An Unusual Cause of Low Oxygen Saturation in the Operating Room

Author(s): Joseph Varon, Pilar Acosta, Ross Reul.

Abstract:

Pulse oximetry is commonly used in clinical practice as an indirect monitor of blood oxygen saturation. There are many factors, however, that can interfere with accurate readings. We present a case of a woman with metastatic thyroid cancer that had a sudden drop in her pulse oximetry during bronchoscopy and that eventually was found to have an uncommon cause for a misleading persistently low oxygen saturation.
