Case Report
Correlation of Pseudohypoxemia and Leukocytosis in Chronic Lymphocytic Leukemia
Abstract
AbstractPseudohypoxemia has been reported in leukemic patients with extreme leukocytosis, and it is characterized by a low oxygen saturation on arterial blood gas analysis despite normal saturation on pulse oximetry. We report the case of a 51-year-old man with chronic lymphocytic leukemia and an elevated white blood cell (WBC) count after splenectomy; his progressive postoperative pseudohypoxiemia gradually improved as the leukocytosis was lowered by chemotherapy. We believe this is the first report to show a statistically significant correlation between the WBC count and the degree of pseudohypoxemia in a patient with leukemia.This content is limited to qualifying members.
