oximeter
Fingertip saturation monitor
An oximeter is a medical device that measures oxygen saturation in the blood.
The most common type, a pulse oximeter, clips onto a fingertip and uses light sensors to give a reading within seconds: The nurse checked my oxygen levels with a pulse oximeter.
Oximeters became household items during the COVID-19 pandemic for monitoring respiratory symptoms.
