Pope Francis passed a calm day in hospital Tuesday with no repeat of the previous day's respiratory crises, but the 88-year-old will wear an oxygen mask overnight, the Vatican said. The head of the Catholic Church has been in Rome's Gemelli hospital since February 14 for treatment of double pneumonia in both lungs.

Pope Francis was in stable condition Tuesday and breathing with just the help of supplemental oxygen after respiratory crises a day earlier, but will resume using a ventilation mask at night, the Vatican said.
