Measure time point of outcome:

On the first, third, and seventh day after joining the group

Measure method:

Record the laboratory results of patients on the first, third, and seventh day after enrollment, including validation indicators, blood gas indicators, and biomarkers.

指标中文名:

患者第三日较第一日全局不均一指数(GI)的变化。(全局不均一指数(GI)指数表示患者呼吸分布的空间范围和分散程度,即通气的整体空间异质性程度。)

指标类型:

主要指标

Outcome:

The change in global heterogeneity index (GI) of the patient on the third day compared to the first day.

Type:

Primary indicator

测量时间点:

入组后第一天、第三天

测量方法:

EIT绑带放置在患者胸部第五或第六肋间隙处,并连接到EIT设备PulmoVista 500。记录均匀的呼吸周期曲线变化后,将记录结果以离线软件EITEvaluationSDMI来计算不同吸气流速状态下肺通气均一程度,评估指标为GI。

Measure time point of outcome:

On the first and third day after joining the group

Measure method:

The EIT strap is placed at the fifth or sixth intercostal space of the patient's chest and connected to the EIT device PulmoVista 500. After recording the uniform changes in the respiratory cycle curve, the recorded results were used to calculate the degree of lung ventilation uniformity under different inspiratory flow rates using the offline software EITEvaluation DMI, with the evaluation index being GI.
