Pope Francis rested early Tuesday after he suffered further setbacks in his fight against double pneumonia: two new acute respiratory crises that required him to resume using noninvasive mechanical ventilation to breathe.

Pope Francis experienced more respiratory problems and went on noninvasive ventilation on Monday, the Vatican said, as the head of the Roman Catholic Church battles double pneumonia in the hospital.

Francis suffered the two crises Monday. Doctors extracted “copious” amounts of mucus that had accumulated in his lungs, the Vatican said in a late update.
