case_images: Oxygen and non-invasive ventilation were promptly weaned, and the patient was breathing without support on room air on the day of life 8 (31 + 4 weeks of PMA) (Figure 3). The respiratory status rapidly improved and six days later (37 + 6 weeks of PMA), the patient no longer needed supplemental oxygen (Figure 3).
