测量血压是日常医疗工作中经常要做的事情,但对于它的意义、升高或降低等变化意味着什么,如何正确地操作,进而怎样恰当地评定其数值,却有时被重视不足,以致影响诊疗效果。这里提出有关这方面的情况,以便引起重视。血压是什么血压是循环着的血液的一种势能,即血液在血管内流动时对血管壁所产生一种压力,它主要来源于心脏收缩等动力。人和动物的循环系统是一个完整而密闭的管道系统。心脏收缩时把血液推进到动脉中去,并且靠压力使血液不断地前进。血液循行的途径是由左心室开始,依次经过主动脉、动脉、小动脉、毛细血管、小静脉、静脉和上、下腔静脉,最后
Measuring blood pressure is a regular exercise in daily medical work, but the implications for what it means to raise or lower, what to change, how to operate properly, and how to properly assess its value are sometimes overlooked Therapeutic effect. The situation here is raised in order to draw attention. What is blood pressure? Blood pressure is a kind of potential energy of circulating blood, that is, a pressure exerted on the blood vessel wall when blood flows in the blood vessel. It mainly comes from the power of systole and so on. The circulatory system of humans and animals is a complete and confined piping system. The blood is pushed into the artery when the heart contracts, and the pressure keeps the blood going. Blood circulation route from the left ventricle, followed by the aorta, artery, arterioles, capillaries, venules and veins, and inferior vena cava, and finally
