研究目的: |
主要目的:系统评估并对比各单一多模态指标(包括 EIT、超声指标、CPF、HRV 及传统临床指标)对机械通气患者撤机失败的预测性能,明确其诊断价值。 次要目的: 预测方法探索:尝试性构建简约临床模型与 AI 模型,初步比较不同建模方法的潜力。 多元关系挖掘:通过相关性分析、亚组分析等方法,探讨指标间的内在关联与临床背景下的表现差异。 数据驱动发现:利用无监督聚类初步探索撤机失败的潜在生理表型。 |

Objectives of Study: |
Primary Objective: To systematically evaluate and compare the predictive performance of individual multimodal parameters — including electrical impedance tomography (EIT), ultrasound?based indices, cough peak flow (CPF), heart rate variability (HRV), and traditional clinical variables — for weaning failure in mechanically ventilated patients, and to clarify their diagnostic value. Secondary Objectives: Prediction methodology exploration – To preliminarily construct a parsimonious clinical model and an artificial intelligence (AI) model and to compare the potential of different modelling approaches. Multivariate relationship discovery – To investigate internal correlations among parameters and performance differences across clinical contexts using correlation analysis, subgroup analysis, and related methods. Data?driven phenotyping – To preliminarily explore potential physiological phenotypes of weaning failure using unsupervised clustering. |
