血氧85%是啥水平？

据霸道:But Conley refused to say how low the President''s blood oxygen levels haddropped. When asked if they had dropped below 90, he replied, "We don''t haveany recordings here of that." Pressed again on whether they had droppedbelow 90, Conley said the President''s blood oxygen levels didn''t get downinto "the low 80s."就算大夫说的是真话，血氧低值也不超过85%。

再高就要说high 80s了。
