不同体位无创血压监测值的比较及意义

The significance of blood pressure at varied body postures

目的 探讨体位因素对血压监测值的影响。方法 将 12 0例病人不同体位的血压监测值进行自身对照比较 ,对数据进行统计学处理。结果 (1)体位引起的血压波动与体位改变时测量手臂的位置高于或低于心脏有关。测量手臂位置高于心脏时 ,血压监测值降低 ;测量手臂的位置低于心脏时 ,血压监测值升高。 (2 )各种体位的左右臂血压监测值相差有显著性意义。结论 (1)体位改变对血压监测值有影响。 (2 )右侧卧位血压监测值较左侧相对恒定 ,采取右侧卧位监测血压时不必考虑体位因素。(3 )对连续血压监测的病人要记录监测时的体位和部位 ,以便在判断病情、作出诊断及决定治疗方案时排除体位因素 ,尤其是血压值在临界波动时 。

ObjectiveTo discuss the effect of postural factors on the blood pressure.MethodsBlood pressure was monitored and recorded at different postures in 120 patients by way of self comparison.ResultsThe observation indicated that blood pressure fluctuations caused by different body postures were relevant to whether arm is higher or lower than heart in position. Blood pressure taken at the left or right arm at different body postures varied significantly ( P <0.05).ConclusionPostural variations at examination pose obvious effect on blood pressure. Blood pressure taken at right sided sleeping position is more constant than that at right sided and the body postures need not be taken into consideration at examining the blood pressure at the right sided sleeping position. For those receiving continuous blood pressure monitoring, the exact posture and the position at examination have to be recorded in order to assist judging the degree of illness, making diagnosis and conduct appropriate treatment, especially when blood pressure fluctuates to the critical limit.
