我们通常说的血压一般指动脉血压,即体循环血压,为血液流经动脉系统时对动脉管壁所呈现的侧压,是推动血液流动的驱动力。血压必须达到一定程度才能保证全身器官的血供。血压的形成取决于心脏射血能力、大动脉弹性、外周血管阻力和足够的血容量。 We usually say that the blood pressure is generally referred to as arterial blood pressure, that is, systemic blood pressure, blood flow through the arterial system presented to the artery wall pressure, is to promote blood flow driving force. Blood pressure must reach a certain level to ensure the blood supply to whole body organs. The formation of blood pressure depends on cardiac ejection ability, aortic elasticity, peripheral vascular resistance and adequate blood volume.
