1·The sympathoadrenal system is unable to maintain cerebral perfusion pressure in the upright posture.
交感肾上腺系统不能维持直立位的脑灌注压。
2·On the other hand, Kurz et al have shown that IMA levels rose significantly after 4 hours in patients with and without reversible perfusion defects.34.
另一方面，Kurz等人的研究表明：无论患者是否患有可逆性灌注缺损，IMA水平都会在4小时之后显著升高(文献34)。
3·The key goal is the establishment of adequate tissue perfusion and oxygenation.
目标的关键是建立适当的组织灌注和氧。
4·Atthe time of this writing, clinical performance data are pending from amultitude of ongoing single and multi center trials to establish the role of CT perfusion in the diagnostic algorithm of CAD.
正当撰写这篇文章的时候，来自众多的单和多中心测试进行中的临床性能数据正期待着CT灌注在CAD诊断方法中所起的作用。
5·Vasopressors are used in shock-states to increase mean arterial pressure (MAP) and improve distal tissue perfusion. Additionally, some agents have effects on the heart to augment cardiac output.
血管升压药用于休克状态以提高平均动脉压（MAP）以及改善末梢组织灌注。此外，一些药物可以作用于心脏，增加心输出量。
