President Trump’s physician, Dr. Sean Conley, said he is continuing "to improve" but, as with any illness, "there are frequent ups and downs," he said a news briefing from Walter Reed National Military Medical Center in Bethesda, Maryland.
"Over the course of his illness, the President has experienced two episodes of transient drops in his oxygen saturation. We debated the reasons for this, and whether we'd even intervene. It was a determination of the team based on the timeline from the initial diagnosis that we initiate dexamethasone," Conley said.
Dexamethasone is a widely available steroid drug.
Conley said the President was given supplemental oxygen and his current blood oxygen level is 98%.
Conley refused to say how low the President's blood oxygen levels had dropped. When asked if they had dropped below 90, he replied, "We don't have any recordings here of that."
When asked again on whether they had dropped below 90, Conley said the President's blood oxygen levels didn't get down into "the low 80s."
