Ubiquitous blood pressure monitoring using EEG and PPG signals

The Vita-H1 system represents an innovative way of accurately predicting systolic and diastolic blood pressures using PPG and ECG signals. As a cuff-less system, Vita-H1 allows convenient continuous BP monitoring throughout the day. Based on a test set of 90 people, the mean absolute bias for SBP (|H1 - true|) is 5.4mmHg and for DBP is 4.4mmHg, which complies with the IEEE1708--2014standard (MAD<=7mmHg). The Vita-H1 combines big data analytics based on a large training data and individual predictive analytics based on individual caliber data. The big data analytic is performed on a remote server and the results are downloaded to the smart-phone app. Individual updates can be computed off-line and real-time on the smart-phone.
