POPE Francis has suffered an “isolated” breathing crisis while receiving treatment in hospital, Vatican sources revealed.

The 88-year-old pontiff experienced a sudden deterioration in his condition following a bout of bronchospasm, which triggered vomiting and further complications.

Vatican insiders detailed the alarming episode, stating: “This afternoon, after a morning spent alternating respiratory physiotherapy with prayer in the chapel, the Holy Father presented an isolated attack of bronchospasm which, however, led to an episode of vomiting with inhalation and a sudden worsening of his respiratory condition.”

Medical staff acted swiftly, clearing his airways and initiating non-invasive mechanical ventilation.

“The Holy Father was promptly aspirated and started on non-invasive mechanical ventilation, with a good response on gas exchange,” the sources confirmed.

Despite the scare, Pope Francis remained alert throughout the ordeal, according to the Vatican.

“The Holy Father always remained vigilant and oriented, collaborating in the therapeutic maneuvers.”

While his condition appears to have stabilised, the prognosis remains uncertain.

“The prognosis therefore remains reserved. In the morning he received the Eucharist.”

This latest health setback follows a series of hospital visits in recent months, raising concerns over the Pope’s ability to continue his demanding schedule.

The Vatican has yet to issue an official statement on whether this will affect his upcoming engagements.

The Pope was admitted on February 14 after struggling with breathing difficulties, later being diagnosed with pneumonia in both lungs.

Despite growing speculation about a possible resignation, the Vatican has firmly denied that Francis is considering stepping down.

Parolin himself dismissed the rumours, telling Corriere della Sera that “such speculation is useless” and that what matters now is the Pope’s health.

Francis, who has led the Catholic Church since 2013, has a history of lung problems, having had part of one lung removed due to pleurisy as a young man.

His pre-existing condition makes pneumonia particularly dangerous for him, and doctors say his condition remains “touch-and-go.”

The Pope’s illness has prompted an outpouring of support from the faithful.

Thousands have been gathering in St. Peter’s Square to pray for his recovery, while visitors at Rome’s Gemelli Hospital — where he is being treated — paused to offer prayers at the statue of St. John Paul II outside the main entrance.
