ROME — Pope Francis was conscious but still receiving high flows of supplemental oxygen Sunday following a respiratory crisis and blood transfusions, as he remains in critical condition with a complex lung infection, the Vatican said.

Pope Francis, in critical condition with a complex lung infection, rested well during a peaceful night following a respiratory crisis and blood transfusions, the Vatican said Sunday. Vatican spokesman Matteo Bruni's one-line statement early Sunday didn't mention if Francis was out of bed or eating breakfast.

The announcement on Saturday evening indicated that Francis’ medical condition had become more complicated since an update from his doctors on Friday.
