腕式血压监测仪的准确度如何？
回答 Francisco Lopez-Jimenez 博士
一些腕式血压监测仪可提供准确的结果，只要严格按照说明使用并在医务人员诊室核对测量结果即可。为获得最可靠的血压测量结果，美国心脏协会建议尽量选择带包裹上臂的袖带的监测仪。
一些手臂尺寸较大的人可能无法在家中找到合适的袖带。在这种情况下，可以测量手腕处的血压。对于已切除腋窝淋巴结（腋下淋巴结切除术）的人群，腕式血压监测仪也可能是一种选择。
在家里使用腕式血压监测仪时，常会由于放置不当获得错误的高读数。使用这种监测仪时，请将其直接放置于手腕动脉（桡动脉）上，该位置可以感觉到脉搏。请勿将其放置在衣服上。保持手腕与心脏水平。检测期间，保持不动，且避免弯曲手腕。弯曲（屈曲）手腕可能导致读数错误。
在家里各类监测仪上测得的血压读数与在医务人员诊室测得的血压读数经常不同。如果您有腕式血压监测仪，请将设备带至医务人员诊室。医务人员可以比较您手臂和手腕的血压，以确保您的设备正常工作。
