Pope Francis remains in critical condition but has not suffered any additional respiratory crises, the Vatican announced on Sunday. The update comes a day after the 88-year-old pontiff was reported to be in a serious state following a week-long hospitalization for a lung infection.

According to Vatican officials, Francis had a “quiet night” and “rested well,” adding that he remains conscious and is undergoing further medical tests. The pope is still receiving supplemental oxygen, and recent evaluations have indicated “initial, mild” kidney failure, though doctors have assured that the situation is stable and under control.

Despite ongoing concerns, medical staff described Francis as alert and “well-oriented.” However, the Vatican maintained that his “prognosis remains reserved,” citing the complexity of his condition and the need to monitor his response to ongoing treatments.

Additionally, the pope has undergone blood transfusions due to anemia-related symptoms, and his doctors anticipate he will remain in the hospital for at least another week.

While the Vatican previously stated on Friday that his condition was not life-threatening, medical experts have cautioned that he is “not out of danger.”
