基于证据回归的血压连续监测

Continuous Monitoring of Blood Pressure with Evidential Regression

Hyeongju Kim, Woo Hyun Kang, Hyeonseung Lee, Nam Soo Kim

摘要:

基于光电容积描记图(PPG)信号的血压(BP)估计是现代BP测量的有希望的候选者,因为PPG信号可以以非侵入性方式容易地从可穿戴设备获得,从而允许快速BP测量。然而,现有的基于机器学习的BP测量方法的性能仍然落后于一些BP测量指南,并且其中大多数仅提供收缩压(SBP)和舒张压(DBP)的点估计。在本文中,我们提出了一种尖端的方法,能够从PPG信号中连续监测BP,并满足医疗器械促进协会(AAMI)和英国高血压协会(BHS)标准等医疗标准。此外,所提出的方法通过估计其不确定性来提供预测BP的可靠性,以帮助基于模型预测的医疗状况的诊断。MIMIC II数据库上的实验验证了所提出的方法在几个指标下的最新性能,并能够准确地表示预测中的不确定性。

英文摘要:

Photoplethysmogram (PPG) signal-based blood pressure (BP) estimation is a promising candidate for modern BP measurements, as PPG signals can be easily obtained from wearable devices in a non-invasive manner, allowing quick BP measurement. However, the performance of existing machine learning-based BP measuring methods still fall behind some BP measurement guidelines and most of them provide only point estimates of systolic blood pressure (SBP) and diastolic blood pressure (DBP). In this paper, we present a cutting-edge method which is capable of continuously monitoring BP from the PPG signal and satisfies healthcare criteria such as the Association for the Advancement of Medical Instrumentation (AAMI) and the British Hypertension Society (BHS) standards. Furthermore, the proposed method provides the reliability of the predicted BP by estimating its uncertainty to help diagnose medical condition based on the model prediction. Experiments on the MIMIC II database verify the state-of-the-art performance of the proposed method under several metrics and its ability to accurately represent uncertainty in prediction.
