She is twin B of a monochorionic, diamniotic twin gestation, born via induced vaginal delivery for acute-onset oligohydramnios in the setting of intrauterine growth restriction. The maternal medical history is significant for depression, idiopathic hypothyroidism (treated with levothyroxine during pregnancy), and obesity. Maternal serologies were negative. Results of routine prenatal echocardiography were normal. After routine resuscitation, the infant receives respiratory support via humidified high-flow oxygen via nasal cannula and umbilical venous catheterization (UVC) for parenteral nutrition. The infant is weaned to room air and continued on a combination of parenteral and enteral nutrition going into the third day of life. At 50 hours after birth, the patient develops acute respiratory distress. The physical examination is remarkable for signs of respiratory distress, including tachypnea, hypoxemia, nasal flaring, and decreased breath sounds on auscultation (specifically in the right lower lung fields). She has distant heart sounds, no murmur, normal pulses and capillary refill, and a soft, nondistended abdomen. Laboratory evaluation includes a white blood cell count of 7,400×/μL (7.4×109/L), a hematocrit value of 53%, a platelet count of 215×103/μL (215×109/L), a capillary blood gas sample (pH of 7.18, partial pressure of carbon dioxide of 64 mm Hg, partial pressure of oxygen of 32 mm Hg, bicarbonate of 22 mEq/L [22 mmol/L], base deficit of 7.3 mEq/L [7.3 mmol/L]), and a C-reactive protein level less than 0.3 mg/L (
