Pope Francis, 88, was resting Monday morning, his 10th day at the hospital for a complex lung infection that led to the early stages of kidney insufficiency.
The Vatican said Pope Francis remained in critical condition Monday but showed slight improvement in laboratory tests and resumed some work.
The pontiff's condition is touch-and-go, given his age, fragility and pre-existing lung disease, according to doctors.
As of Friday, there was no evidence of any sepsis, and Francis was responding to the various drugs he is taking, the pope's medical team said in their first in-depth update on the pope's condition.
