Why the study?
Smartphone-based oscillometric blood pressure measurement requires measuring applied arterial pressure and local blood volume change, leading investigators to develop a force estimation method without specialized hardware.
Does a smartphone-based oscillometric method using Vibrometric Force Estimation accurately measure blood pressure compared to an FDA approved BP cuff?
Does a smartphone-based oscillometric method using Vibrometric Force Estimation accurately measure blood pressure compared to an FDA approved BP cuff?
A novel smartphone-based oscillometric blood pressure measurement technique using vibrometric force estimation showed a mean absolute error of ~9/8 mmHg compared to a standard cuff, suggesting potential for low-barrier hypertension screening.
