After Pope Francis suffered a setback on Friday, doctors said it would take 24 to 48 hours to determine whether the crisis has worsened his condition. The Vatican said on Saturday that he was resting.

The Vatican reported Friday that he experienced sudden breathing problems that required “non-invasive mechanical ventilation” but that he remained “alert.”

Pope Francis, who has been hospitalised for two weeks battling double pneumonia, has spent another peaceful night and is now resting, the Vatican said on Friday. Francis, 88, was admitted to Rome's Gemelli hospital on February 14 with what was originally described as a bronchitis and was later revealed to have developed into something more serious.
