Pope Francis hospitalized with pneumonia, condition uncertain

Pope Francis, hospitalized with pneumonia since February 14, experienced two new breathing attacks on Monday requiring separate bronchoscopies and resuming use of an oxygen mask.

The Vatican reported that the pontiff faced significant accumulation of endobronchial mucus and consequent bronchospasm during these episodes, causing concern about his condition.

Doctors continue to monitor Francis closely over the next 24 to 48 hours to assess any worsening of his health since Friday's breathing crisis.

Despite slight improvements noted last week, the pope remains alert but his prognosis is described as 'reserved', indicating uncertainty about recovery.

This hospital stay, now in its 18th day, is the longest of Pope Francis' nearly 12-year papacy and has raised speculation about possible resignation due to health concerns.
