The Vatican says Pope Francis is in critical condition after he suffered a long asthmatic respiratory crisis that required high flows of oxygen.

Doctors on Friday said the 88-year-old Francis is "not out of danger" ​and that the main threat facing him would be the onset of sepsis.

Pope Francis experienced “an asthmatic respiratory crisis of prolonged magnitude, which also required the use of oxygen at high flows” Feb. 22, said the daily medical bulletin released by the Vatican.
