大鼠是心血管系统生理、药理和病理生理实验研究的常用动物,因而大鼠各项心功能指标测定方法的建立很受重视。泵功能是血液动力学的重要指标,测定大鼠泵功能的方法很多,自1972年以来国外陆续有应用电磁流量计测定大鼠心输出量(CO)的文献,但国内至今未见到这方面的资料,而且很少见到在增加容量负荷时正常大鼠泵功能变化的报道。本文报道应用电磁流量计测
Rat is a common animal used in the physiological, pharmacological and pathophysiological experiments of cardiovascular system. Therefore, the establishment of various cardiac function indexes in rats has drawn great attention. Pump function is an important index of hemodynamics. There are many ways to measure the function of rat’s pump. Since 1972, foreign countries have successively applied the electromagnetic flowmeter to measure the cardiac output (CO) of rats, but so far no such information has been found in China , And few reports of changes in pump function in normal rat at increased volume load are rare. This article reports the use of electromagnetic flowmeters
