太低，不足以增加或甚至可能维持？

Not all blood components are depleted equally in hemorrhage [15]. An European expert meeting concluded that fast and targeted therapy for bleeding-induced coagulation factor deficiency is only possible with coagulation factor concentrates as the concentrations of coagulation factors, including fibrinogen, in FFP are too low to increase, or possibly even maintain, already low plasma concentrations in a bleeding patient [3]. A nontargeted, empirical approach to fibrinogen replacement is unlikely to be an optimal and cost-effective strategy [67].

出血时，并非所有血液成分都被同等地消耗。一次欧洲专家会议得出结论，只有使用凝血因子浓缩物才能对出血诱导的凝血因子缺乏进行快速和靶向治疗，因为FFP凝血因子(包括纤维蛋白原)的浓度太低，不足以增加或甚至可能维持出血患者已经很低的血浆浓度。非靶向的、经验性的纤维蛋白原补充不太可能是最佳且经济有效的策略。

太低，不足以增加或甚至可能维持？太低，不足以增加，那么就有可能是减少，那么怎么能甚至可能维持，甚至总应该是更差了，维持总比减少好
