怎么分析此句?Thanks!However,in all cases,patients should receive the best possible treatment for as long as there is hope of recovery before such a decision is considered.

这句话的主干是 patients should receive the best possible treatment ,for后面接的是一个原因状语,as long as是只要的意思,before后面接了一个时间状语
然而,任何情况下,在做这个决定之前,只要病人有康复的希望,他们都应该得到尽可能最好的治疗.
