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>
