Pope Francis had two bouts of acute respiratory insufficiency, the Vatican said in a statement on Monday night.
The Holy See Press Office clarified that the sickness was caused by a massive deposit of endobronchial mucus, which caused bronchospasms.
The Holy Father underwent two bronchoscopies to remove gigantic secretions.
The news also indicated that non-invasive mechanical ventilation was restarted earlier in the day.
“The Holy Father remained alert, oriented, and cooperative at all times,” the Press Office confirmed, while also stating that his prognosis remains guarded.
Acute respiratory insufficiency occurs when an individual’s oxygen levels do not reach the required level.
Earlier on Monday, Pope Francis announced that he had chosen “Migrants: Missionaries of Hope” as the theme for the 111th World Day of Migrants and Refugees.
“Many migrants and refugees bear witness to hope through their trust in God,” read a post on the Pontiff’s official X account.
This year’s World Day of Migrants and Refugees will take place in October during the Jubilee.
