title: Confirmation of spurious hypoxemia using continuous blood gas analysis in a patient with chronic myelogenous leukemia.
abstract: Patients with extreme leukocytosis or thrombocytosis who have hypoxemia on arterial blood gas analysis may demonstrate normal oxygen saturation using pulse oximetry. The most commonly invoked explanation for this phenomenon is oxygen consumption in the blood gas sample prior to analysis. However, others have challenged the premise that the hypoxemia is spurious. We describe a patient with extreme leukocytosis and hypoxemia in whom normoxia was confirmed by continuous blood gas analysis.
