A dataset of clinically recorded radar vital signs with synchronised reference sensor signals

In a previous publication the database of our phase 0 study on the feasibility of non-contact vital signs monitoring was published. Based on the data it has been shown that besides pulse and respiration, radar systems are also capable to measure the heart sounds of the test persons. The heart sound offers a significant advantage when trying to measure the heartbeat as precisely as possible, as it has a very concise and sharp morphology. This precision is, e.g., very important for determining the parameters of heart rate variability.<br>Following a successful phase 0, a clinical evaluation of the radar has been planned and performed. In phase 1, 30 healthy subjects were measured with the radar and a synchronised reference device, the so-called Task Force Monitor. In addition to non-contact continuous blood pressure, the Task Force Monitor can measure ECG, ICG and impedance. It also evaluates the raw signals and determines additional values such as heart rate, stroke volume, cardiac output, thoracic fluid content, total peripheral resistance, and many more.<br>Besides a resting scenario, scenarios such as the Valsalva maneuver, tilt table test or breath holding were performed to evoke different triggers of the autonomic nervous system. The measurements were performed and monitored by medical professionals at the university hospital Erlangen. The study was approved by the ethics committee of the Friedrich-Alexander-Universität Erlangen-Nürnberg (No. 85_15B). All research was performed in accordance with relevant guidelines and regulations. The informed consent was obtained from all subjects in human trials.<br><br>Due to size constrains the dataset is split in three zip files. Download the files and unzip them in one folder using a tool like "7zip" to get the whole database.<br>Important:<br>Information on how to use the database and the measurements can be found in the corresponding publication: https://www.nature.com/articles/s41597-020-00629-5<br>

本团队关于非接触式生命体征监测可行性的0期研究数据库，已在前序学术论文中发表。基于该数据集的分析结果显示，雷达系统除可采集脉搏与呼吸信号外，还能获取受试者的心音信号。心音具备清晰锐利的波形特征，可助力实现高精度心跳检测，这一精度对于心率变异性相关参数的测算至关重要。

在0期研究顺利完成后，本团队开展了雷达系统的临床评估工作。在1期研究中，研究人员采用雷达设备与同步参考设备——即Task Force Monitor（任务力量监测仪）——对30名健康受试者进行了数据采集。该参考设备不仅支持非接触式连续血压监测，还可采集心电图（ECG）、心阻抗图（ICG）及阻抗信号，并对原始信号进行分析处理，进而输出心率、每搏输出量、心输出量、胸腔液体含量、总外周阻力等多项生理参数。

除静息工况外，研究还设置了瓦尔萨尔瓦动作（Valsalva maneuver）、直立倾斜试验（tilt table test）及屏气等多种测试场景，以诱发自主神经系统产生不同应激反应。所有数据采集工作均由埃尔朗根大学附属医院的专业医护人员完成并全程监督。本研究已通过埃尔朗根-纽伦堡弗里德里希-亚历山大大学伦理委员会审查批准（审批编号：85_15B）。所有研究工作均严格遵循相关伦理准则与管理规范开展，人体试验受试者均已签署知情同意书。

受文件大小限制，本数据集被拆分为3个压缩包。请使用7zip等解压工具将所有压缩包下载后解压至同一文件夹，即可获取完整数据库。
