Effect of Extreme Leukocytosis on Arterial Oxygen Tension / 대한마취과학회지

Arterial blood gas analysis has become an integral part of the clinical evaluation of the patient with known or suspected pulmonary disease. However, when the results of the measurements show arterial hypoxemia which is out of proportion to the clinical and X-ray evidence of lung disease, we may consider potential errors in measurement involving the blood gas analyzer or methods of blood sample storage. We experienced spurious hypoxemia in a patient with extreme leukocytosis (220.0 X 10(3)/mm3) secondary to leukemia. The degree of PaO2 decay was blunted by placing the blood on ice.
