Self-blood pressure monitoring can be critical in the management of hypertension, but it is often awkward and cumbersome. One attempt to improve the ease with which such measurements are made was the development of electronic, digital, automatic monitors for measurement of blood pressure in the finger. The purpose of this study was to evaluate the accuracy, reliability, failure rate, and ease of operation of these devices. While these finger devices were found easier to use than the traditional brachial-artery methods, their accuracies and reliabilities were lower. The greater responsiveness of the digital arteries to changes in local conditions is suggested as the cause of the lesser accuracy and reliability. The author concludes that blood pressure in the digital arteries of the finger is not sufficiently representative of general systemic blood pressure for clinical purposes.
自我血压监测在高血压管理中可能至关重要，但它往往笨拙且麻烦。为提高进行此类测量的便捷性所做的一次尝试是开发用于测量手指血压的电子、数字自动监测仪。本研究的目的是评估这些设备的准确性、可靠性、故障率和操作简便性。虽然发现这些手指设备比传统肱动脉方法更易于使用，但其准确性和可靠性较低。数字动脉对局部状况变化的更大反应性被认为是准确性和可靠性较低的原因。作者得出结论，就临床目的而言，手指数字动脉中的血压不足以代表一般全身血压。
