Maintain normal cerebral perfusion pressure by avoiding hypotension and cerebral retraction. 維持正常腦灌注壓。
We should guarantee that the perfusion pressure of brain tissue is normal when we take on antihypertensive treatment for patients with TIA. 即在保證腦組織灌注壓的情況下，將血壓控制到合適的程度。
Cerebral perfusion decreases as the intracranial pressure is raised.Irreversible ischemic change occurs when cerebral perfusion pressure is below 40 mmHg. 顱內高壓發生時相對的腦灌流壓下降，腦部的循環便受到影響，當顱內高壓無法控制而腦灌流持續低於四十毫米汞柱時腦部終至缺血而死。
Base on the wellbore tempera-ture dstribution model in this paper, computing the wellbore pressure distribution in the base of homogen method. 以本文井筒溫度分佈計算模型為依據，借鑒均質模型的井筒壓力求解方法計算井底流壓。
