The Holy See Press Office issued the following medical update on Pope Francis' health on Tuesday evening. The Pope is receiving treatment for bilateral pneumonia at Rome's Gemelli Hospital.

"The clinical condition of the Holy Father remained stable today. He did not experience episodes of respiratory failure or bronchospasm.

"The Pope did not run a fever, and he remained alert, cooperative with therapies, and oriented.

"This morning, he transitioned to high-flow oxygen therapy and underwent respiratory physiotherapy.

"As scheduled, tonight he will resume non-invasive mechanical ventilation until tomorrow morning. The prognosis remains guarded.

"During the day, he alternated between spending time in prayer and at rest, and this morning he received the Eucharist."

Pope Francis' overall clinical condition remains stable, including heart, kidney, and blood values.

The frequency of bronchospasms is not unexpected in the context of pneumonia like that affecting the Pope. However, his health situation remains complex.
