Blood pressure measurement is an essential, poorly performed skill, traditionally undertaken through auscultation and use of a mercury sphygmomanometer. However, its exclusivity to the clinical environment has changed substantially over the last 20 years with the introduction of automated blood pressure devices. This simplified self-measurement method has enabled increased patient involvement and surveillance, while also eliminating the observer error, measurement bias and white-coat effect associated with auscultatory measurement in the clinical setting. Rapid advances in technology have decreased the discrepancy between automated and auscultatory readings, evidenced by the increased number of devices to pass recognized validation standards. However, the limitation of automated device accuracy is still evident in certain patient groups, such as those with diabetes, an arrhythmia or preeclampsia. Therefore, careful consideration is warranted when selecting a noninvasive blood pressure measurement device to ensure optimum accuracy and reliability of readings.
血压测量是一项重要但执行情况不佳的技能，传统上是通过听诊和使用汞柱血压计进行的。然而，在过去20年里，随着自动血压测量设备的引入，其仅限于临床环境的情况已发生了很大变化。这种简化的自我测量方法增加了患者的参与度和监测，同时还消除了临床环境中与听诊测量相关的观察者误差、测量偏差和白大褂效应。技术的快速发展减少了自动测量和听诊测量读数之间的差异，通过达到公认验证标准的设备数量增加得到了证明。然而，自动设备准确性的局限性在某些患者群体中仍然很明显，比如患有糖尿病、心律失常或先兆子痫的患者。因此，在选择无创血压测量设备时需要仔细考虑，以确保读数的最佳准确性和可靠性。
