With the increasing demand for accurate BP measuring devices there comes also the need for validation. Most validation procedures assess the accuracy of a test device against a known standard, most commonly a mercury sphygmomanometer. The best method for assessing device accuracy is to measure BP simultaneously in the same arm with the test device and a mercury sphygmomanometer. This is not always possible because the deflation mechanism of the test device interferes with the ability of an observer to auscultate the Korotkov sounds accurately. In this study a mathematical method of sequential comparison between the test device and a mercury standard in the same arm is described which is almost as accurate as simultaneous measurement in the same arm.
随着对精确血压测量设备需求的增加，对其进行验证的需求也随之而来。大多数验证程序是根据已知标准（最常见的是汞柱血压计）来评估测试设备的准确性。评估设备准确性的最佳方法是使用测试设备和汞柱血压计在同一手臂同时测量血压。但这并非总是可行，因为测试设备的放气机制会干扰观察者准确听诊柯氏音的能力。本研究描述了一种在同一手臂中对测试设备和汞标准进行顺序比较的数学方法，其准确性几乎与在同一手臂同时测量相同。
