Pope Francis has reportedly increased his physical therapy, despite his outlook remaining "guarded," according to the Vatican. He apparently underwent high-flow oxygen therapy during the day and non-invasive ventilation at night.

Pope Francis "rested well during the night and woke up shortly after 8:00 a.m.," according to the Holy See Press Office on Wednesday morning. The pope, 88, is receiving treatment for bilateral pneumonia at Rome's Gemelli Hospital.
