A) Anterior-posterior chest radiograph two days after intensive care unit (ICU) admission showing bilateral lung opacities. B) Patient self-proning while wearing high-flow nasal cannula. C) Changes in oxygenation expressed as arterial partial pressure of oxygen to fractional concentration of inspired oxygen (P:F) ratio versus time from ICU admission. Initiation of self-proning sessions is indicated by red arrows. Following the last self-prone session, the P:F ratio failed to improve. The patient was subsequently un-proned, which did not improve oxygenation. The care team then realized that the patient had developed nasal congestion (due to blood clots) in his posterior nasal passages. Once these were cleared, his oxygenation once again improved, and he was discharged from the ICU to a dedicated COVID-19 ward.
