Pope Francis suffers acute respiratory failure episodes amid pneumonia battle

Pope Francis has experienced several acute respiratory crises in the past few weeks. The first crisis occurred on February 22, when he suffered a bronchospasm, similar to an asthma attack. He was admitted to Rome's Gemelli hospital, where doctors performed a bronchscopy to help clear his airways. The procedure was repeated on March 3, after Francis experienced two more breathing crises caused by a significant buildup of mucus in his lungs.
