Pope Francis has participated remotely in the Vatican's spiritual retreat after getting good news from his doctors. They upgraded his prognosis and say he is no longer in imminent danger of death as a result of pneumonia. The 88-year-old pope isn't out of the woods yet, however. Doctors are still cautious and have decided to keep him hospitalized for several more days to receive treatment, not to mention a period of rehabilitation he will likely need. The Vatican said Francis woke up Tuesday morning just after 8 a.m. after a quiet night.

Doctors said Pope Francis is no longer in imminent danger of death as a result of pneumonia but have decided to keep him hospitalized for several more days to receive treatment. In a late update, the doctors said on Monday the 88-year-old pope remains stable and has consolidated improvements in recent days, as determined by blood tests and positive responses to drug treatments. Francis followed the Vatican's weeklong spiritual retreat via videoconference as he continued his recovery from double pneumonia and looked ahead to the 12th anniversary of his election amid questions about what the future of his papacy might look like.

Pope Francis recorded a pained and labored audio message to thank people for their prayers for his recovery, the first public sign of life from the 88-year-old pope since he was hospitalized three weeks ago with double pneumonia. Francis' weak voice, discernible through his labored breaths and in his native Spanish, was broadcast to the faithful in St. Peter's Square who had gathered for the nightly recitation of the rosary prayer. "I thank you from the bottom of my heart for your prayers for my health from the square, I accompany you from here," he said, his soft voice piercing the hushed square. "May God bless you and the Virgin protect you. Thank you."

The Vatican says Pope Francis is in stable condition and breathing with just the help of supplemental oxygen after respiratory crises a day earlier. But he will resume using a ventilation mask at night. In its late update Tuesday, the Vatican said Francis had no further respiratory episodes during a day spent praying, resting and undergoing respiratory physiotherapy. Doctors said that they would put the noninvasive mechanical ventilation mask back on him while he sleeps, but that during the day he was only using high flows of supplemental oxygen. Doctors said his prognosis remains guarded, meaning he is not out of danger.

The Vatican says that Pope Francis has suffered two new episodes of acute respiratory crises and has been put back on noninvasive mechanical ventilation. Doctors extracted "copious" amounts of mucus from his lungs in another setback in what has become a more than two-week battle to overcome a complex respiratory infection and pneumonia. In a late update Monday, the Vatican said the episodes were caused by a "significant accumulation" of mucus in his lungs and bronchial spasms. "Two bronchoscopies were performed with the need for aspiration of copious secretions," the Vatican said. Francis remained alert, oriented and cooperated with medical personnel. The prognosis remained guarded.

The Vatican says Pope Francis has shown further slight improvement as he battles double pneumonia, but doctors still say his prognosis is still guarded. A CT chest scan taken Tuesday evening showed the "normal evolution" of an infection as it is being treated. Blood tests have confirmed an improvement, according to the Vatican's late update. The slight kidney insufficiency detected a few days ago has receded, and Francis is continuing to receive respiratory physiotherapy. It was the first time the Vatican has said Francis was receiving physiotherapy to help him expel fluid from his lungs. Francis resumed work in the afternoon, after receiving the Eucharist in the morning.
