A pulse oximeter is a device that can measure the amount of oxygen in someone’s blood. It has two sensors, one on each finger.
The device takes the person’s pulse and calculates how much oxygen is in their blood. The patient must not be wearing any rings or watches to use a pulse oximeter.

The tool can be used to detect low oxygen levels and help prevent them from becoming serious enough to cause death.
A pulse oximeter is a type of medical device that measures oxygen levels in the blood. It is often used to check for signs of illness, such as heart disease or stroke.
How does a pulse oximeter work?
A pulse oximeter measures the amount of oxygen in the blood by measuring the amount of light that is reflected off the red blood cells. The higher the level of oxygen in the blood, the more light is reflected and the higher the reading on the oximeter.
Pulse oximeters can help doctors diagnose diseases and monitor patients’ health. They can also be used to determine if someone has had a stroke or heart attack. Pulse oximeters are often used during surgery to determine if a person has lost too much blood.
In addition, pulse oximeters can be used to monitor athletes and people who are working out in an environment with high levels of oxygen (for example, anaerobic exercise).
