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.

摘要

动脉血气分析显示存在低氧血症的极度白细胞增多或血小板增多患者，使用脉搏血氧饱和度仪测量时可能显示氧饱和度正常。对于这一现象，最常提及的解释是血气样本在分析前血液中的氧被消耗。然而，其他人对低氧血症是假像这一前提提出了质疑。我们描述了一名患有极度白细胞增多和低氧血症的患者，通过连续血气分析证实其存在正常氧合。
