本文分别给六只家兔注射血管收缩药或血管扩张药,同步记录肺血流图波形和肺动脉压力曲线,比较注药前后的肺血流图波形、肺血流图波高、Z前后变化量与肺动脉脉压前后变化量之间的关系,观察肺血流图下降支与肺静脉压力间的关系。实验结果表明,肺阻抗血流图波高与肺动脉脉压成正比的关系。
In this paper, six rabbits were injected with vasoconstrictor or vasodilator respectively. The waveforms of pulmonary blood flow and pulmonary arterial pressure were recorded simultaneously. The waveforms of pulmonary blood flow, wave height of pulmonary blood flow, Pulmonary artery pulse pressure changes before and after the relationship between the observed pulmonary blood flow descending branch and the relationship between pulmonary venous pressure. The experimental results show that the pulmonary impedance blood pressure wave height and pulmonary artery pulse pressure is proportional to the relationship.
