Respiratory and heart rate monitoring dataset from aeration study

A study was conducted to collect respiratory pressure and flow data for model-based assessment, alongside electrical impedance tomography (EIT) aeration, electrocardiogram (ECG), and heart-rate belt (HRB) data. A 20 subjects set was selected with no known significant respiratory abnormalities, under University of Canterbury Human Research Ethics Committee (HREC) consent (HREC 2023/30/LR-PS). Subject demographic data was collected using a combination of measurements and a self-reported questionnaire. Subject demographic information to ascertain: sex; height; weight; age; any history of asthma, smoking, or vaping; and approximate thoracic cage and breast tissue volumes. The trial was setup with subjects breathing through the pressure and flowmeter using a full-face mask and filter. Inspiratory and expiratory flow were separated using one-way valves for measurement purposes and both ports were rapidly occluded every 200ms to generate passive mechanics assessment intervals. A continuous positive airway pressure (CPAP) machine was used to provide positive airway pressure (PEEP) in series with the inspiratory port. Three trials were conducted per subject. Two of which, involved increasing PEEP (0, 4, and 8 cmH2O), and in one of which subjects were asked to perform two 10s breath holds at each level. The third was a recording of three forced expiratory manoeuvres (FEM). These tests were conducted to provide an initial comparison of current respiratory techniques to model-based methods, which aims to inform the design of future clinical testing on subjects with known respiratory abnormalities.

本研究旨在收集呼吸压力和流量数据以支持基于模型的评估，同时辅以电阻抗断层扫描（EIT）通气、心电图（ECG）以及心率带（HRB）数据。选取了20名无显著呼吸系统异常的受试者参与研究，并经坎特伯雷大学人类研究伦理委员会（HREC）批准同意（HREC 2023/30/LR-PS）。受试者人口统计学数据通过测量和自填问卷相结合的方式收集。收集受试者人口统计学信息以确定：性别；身高；体重；年龄；哮喘、吸烟或电子烟使用史；以及大致的胸腔和乳腺组织体积。试验中，受试者通过全脸罩和过滤器通过压力和流量计进行呼吸。采用单向阀将吸气流量和呼气流量分离，并每200毫秒快速封闭两个端口以生成被动力学评估间隔。使用持续气道正压（CPAP）机为吸气端口提供正压（PEEP）。每位受试者进行了三次试验。其中两次涉及增加PEEP（0、4和8 cmH2O），在另一次试验中，要求受试者在每个水平上进行两次各10秒的屏气。第三次试验记录了三次强制呼气操作（FEM）。这些测试旨在对当前的呼吸技术进行初步比较，并与基于模型的方法进行对比，以期为已知呼吸系统异常受试者的未来临床测试设计提供信息。
