足背动脉与肱动脉血压测定研究

随机抽取80名外科住院病人，进行自身对照实验研究。测定平卧位、左侧卧位、右侧卧位足背动脉血压及平卧位肱动脉血压值进行比较，以了解不同卧位对足背动脉血压的影响以及足背动脉血压与平卧位肱动脉血压间的关系。结果表明：3种卧位足背动脉血压值之间差异无统计学意义，足背动脉收缩压和舒张压极显著高于平卧位肱动脉收缩压和舒张压（P〈0．01），平卧位肱动脉与平卧位足背动脉收缩压之间和舒张压之间呈直线正相关，回归方程分别为：Y=29．76＋0．64x（R^2=0．67）；Y=15．38＋0．73x（R^2=0．52）。

Research on Measurement Foot Blood Pressure and Brachial Blood Pressure

Self-controlled experiment research has been made on 80 selected hospitalized patients at random. We have compared the blood pressure of supine position, left lateral position, right lateral position dorsal artery of foot blood pressure and supine position brachial blood pressure to study the impact of different lying position on foot blood pressure and the relationship between the blood pressure and supine position brachial blood pressure. We conclude that the differences among the three lying position foot blood pressure has no statistical significance. The systolic pressure and the diastolic blood pressure （P〈0.01） of foot blood pressure is obviously higher than that of supine position brachial blood pressure. The systolic pressure and the diastolic blood pressure（P〈0.01） of foot blood pressure and supine position brachial blood pressure exhibit positive linear correlation. Regression equations are： Y=29.76＋0.64X（R^2=0.67） ;Y=15.38＋0.73X （R^2=0.52）
