准确的血压值,对診断具有重要的意义。然而,如何正确地进行血压測量和对所測之值作出正确的判断,却并非易事。因为每次所测之血压值受各种因素影响波动較大,下面就个人的体会結合文献談談影响血压值的因素問題。一、操作方法 1.压迫带:临床常用間接法測量血压,此法是以侧压法为其理論基础,而欲知側压值必需向血管壁周围加以外压,然后通过某种方法确定外压与側压之間的关系,再由已知之外压,得出側压值。通常皆采用压迫带确定外压值。压迫带之几何形状及大小又与
Accurate blood pressure, the diagnosis of great significance. However, it is not always easy to measure blood pressure correctly and correctly judge the measured value. Because each measured value of blood pressure fluctuations by a variety of factors, the following personal experience combined with the literature on the factors that affect the value of blood pressure. First, the method of operation 1 compression band: commonly used in clinical indirect measurement of blood pressure, this method is based on the side pressure method for its theoretical basis, and to know the side pressure value must be applied to the external pressure around the vessel wall, and then by some method to determine The relationship between pressure and lateral pressure, and then known by the pressure, derived lateral pressure value. Pressure belt are usually used to determine the value of external pressure. Compression with the geometric shape and size and
