A 74-yr-old woman presented with dyspnea, fatigue, and abdominal pain. Central laboratory analysis showed a white blood cell count of 664,000/mm3 and hematocrit of 11.5%. Imaging revealed a large, solid, retroperitoneal mass with hemorrhagic conversion that was uneventfully treated with arterial embolization. However, her arterial blood gases (ABG) in the operating room and postoperatively while intubated consistently showed hypoxemia with an arterial oxygen tension (PaO2) of 37-60 mmHg. Surprisingly, this situation occurred despite a pulse oximetry saturation of 98-100%. In addition, the PaO2 did not increase despite the administration of 100% oxygen and multiple ventilation adjustments. …
