目前在生理及病理生理实验或研究中,最常用的动物是兎子.一般测量兎子血压的方法,将动脉套管直接插入颈总动脉,并与水银检压计相连.由水银检压计上观察动脉血压.用这种方法测量兎血压的缺点很多,主要是用枸椽酸钠作抗凝剂时,血压中的钙离子取代了钠离子,而钠离子可使心肌舒张容易影响心肌的收缩力,发生心脏扩张而造成动物死亡.如果用10%食盐代替枸椽酸钠,则动脉套管中的血液容易发生凝固,
Currently in physiological and pathophysiological experiments or studies, the most commonly used animal is prickly heat.Generally measure the prickly heat of the blood pressure method, the arterial cannula directly into the common carotid artery, and the mercury detector connected by a mercury viseometer On the observation of arterial blood pressure.This method of measuring blood pressure of many shortcomings, mainly sodium citrate anticoagulant, the blood pressure of calcium ions replaced sodium ions, and sodium ions can make myocardial relaxation easily affect the myocardium Contractility, cardiac dilatation and cause animal death.If you use 10% salt instead of sodium citrate, the arterial cannula in the blood prone to coagulation,
