研究设计:

横断面 

Study design:

Cross-sectional 

研究目的:

1.主要目的:监测失血患者的光电容积脉搏波(PPG)信号,融入深度机器学习算法,构建一套能实时反映失血患者状况的早期失血代偿储备评估模型。 2.次要目的:将所构建的失血代偿储备评估模型与传统评估模型进行对比,分析二者在预测失血患者预后方面的价值。  

Objectives of Study:

I. Primary Objective: To construct an early hemorrhagic compensatory reserve assessment model by monitoring photoplethysmography (PPG) signals in hemorrhagic patients and integrating deep learning algorithms, enabling real-time reflection of patient status. II. Secondary Objective: To compare the predictive value of the constructed hemorrhagic compensatory reserve assessment model versus conventional assessment models in forecasting clinical outcomes of hemorrhagic patients.
