Why the study?
Mobile health diagnostics effectively manage chronic diseases, but the accuracy and precision of the smartphone-based OptiBP technology over time required evaluation.
Does smartphone-based OptiBP technology accurately measure blood pressure compared to a non-invasive oscillometric brachial cuff in adult volunteers?
Population
65 adult volunteers without cardiac arrhythmias and minimal interarm blood pressure difference
Comparison
OptiBP smartphone-based BP estimation vs non-invasive oscillometric brachial cuff
Design
Prospective method comparison study

May support limited OptiBP testing for MAP and DAP; leaves open SAP accuracy and clinical adoption.
Does smartphone-based OptiBP technology accurately measure blood pressure compared to a non-invasive oscillometric brachial cuff in adult volunteers?
The smartphone-based OptiBP application showed acceptable agreement with standard brachial cuff measurements for mean and diastolic blood pressure, fulfilling ISO standards for these parameters but not for systolic pressure.
Delmotte et al. (2023) studied this question.
