A series of measurements of blood pressure in normotensive and hypertensive subjects showed that measurements made with a sphygmomanometer with the arm dependent by the side were consistently higher than those made with the arm horizontal at heart level. The mean difference in a group of 90 hypertensive outpatients was 11/12 mm Hg. Failure to appreciate the importance of arm position may lead to erroneous measurements of blood pressure. This has important implications for clinical practice and research.
对血压正常和高血压患者进行的一系列血压测量表明,使用血压计测量时,手臂垂于身体一侧时测得的血压始终高于手臂与心脏水平齐平时测得的血压。在一组90名高血压门诊患者中,平均差异为11/12毫米汞柱。未认识到手臂位置的重要性可能会导致血压测量错误。这对临床实践和研究具有重要意义。
