Pope Francis rested well overnight at Rome's Gemelli Hospital, according to the Holy See Press Office on Wednesday morning.

He has been receiving treatment for bilateral pneumonia since February 14, and he resumed non-invasive mechanical ventilation overnight, as his doctors had scheduled.

A Tuesday evening update noted that his clinical condition remained stable throughout the day.

"The Pope did not run a fever, and he remained alert, cooperative with therapies, and oriented," said the Press Office on Tuesday. "This morning, he transitioned to high-flow oxygen therapy and underwent respiratory physiotherapy."
