suggested as much observing?

In addition, a prominent feature of TICS is severe hypoproteinemia.In ARDS alveolar edema has a protein concentration similar to plasma (ie. > 75%),so that TICS-induced hypoproteinemia lowers edema viscosity; thereby reducing the “yield pressure” and time needed to recruit obstructed peripheral airways and redistribute edema from the alveolar space.This likely enhances the efficacy of recruitment to a greater extent than what otherwise occurs in ARDS without overhydration (eg. pneumonia). Ashbaugh and colleagues suggested as much observing that PEEP appeared to “reverse the syndrome” in fluidoverloaded trauma subjects.This gave rise to the illusion of PEEP as “curative”. In contrast, Ashbaugh and colleagues observed that in ARDS associated with pneumonia or aspiration “the illness was likely to be prolonged and refractory to treatment”.

此外，TICS(毛细血管渗漏综合征)的一个突出特征是重度低蛋白血症。在ARDS中，肺泡水肿液的蛋白浓度与血浆相似(即>75%)，因此TICS诱导的低蛋白血症降低了水肿粘度，从而增加了“渗出可能”和减少了恢复阻塞的外周气道和液体从肺泡空间重新分布所需的时间。相比没有过度液体饱和的ARDS(如肺炎导致的ARDS)，伴TICS的ARDS可能在更易复张。Ashbaugh和他的同事们认为，观察到PEEP似乎可以“逆转”流体超负荷创伤受试者的ARDS。这导致了对PEEP的错觉，认为它是“治愈性的”。相反，Ashbaugh和他的同事观察到，在与肺炎或吸入有关的ARDS中，使用PEEP后“病程可能会延长并难以治疗”。

1.yield pressure啥意思？ reducing the “yield pressure”翻译成“增加了“渗出可能””意思是不是差不多

2.suggested as much observing

as much也； 同样

Business surveys certainly suggest as much. 

经济调查亦显示如此。

那suggested as much observing怎么理解？

是：Ashbaugh and colleagues suggested the same (phnomenem as other's mentioned previously) and observed that ... 吗？

那这里的suggest该怎么翻译？

3.In contrast, Ashbaugh and colleagues observed that in ARDS associated with pneumonia or aspiration “the illness was likely to be prolonged and refractory to treatment”.

相反，Ashbaugh和他的同事观察到，在与肺炎或吸入有关的ARDS中，使用PEEP后“病程可能会延长并难以治疗”。

这句话理解的对吗？文献太早，没查到原文
