Analysis of Ventilator Alarms Based on Machine Learning

中文摘要英文摘要

目的 探讨应用机器学习方法对呼吸机在临床使用中的通气类报警进行研究,获得影响报警的重要参数及报警预测模型,识别无效报警并给予临床提示,使临床得以高效应对呼吸机报警,避免造成报警疲劳等消极影响.方法 建立符合标准数据流程的呼吸机数据管理平台,根据单中心的呼吸机报警信息分析特征值,得出重要参数排序;利用超参数调优建模预测报警的真假;用混淆矩阵、受试者工作特征(Receiver Operating Characteristic,ROC)对机器学习模型进行多项指标验证.结果 对测试集5936次通气类报警进行评估,得出无效报警率为88%(召回率为0.88),模型准确度为0.94,精准度为0.78,ROC曲线下面积为0.92,F1得分为0.82.结论 采用机器学习便于临床单中心数据建模,能够及时分析获得呼吸机真实警报的重要参数及报警预测;通过呼吸机数据管理平台可有效提示临床无效报警,从而减少医护人员的压力,提高医疗质量.

Objective To study the ventilation alarms of ventilators in clinical use by applying machine learning methods,obtain the important parameters affecting the alarms and the alarm prediction model,identify invalid alarms and give clinical hints,so that the clinic can respond to the ventilator alarms efficiently to avoid the negative effects of alarm fatigue and other negative impacts.Methods A respiratory data management platform was established that conformed to standard data processes.According to the alarm information of single center ventilator,the characteristic values were analyzed and the important parameters were sorted.Hyperparameter optimization modeling was used to predict the true or false alarm.The confusion matrix and receiver operating characteristic(ROC)were used to validate the machine learning model.Results The test set of 5936 ventilation alarms was evaluated,with 88%invalid alarms rate(recall rate was 0.88).The model accuracy was 0.94,and the precision was 0.78,the area under ROC curve was 0.92.The F1 score was 0.82.Conclusion The use of machine learning facilitates clinical single-center data modeling can timely analyze and obtain the important parameters and alarm predictions of the real alarm of the ventilator,and through the ventilator data management platform,it can effectively prompt the clinical invalid alarms,thus reducing the pressure of the alarms on the healthcare personnel and improving the quality of medical care.
