Key result
Cuffless blood pressure monitoring using wrist-worn bio-impedance sensors accurately estimated post-exercise systolic (r=0.86, RMSE 3.4 mmHg) and diastolic BP (r=0.77, RMSE 2.6 mmHg).
Why the study?
Traditional cuff-based blood pressure measurement is bulky, obtrusive, and not applicable to continuous beat-to-beat monitoring, which provides significant advantages in predicting cardiovascular disease.
Can an array of wrist-worn bio-impedance sensors using subject-specific regression models accurately estimate post-exercise blood pressure in healthy young adults?
Population
10 healthy participants aged 18 to 30 years

A novel cuffless wrist-worn bio-impedance sensor array demonstrated proof-of-concept accuracy for estimating post-exercise blood pressure in healthy young adults.
Roozbeh Jafari (2019) conducted an observational in Healthy (n=10). Cuffless blood pressure monitoring using wrist-worn bio-impedance sensors was evaluated on Accuracy of post-exercise diastolic and systolic blood pressure estimation (r=0.77, RMSE 2.6 mmHg (diastolic); r=0.86, RMSE 3.4 mmHg (systolic)). Cuffless blood pressure monitoring using wrist-worn bio-impedance sensors accurately estimated post-exercise systolic (r=0.86, RMSE 3.4 mmHg) and diastolic BP (r=0.77, RMSE 2.6 mmHg).
