“XxXlxX”血压忽高忽低XxXlxX?了解一下测血压的常见误区|科普时间

  血压XxXlxX忽高忽低?

XxXlxX

  李阿姨患高血压好几年了,女儿帮她买了台电子血压计,在家也定期会测血压。最近,李阿姨发现自己在家里测的血压一直很稳定,就放松了警惕,高血压药也吃吃停停。这天她来社区医院配药,顺便在候诊室测个血压,没想到收缩压超过160mmHg了。

  李阿姨感到很奇怪,她明明出门前测过血压是正常的,怎么一到医院就这么高?是不是医院的血压计不准?

  血压与我们的健康息息相关,掌握正确的测压方法,知晓自己的血压,是预防和控制高血压及其相关并发症的基础。

  可能会影响血压测量结果的情况

  01 血压偏低

  测量时室温较高;测量中气囊高于心脏水平、袖带捆绑过紧等。

  02 血压偏高

  测量时室温较低、环境嘈杂、情绪紧张;测量前饱餐、吸烟、饮酒或咖啡、膀胱充盈;测量中气囊低于心脏水平、袖带捆绑过松、仅测量一次等。

  误区解读

  不同人测血压可以用同一种袖带

  袖带气囊应至少覆盖80%上臂周径,太松会导致测量结果偏高,而太紧则会导致结果偏低。袖带的大小应该适合患者上臂臂围,常规袖带长22~26厘米,宽12厘米,上臂臂围大者(>32厘米)应换用大规格袖带,而臂围小者(<17厘米)应用小规格袖带。

  血压每次测1次就可以了

  我们自己测量血压时,通常测1次就结束了,但这其实是不够的。按照规范的测量流程,每次测量血压时应连续测2次,间隔1~2分钟,取2次的平均值,如果2次结果差异>10mmHg,则应该测量第3次,然后取3次的平均值记录。因此,我们在测量前,要先安静休息5分钟,防止2次测量的结果差异过大。

  量血压只测一只手臂

  一般来说,每个人左手和右手的血压不完全一样,首次测量血压时,双上臂的血压都需要测量,以后测量读数较高的一侧。这样除了能明确哪只手血压更高外,也能知道自己的双臂血压差值。

  正常情况下,双臂血压差应在10mmHg以内,如果大于10mmHg就应该提高警惕,可能存在血管狭窄甚至堵塞的情况,或者有其他导致继发性高血压的疾病,应尽快转诊做进一步诊断。
