Cambridge researchers found that low downstream pressure in the arm can cause blood pressure cuffs to underestimate systolic readings, missing many hypertension cases. Scientists have uncovered the reason why standard cuff-based blood pressure tests often produce inaccurate results and identified ways to make them more precise. Improving these measurements could have a major impact on […]



Summary

Cambridge researchers discovered that low downstream arm pressure causes standard blood pressure cuffs to underestimate systolic readings, leading to missed hypertension diagnoses. This inaccuracy stems from the cuff’s indirect measurement, influenced by arm-specific blood flow dynamics. Identifying the cause of this discrepancy allows for developing more precise measurement techniques. Improving the accuracy of blood pressure measurements is crucial for better hypertension management and potentially significant health outcomes.
