Improved agreement and diagnostic accuracy of a cuffless 24-h blood pressure measurement device in clinical practice.

ABSTRACT: A cuffless blood pressure (BP) device (TestBP) using pulse transit time is in clinical use, but leads to higher BP values compared to a cuff-based 24 h-BP reference device (RefBP). We evaluated the impact of a recent software update on BP results and TestBP's ability to differentiate between normo- and hypertension. 71 individuals had TestBP (Somnotouch-NIBP) and RefBP measurements simultaneously performed on either arm. TestBP results with software version V1.5 were compared to V1.4 and RefBP. Mean 24 h (±?SD) BP for the RefBP, TestBP-V1.4 and TestBP-V1.5 were systolic 134.0 (±?17.3), 140.8 (±?20) and 139.1 (±?20) mmHg, and diastolic 79.3 (±?11.7), 85.8 (±?14.1) and 83.5 (±?13.0) mmHg, respectively (p-values?
