In May 2022, she was admitted and treated successfully for bronchopneumonia exacerbating obesity-hypoventilation syndrome with acute respiratory acidosis (Fig. 1 a, Fig. 2 a). Chest radiography showed atelectatic bands in both lower lung zones (Fig. 1 b). Clinical, radiological, and laboratory improvements were observed (oxygen therapy was discontinued, she was able to go about her daily activities, subsequent chest radiography showed resolved bilateral atelectatic bands with normal lung volumes (Fig. 1 c), and subsequent arterial blood gas analysis was normal except that daytime Paco2 was 47 mmHg).
