Pope Francis, 88, is in critical condition due to double pneumonia and a severe lung infection. While receiving high oxygen flows and blood transfusions, doctors fear the onset of sepsis, which could further complicate his condition given his advanced age and respiratory issues.

Pope Francis remains in “critical” but stable condition, Vatican spokesperson Matteo Bruni said on Tuesday, adding that the 88-year-old did not have any “acute respiratory episodes” and had a scheduled CT scan to monitor his pneumonia.
