Cuff-based blood pressure measurement: challenges and solutions.

OBJECTIVE Accurate measurement of arterial blood pressure (BP) is crucial for the diagnosis, monitoring, and treatment of hypertension. This narrative review highlights the challenges associated with conventional (cuff-based) BP measurement and potential solutions. This work covers each method of cuff-based BP measurement, as well as cuffless alternatives, but is primarily focused on ambulatory BP monitoring. RESULTS Manual BP measurement requires stringent training and standardized protocols which are often difficult to ensure in stressful and time-restricted clinical office blood pressure monitoring (OBPM) scenarios. Home Blood pressure monitoring (HBPM) can identify white-coat and masked hypertension but strongly depends on patient adherence to measurement techniques and procedure. The widespread use of nonvalidated automated HBPM devices raises further concerns about measurement accuracy. Ambulatory blood pressure measurement (ABPM) may be used in addition to OBPM. It is recommended to diagnose white-coat and masked hypertension as well as nocturnal BP and dipping, which are the BP values most predictive for major adverse cardiac events. Nonetheless, ABPM is limited by its non-continuous nature and susceptibility to measurement artefacts. This leads to poor overall reproducibility of ABPM results, especially regarding clinical parameters such as BP variability or dipping patterns. CONCLUSIONS Cuff-based BP measurement, despite some limitations, is vital for cardiovascular health assessment in clinical practice. Given the wide range of methodological limitations, the paradigm's potential for improvement is not yet fully realized. There are impactful and easily incorporated opportunities for innovation regarding the enhancement of measurement accuracy and reliability as well as the clinical interpretation of the retrieved data. There is a clear need for continued research and technological advancement to improve BP measurement as the premier tool for cardiovascular disease detection and management.
