Comparative evaluation of a novel multisensor device EYVA versus standard clinical sphygmomanometry for blood pressure measurement: a paired observational study

Background: Reliable and accessible blood pressure (BP) monitoring is vital for effective hypertension management. EYVA, a novel multisensor device, aims to provide accurate, non‑invasive BP measurement. We evaluated EYVA’s accuracy compared with standard clinical sphygmomanometry. Methods: A paired observational study involving 442 adult participants was conducted from June 2022 to August 2022. Blood pressure was sequentially measured using EYVA and a standard-of-care (SOC) sphygmomanometers under resting conditions. Paired t‑tests, Pearson correlation and Bland-Altman analyses assessed agreement and consistency between methods. Results: EYVA showed strong agreement with standard of care (SOC) for both systolic and diastolic BP. Mean systolic BP was 127.69±16.29 mmHg with EYVA and 126.77±16.90 mmHg with SOC, with a bias of 0.93 mmHg (p
