Abstract The oscillometric method is the predominant technique for non-invasive blood pressure (BP) measurement worldwide, and has enabled widespread adoption of home BP monitoring, which is crucial for hypertension management. However, limitations in the usability of BP monitors, and particularly the pain and discomfort caused by excessive cuff inflation, can discourage consistent daily use of home BP monitors. To address this, we developed a novel oscillometric-based technology that reduces maximum cuff pressure (MaxCP) and measurement time while maintaining accuracy. We validated the performance of the novel method using a pre-existing dataset of oscillometric waveforms by comparing the estimated BP values with reference values obtained using the conventional method. The calculated BP values demonstrated high agreement with the conventional method, with intraclass correlation coefficients of 0.98 (systolic BP) and 0.94 (diastolic BP). Furthermore, the novel method reduced average MaxCP by 38.1 mmHg and measurement time by 6.3 s. These findings suggest that our approach can significantly enhance the user experience in BP monitoring without compromising measurement accuracy, potentially improving adherence to daily monitoring routines.
Ota et al. (2026) conducted an observational in Blood pressure measurement (n=85). Novel oscillometric method vs. Conventional oscillometric method was evaluated on Agreement of systolic blood pressure (SBP) with conventional method (ICC 0.98, p=<0.001). The novel oscillometric method demonstrated high agreement with the conventional method for systolic blood pressure (ICC 0.98) while reducing average maximum cuff pressure by 38.1 mmHg.
