Why the study?
Oscillometric finger pressing is a potential method for smartphone-based absolute BP monitoring, but reliable computation algorithms needed to be developed and evaluated.
Does a smartphone-based oscillometric finger pressing algorithm accurately measure diastolic blood pressure compared to reference arm cuff measurements in human subjects?
Does a smartphone-based oscillometric finger pressing algorithm accurately measure diastolic blood pressure compared to reference arm cuff measurements in human subjects?
Analysis of oscillation width variations during finger pressing can improve diastolic blood pressure computation, potentially enabling cuffless smartphone BP monitoring.
