目的：研究大鼠心血管内血液压强的分布。方法：实验动物采用Wistar大鼠n ＝15 。在封闭条件下用4导生理记录仪记录大鼠心血管系统内各部位的血液压强。本方法较传统的液体检压计法更为精确。结果：本实验得出大鼠心血管系统内血液压强的分布及其特点为：（1）左室收缩压（LVSP ）为（145．00±15．61） mmHg 主动脉收缩压（ASP ）为（126．87±11．16） mmHg 即LVSP高于ASP 右室收缩压RVSP 为（35．04±3．95） mmHg 肺动脉收缩压PASP 为（27．03±3．46） mmHg 即RVSP高于PASP。上述血液压强的分布与人类有所差异。（2）大鼠血管系统各部位压强（包括ASP、ADP、MAP、PASP、PADP、MPAP、CVP、WP ）的数值大小和变化范围大致与人类相同。结论：（1）大鼠的LVSP高于ASP，RVSP高于PASP ，此血压分布不同于人类。（2）与人类相比，大鼠的LVSP和RVSP较高，而其血管系统各部位的血液压强的大小和分布情况大致与人类相同。
Objective: To study the distribution of cardiovascular pressure in rats. Methods: The experimental animals were n = 15 Wistar rats. Under confinement conditions, the blood pressure of various parts of the cardiovascular system of the rat was recorded with a 4-channel physiological recorder. This method is more accurate than the traditional liquid pressure gauge. Results: The distribution and characteristics of blood pressure in the rat cardiovascular system were as follows: (1) LVSP was (145.00 ± 15.61) mmHg Aortic systolic pressure (ASP) was (126.87 ± 11.16) mmHg, LVSP was higher than RV RV RV RVSP (35.04 ± 3.95) mmHg PASP was (27.03 ± 3.46) mmHg RVSP was higher than PASP. The distribution of blood pressure and human differences. (2) The magnitude and the range of the changes in pressure (including ASP, ADP, MAP, PASP, PADP, MPAP, CVP and WP) in various parts of the rat vasculature are roughly the same as those in humans. Conclusion: (1) LVSP in rats is higher than ASP and RVSP is higher than PASP. The distribution of blood pressure is different from that in humans. (2) LVSP and RVSP were higher in rats than in humans, and the magnitude and distribution of blood pressure in various parts of the vasculature were roughly the same as in humans.
