Monitoring Your Blood Pressure at Home
How to use a home blood pressure monitor
- Be still. 与你的医疗保健专业人员讨论如何使用你的家庭血压计. Don't smoke, 在测量血压前30分钟内喝含咖啡因的饮料或锻炼. 排空膀胱,确保在测量前至少安静休息五分钟.
- Sit correctly. 坐着时背部要挺直,要有支撑(坐在餐椅上,而不是沙发上)。. 你的脚应该平放在地板上,你的腿不应该交叉. 你的手臂应该支撑在一个平面上,比如桌子,上臂在心脏水平. 确保袖带的底部正好在肘部弯曲的上方. 查看你的监护仪的说明,或者让你的医疗保健专业人员告诉你如何做.
- Measure at the same time every day. 每天在同一线上电子游戏飞禽走兽做阅读是很重要的,比如早上和晚上. It is best to take the readings daily, 理想情况下,在治疗改变后两周和下次预约前一周开始.
- Take multiple readings and record the results. 每次测量时,间隔一分钟取两次读数,并用记录仪记录结果 printable (PDF) tracker. 如果你的显示器有内置内存来存储你的读数,带着它去约会. 有些监视器还允许你在注册个人资料后将读数上传到一个安全的网站.
- Don't take the measurement over clothes.

If you get a high blood pressure reading
- 如果你的血压高于180/120毫米汞柱,并且你正在经历可能的器官损伤的迹象,如胸痛, shortness of breath, back pain, numbness/weakness, change in vision or difficulty speaking, do not wait to see whether your pressure comes down on its own. Call 911, as this is an emergency.
- A single high reading is not an immediate cause for alarm. 如果你的读数略高于或中等高于正常水平, 第二次量血压,把两次测量的结果写下来. 咨询您的医疗保健专业人员,以确认是否有健康问题,或者您的监视器是否有任何问题.
- 如果你的血压读数突然超过180/120毫米汞柱,等待5分钟,再次测试. 如果您的读数仍然异常高,请立即联系您的医疗保健专业人员. You could be experiencing a hypertensive crisis.
AHA recommendation
美国心脏协会建议对所有高血压患者进行家庭监测,以帮助医疗保健专业人员确定治疗是否有效. Home monitoring, or self-measured blood pressure, is not a substitute for regular visits to your physician. If you have been prescribed medication to lower your blood pressure, 在没有咨询你的医疗保健专业人员之前,不要停止服药, 即使你的血压读数在家庭监测的正常范围内.
Choosing a home blood pressure monitor
美国心脏协会推荐一种袖口式的自动肱二头肌(上臂)监测器.
- 不建议使用手腕和手指监视器,因为它们的读数不太可靠.
- Choose a monitor that has been validated. 如果您不确定,请向您的医疗保健专业人员或药剂师寻求建议或在 validatebp.org(link opens in new window).
- When selecting a blood pressure monitor for a senior, pregnant woman or child, make sure it is validated for these conditions.
- 确保袖口合身——在你的上臂周围量一量,选择一个袖口尺寸合适的显示器.
Once you’ve purchased your monitor, bring it to your next appointment
让你的医疗保健专业人员检查一下,看看你是否正确使用了它,并得到了与办公室里的设备相同的结果. 计划每年带一次监测仪来检查,以确保读数准确.
Home blood pressure monitoring may be especially useful for:
- Anyone diagnosed with high blood pressure, also known as hypertension.
- 个体开始高血压治疗,以确定其有效性.
- People requiring closer monitoring, especially individuals with risk factors for high blood pressure and/or conditions related to high BP.
- Pregnant women experiencing pregnancy-induced hypertension and/or preeclampsia.
- Evaluating potentially false readings, like:
- 在医疗保健专业人员的办公室只有高读数的人(“白大褂”高血压).
- 只有在家里而不是在医疗保健专业人员的办公室有高读数的人(“隐性”高血压).
- NOTE: People with atrial fibrillation or other arrhythmias 可能不是家庭监测的好选择,因为电子家庭血压设备可能无法提供准确的测量. 请您的医疗保健专业人员推荐一种适合您的监测方法.
Left-arm versus right-arm blood pressure
为了确定左臂和右臂之间的正常差异,已经进行了几项研究. 一般来说,任何10毫米汞柱或更小的差异都被认为是正常的,不需要担心.
Why keep a blood pressure journal?
One blood pressure measurement is like a snapshot. It only tells what your blood pressure is at that moment. 一段线上电子游戏飞禽走兽内的读数记录提供了一个“延时”的血压图像,可以帮助你 partner with your physician to ensure that your treatments to reduce high blood pressure are working.
