Pope Francis has suffered an “isolated breathing crisis” which caused him to vomit, provoking a “sudden worsening” of his respiratory condition, the Vatican said.
The episode happened on Friday afternoon after the pontiff, 88, spent the morning alternating “respiratory training” with prayer in the chapel at Rome’s Gemelli hospital, where he has been battling pneumonia for two weeks.
The Vatican said in its evening update that the pope inhaled the vomit, leading to the “sudden worsening” of his respiratory condition.
He was then administered “non-invasive mechanical ventilation” to help him to breathe, which had “a good response”, the Vatican added.
Francis remained “alert and well-oriented” and is continuing his treatments. His doctors’ prognosis remains guarded.
A Vatican official said the breathing crisis on Friday did not last for long and that his doctors were expected to need 24-48 hours to assess how the event would affect his clinical condition.
The episode came after three days in which the pontiff’s health had shown “slight” improvements, meaning his situation was no longer considered to be critical.
On Wednesday, a CT scan of the pontiff’s chest “showed a normal evolution” of the inflammation in his lungs, while the “mild kidney insufficiency”, which was diagnosed on Sunday, had resolved.
It is unclear how long he will remain in hospital. The Vatican said earlier on Friday that Francis would not be leading the church service on 5 March to mark the beginning of Lent.
Francis was admitted to hospital on 14 February and was subsequently diagnosed with a respiratory tract infection and pneumonia in both lungs.
He is prone to lung infections because he developed pleurisy as a young adult and had part of one lung removed while he was training to be a priest in his native Argentina.
