Pope Francis remains so stable that Vatican says next update will be provided on Saturday

ROME (AP) — Pope Francis remained in stable condition Thursday with no new respiratory crises or fever and worked from the hospital as he recovered from double pneumonia, the Vatican said.

Given the stability of Francis' condition, doctors said they didn’t expect to provide a new medical update until Saturday. His prognosis remains guarded, meaning he is not out of danger.

The Vatican said Francis continued respiratory and other physical therapy Thursday, worked, rested and prayed from the 10th floor papal suite at Rome's Gemelli hospital.

The pope has been sleeping with a non-invasive mechanical mask to guarantee that his lungs expand properly overnight and help his recovery. He has been transitioning to receiving high-flow oxygen with a nasal tube during the day. His routine now includes physical therapy, along with treatment for double pneumonia and respiratory therapy, Vatican officials said.

The 88-year-old pope, who has chronic lung disease and had part of one lung removed as a young man, has been stable for three full days after suffering a pair of respiratory crises Monday.

The Vatican said the evening Rosary prayer for Francis would be presided over by Cardinal Ángel Fernández Artime, the deputy official in charge of the Vatican’s department for religious orders. The department is actually headed by Sister Simona Brambilla, the first-ever nun named as prefect of a major Holy See office. But when Francis appointed her in January, he simultaneously named Artime as “pro-prefect” in a sign that he foresaw there were some functions that only an ordained priest can perform.

The pope was supposed to attend a spiritual retreat this weekend with the rest of the Holy See hierarchy. On Tuesday, the Vatican said the retreat would go ahead without Francis but in “spiritual communion” with him. The theme, selected before Francis got sick, was “Hope in eternal life.”
