Does smartphone-based transdermal optical imaging accurately measure blood pressure in normotensive adults compared to reference measurements?
Smartphone-based transdermal optical imaging shows promising accuracy for blood pressure measurement in normotensive adults, but requires further validation across a wider range of blood pressures.
Our results in normotensive adults fall within 5±8 mm Hg of reference measurements. Future work will determine whether these models meet the clinically accepted accuracy threshold of 5±8 mm Hg when tested on a full range of blood pressures according to international accuracy standards.
