Pope Francis on assisted ventilation

The Vatican says Pope Francis suffered a coughing fit that resulted in him breathing in vomit, requiring non-invasive mechanical ventilation. The Vatican says he responded well, with a good level of gas exchange, and remained conscious and alert at all times. The episode, reported late Friday by the Vatican, resulted in doctors keeping his prognosis from a two-week battle with double pneumonia as guarded. It marked a setback after two days of increasingly upbeat reports about an improved condition. FOX 5's Teresa Priolo has the story.
