腕式电子血压计测量血压的可靠性依赖于是否将其正确摆放在心脏水平的位置,而先前未曾在现实生活中对普通人群使用仪器的可靠性进行研究。该研究纳入721名普通人群,以测定在使用腕式血压计自测血压时是否普遍存在测量误差。方法:接受训练后,受试者分别用UA-767上臂式电子血压计和UB-542腕式电子血压计(没有设置位置传感器)在诊室和家里各测一次血压。以诊室测量的上臂血压值作为参考值。诊室和家庭血压测量值之间的差异定义为家庭血压测
The reliability of a wrist-type sphygmomanometer to measure blood pressure depends on whether it is correctly positioned at the heart level or not, and the reliability of instruments used in the general population has not previously been studied in real life. The study enrolled 721 general population to determine if there was a widespread measurement error when using a wrist sphygmomanometer to measure blood pressure self. METHODS: After training, subjects measured blood pressure in the office and at home using the UA-767 upper arm blood pressure monitor and the UB-542 wrist-type blood pressure monitor (without a position sensor). The upper arm blood pressure measured by the clinic as a reference value. The difference between office and home blood pressure measurements is defined as home blood pressure
