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如果严格按照说明使用并与在医务人员诊室获得的测量结果进行比对，可能提供准确的结果。为获得最可靠的血压测量结果，美国心脏协会建议您在可能情况下使用袖带包裹上臂的监测仪。
有些手臂非常粗大者可能无法找到能在家中使用的合适袖带。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者，腕式血压监测仪可能也是一种选择。
在家中使用腕式血压监测仪时，常会由于放置不当获得过高的错误读数。使用这种监测仪时，请将其直接放置于手腕动脉（即桡动脉）上可以感觉到脉搏的位置。请勿隔着衣服测量。保持手腕与心脏齐平。检测期间请保持不动，也不要弯曲手腕。弯曲手腕可能导致读数错误。
在家中使用任何类型的监测仪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。如果您有一台腕式血压监测仪，请将设备带至医疗护理专业人员诊室。医护团队可以比较您手臂和手腕的血压，以确保您的设备工作正常。
