Finger Pulse Oximeter

Description

Pulse oximeter is a noninvasive and painless test that measures your oxygen saturation level, or the oxygen levels in your blood.
It is a small, clip-like device that attaches to a body part, like toes or an earlobe. It’s most commonly put on a finger, and it’s often used in a critical care setting like emergency rooms or hospitals. Some doctors, such as pulmonologists, may use it in office.
