Key result
A patient-specific oscillometric BP measurement method yielded root-mean-square-errors of 6.0 to 9.3 mmHg, which were nearly 40% lower than existing fixed-ratio methods and a current office device.

Does a patient-specific oscillometric BP measurement method improve accuracy compared to conventional fixed-ratio methods in patients with varying pulse pressures?
A novel patient-specific oscillometric BP measurement method significantly reduces measurement errors compared to conventional fixed-ratio methods.
Liu et al. (2015) studied widely varying pulse pressures (n=57). patient-specific oscillometric BP measurement method vs. fixed-ratio method and a current office device was evaluated on BP root-mean-square-errors. A patient-specific oscillometric BP measurement method yielded root-mean-square-errors of 6.0 to 9.3 mmHg, which were nearly 40% lower than existing fixed-ratio methods and a current office device.
