56 year old female with a history of morbid obesity and obstructive sleep apnea, presented with a progressively worsening shortness of breath. Arterial blood gas showed evidence of hypoventilation and CO2 retention. Eventually, the patient had to be intubated for respiratory failure. Echocardiography revealed evidence of right ventricular failure and pulmonary hypertension due to chronic hypoventilation and hypoxemia. The Chest XR above demonstrates low lung volumes and a significant amount of subcutaneous tissue.
