【摘 要】 目的 了解无创性血压测量由坐位改为卧位后其测量数值的变化。 方法 对100例被观察者分别进行坐、卧位血压测量，坐卧位的先后次序随机交替，对测量结果进行统计学分析。 结果 卧位收缩压和舒张压均较坐位升高，差异均有显著性(P<0.05)，≥55岁组较<55岁组影响明显减少，差异有显著性(P<0.05)。 结论 无创性血压测量的数值卧位高于坐位，这种体位性影响随年龄的增加而减少。

    【Abstract】 Objective To investigate the changes of value when blood pressure is measured in differnt body positions.Methods 100subjects were selected and their blood pressure was measured in both sitting and lying positions，which were alternated randomly.The outcome of the measurement was statistically analyzed.Results Both systolic pressure and diastolic pressure of the lying position were higher than those of the sitting position.The difference was highly significant.The effect on the≥55years group was smaller than it was on the<55years group(P<0.05).Conclusion The value of non-invasive blood pressure measurement derived from the lying position is higher than the sitting position.The effect of the body position decreases with the rise of age. ......
