In turn, these capillaries send oxygen-rich blood to the heart, which then pumps it through arteries to the rest of the body. Our organs need a constant supply of oxygen to work properly. When the capacity of the lungs to transport oxygen into the blood is impaired, blood oxygen saturation declines, potentially putting our organs in danger.
A pulse oximeter can quickly detect this drop in oxygen saturation, alerting people of the need for medical intervention. More recently, the spread of COVID , which can cause significant drops in blood oxygen saturation, has spurred a surge in the popularity of at-home pulse oximeters. Some people who are worried they may have—or fear contracting—COVID, have purchased pulse oximeters with the aim of monitoring their blood oxygen levels. Thus, persistently low readings should be discussed with a doctor.
A small, electronic device called a pulse oximeter is clipped onto a part of the body, usually a fingertip. The device emits light that passes through the fingernail, skin, tissue, and blood. On the other side of the finger, a sensor detects and measures the amount of light that passes through the finger without getting absorbed by the tissue and blood.

Takeaway Pulse oximetry is a noninvasive test that measures the oxygen saturation level of your blood. Purpose and uses. How to take a reading. Pulse oximetry is a test used to measure the oxygen level oxygen saturation of the blood. It is an easy, painless measure of how well oxygen is being sent to parts of your body furthest from your heart, such as the arms and legs. A clip-like device called a probe is placed on a body part, such as a finger or ear lobe. The probe uses light to measure how much oxygen is in the blood.
This information helps the healthcare provider decide if a person needs extra oxygen. Pulse oximetry may be used to see if there is enough oxygen in the blood. This information is needed in many kinds of situations. It may be used:. Pulse oximetry is also used to check the health of a person with any condition that affects blood oxygen levels, such as:. Heart attack. Heart failure.
