ABPM device accuracy may decline at high BP levels; leaves open whether range-specific validation alters device selection in practice.
Does the accuracy of ambulatory blood pressure measuring systems vary according to blood pressure levels?
The accuracy of ambulatory blood pressure monitors decreases at high blood pressure levels, highlighting the need to consider BP range when selecting devices for clinical practice.
Brien et al. (1993) studied Blood pressure measurement. Six ambulatory blood pressure measuring systems was evaluated on Accuracy grading according to the British Hypertension Society (BHS) protocol across low, medium, and high blood pressure ranges. The CH-Druck was the most accurate ambulatory blood pressure system across pressure ranges, though its grading slipped from A/A to B/C in the high blood pressure range.
