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.

Exposure to PM2.5 components is associated with respiratory diseases
Through continuous research on the relationship between risk factors and health, it has been found that air pollution, especially atmospheric particulate matter pollution, has become one of the main sources of global disease burden. From 1990 to 2022, the concentration of atmospheric particulate matter pollution has increased by more than ...read more
