结论COPD急性加重期较稳定期肺功能显著下降，肺过度充气和外周气道阻力增加是急性加重期肺功能恶化的主要原因。
Conclusions Pulmonary function of COPD decreased significantly from stable stage to exacerbation, the main reasons of which were hyperinflation and the increasing of peripheral airway resistance.
它们主要特征分别表现为：血管型以增加外周阻力为主；
The regulating characteristics of vascular type mainly showed an increase of total peripheral resistance during stress.
因为患者外周阻力降低，而心输出量增加。
In patients, because they have decreased peripheral resistance they have high cardiac output.
促进机体脂类代谢；增加血管弹性，降低外周阻力；
To reduce cholesteral and glycerine, promote body's metabolize, improve blood vessel elasticity.
提示急性心肌梗死患者口服氯沙坦产生外周阻力及心肌耗氧量下降，心指数增加等有益的血流动力学效应。
The results showed that oral losartan administrated to patients with ami resulted in beneficial hemodynamic effects, such as decrease of SVR and oxygen consumption, increase of cardiac index.
结果：心通口服液可升高左室内压，增加左室作功，外周阻力下降。
Results: Xintong Oral Solution can raise the internal pressure of left ventricle, enhance the work of left ventricle and reduce the per...
