研究目的: |
1、建立标准化评估工具:实现气道解剖储备精准、便捷量化,完成信度(评分者间一致性ICC≥0.8)、效度(以FEV1% pred为金标准)验证,通过第三方质控保障多中心评估结果同质化、客观可信。 2、量化动态生理韧性:挖掘麻醉诱导期动态生理韧性核心特征,识别低氧血症及紧急退镜发生前180秒的生理损耗特征,阐明波形异变与循环生理的关联规律,锁定可提前3~5分钟预警的最优特征组合。 3、构建高精度预测模型:构建并验证“解剖-炎症-生理”多模态退镜风险预警模型,实现跨中心、跨麻醉方案精准预测(外部验证AUC≥0.75),明确核心风险驱动因素,评估临床应用价值,形成标准化预警实施方案。 |

Objectives of Study: |
1. Establish a standardized assessment tool: Achieve precise and convenient quantification of airway anatomy reserves. Validate reliability (inter-rater consistency ICC ≥ 0.8) and validity (using FEV1% pred as the gold standard). Ensure homogenized and objectively credible multi-center assessment results through third-party quality control. 2. Quantify dynamic physiological resilience: Identify core features of dynamic physiological resilience during the anesthesia induction period. Characterize the physiological depletion patterns occurring 180 seconds before the onset of hypoxemia and emergency withdrawal. Elucidate the association between waveform aberrations and circulatory physiology. Determine the optimal feature combination that can provide early warning 3–5 minutes in advance. 3. Develop a high-precision predictive model: Construct and validate a multimodal (anatomy-inflammation-physiology) early warning model for withdrawal risk. Achieve accurate predictions across different centers and anesthesia protocols (external validation AUC ≥ 0.75). Identify core risk-driving factors. Evaluate the model's clinical application value and establish a standardized protocol for early warning implementation. |
