Objective To study the effect of Amrinone on hemodynamics,blood gas analysis and respiratory function in patients with pulmonary hypertension of chronic obstructive pulmonary disease(COPD).

目研究力农对COPD患者肺动脉高压时血流动力学、血气分析和肺功能作用。方法测定COPD患者肺动脉高压时力农疗前声心动图、血气分析和肺功能作用。

Flow chamber is one of the most effective equipment to study the response about blood corpuscle and endothelioid cells under the condition of hemodynamics in vitro.

流动腔装置广泛用于体外研究流动环境中细胞力学行为,是研究细胞粘附及应力与生长关系特性主要手段之一。

MB leads little changes of hemodynamics due to inhibit cardiac sympathicotonia and pneumogastric nerve simultaneity, but TEB brings the evident changes due to only inhibit pneumogastric nerve.

纵隔阻滞与硬膜外阻滞相比，硬膜外阻滞抑制交感神经，引起明显血流动力学变化，而纵隔阻滞同时抑制心交感和心迷走神经，不引起明显血流动力学变化。
