In 166 patients attending a hypertension review clinic, we compared supine and sitting blood pressure measurements and first and second measurements (1 min apart) in each position to determine whether any differences seen might have implications for the routine measurement of blood pressure in these patients, as a group or as individuals. Measurements were made with the Copal UA-251 semi-automated sphygmomanometer. In the group there was no significant difference between the first and the second diastolic measurements. The first systolic measurement was on average 3-4 mmHg higher than the second in both positions. Mean supine systolic pressures were 2-3 mmHg higher and diastolic pressures 2-3 mmHg lower than the corresponding sitting pressures. In individual subjects there were substantial disagreements between successive measurements in both positions and between positions. However, these differences would not have influenced blood pressure management in more than a few instances. We suggest that two measurements should routinely be taken, and the average recorded, particularly when the average exceeds 155/90 mmHg.
在一家高血压复查诊所就诊的166名患者中,我们比较了仰卧位和坐位的血压测量值,以及每个体位下的首次和第二次测量值(间隔1分钟),以确定所观察到的任何差异是否会对这些患者群体或个体的常规血压测量产生影响。使用科帕UA - 251半自动血压计进行测量。在该组中,首次和第二次舒张压测量值之间没有显著差异。在两个体位下,首次收缩压测量值平均比第二次高3 - 4 mmHg。仰卧位平均收缩压比相应的坐位高2 - 3 mmHg,舒张压低2 - 3 mmHg。在个体受试者中,两个体位下连续测量值之间以及体位之间存在很大差异。然而,这些差异在少数情况下才会影响血压管理。我们建议常规应进行两次测量,并记录平均值,特别是当平均值超过155/90 mmHg时。
