Valencell ear bud blood pressure measurement

At the Consumer Electronics Show in Las Vegas two months ago, biometric device maker Valencell (Raleigh, NC) previewed its blood pressure tracking ear bud.  “Valencell used over 15,000 datasets from about 5,000 subjects from different ages and demographics, including 25% using blood pressure medication, to develop its blood pressure algorithms, and then clinically tested over 600 measurements from over 130 subjects to get readings that now fall within plus or minus 8mm of mercury degree of error that blood pressure cuffs have. Valencell admits the measurements aren’t medical grade yet, and high blood pressure measurements can still be problematic.” MORE
