Key result
A chair-based cuffless blood pressure monitoring system estimated systolic and diastolic BP with a mean difference of 0.2 ± 5.8 mmHg and 0.4 ± 5.7 mmHg compared to a reference cuff monitor.

A novel chair-based cuffless blood pressure monitoring system using pulse arrival time provides accurate BP estimations comparable to cuff-type monitors, showing potential for long-term home monitoring.
Tang et al. (2016) studied Blood pressure monitoring (n=10). Chair-based unobtrusive cuffless blood pressure monitoring system vs. Cuff-type BP monitor was evaluated on Accuracy of estimated systolic and diastolic blood pressure (Mean difference 0.2 ± 5.8 mmHg for SBP and 0.4 ± 5.7 mmHg for DBP, p=<0.00001). A chair-based cuffless blood pressure monitoring system estimated systolic and diastolic BP with a mean difference of 0.2 ± 5.8 mmHg and 0.4 ± 5.7 mmHg compared to a reference cuff monitor.
