researchers on the trial results, a blinded design was adopted in this trial. The clinical researchers responsible for screening and the sample testers, EIT and DECT implementers are different personnel, that is, the testers and operators are blind to the relevant patient information. The research was conducted strictly in accordance with the reagent instructions as well as the requirements for EIT and DECT operations and software analysis. The results obtained during the research process were reported truthfully with the assistance of another researcher, and finally the data was entered and summarized by another clinical researcher. During the research process, no information related to this project should be disclosed to each other. |
