The Vatican said Monday that Pope Francis suffered two new episodes of “acute respiratory insufficiency,” with a prognosis that “remains guarded.” The pope’s condition is the result of “a significant accumulation of endobronchial mucus and consequent bronchospasm,” the Vatican said in a statement.

Pope Francis has suffered "two episodes of acute respiratory failure", the Vatican has announced. In the latest health update this evening, the pontiff underwent two bronchoscopies, with doctors adding his prognosis is "uncertain". Afternoon saw him back on “non-invasive mechanical ventilation.” He remained “alert, oriented and cooperative”.
