The effect of perfusion rate on pulmonary blood flow distribution in isolated rabbit lung.
碩士 === 國防醫學院 === 海底醫學研究所 === 96 === 中文摘要 低血容性休克是因為全身性有效血量降低,使得心輸出量降低,肺動脈壓降低,並且使肺血管阻力增加,進而影響了氧氣的運送。正常的生理代償機制應該是提升氧氣供應量回復組織的需氧量。 已知動脈血氧分壓間接反應氧氣含量及通氣-灌流分布,過去文獻中的結果發現休克造成動脈血氧分壓表現不一致,是否因為心輸出量的改變造成肺血流重新分布,改善肺臟氣體交換而使得動脈血氧分壓增加,提高氧氣輸送能力。為了減少活體動物心輸出量不易控制及神經反應等變數,故選用兔子離體肺模式來觀察灌流量對於肺血流重分布的影響。實驗根據灌流量的增減順序分成三組,控制...
