Jun 13, 2024 · A normal range for your blood oxygen level is between 92% and 100%. SpO2 readings can fluctuate based on activity, overall health, and other factors. Your body relies on a coordinated effort between your heart, lungs, and circulatory system to maintain a healthy blood oxygen level. Without an adequate amount of oxygen in your blood, you can ...
Sep 13, 2024 · Most people have a normal resting pulse oximetry reading for oxygen saturation (SpO2) between 95% and 100%. This shows that your blood has an appropriate amount of oxygen. People at higher altitudes may have slightly lower readings. If your oxygen saturation level drops below 95%, it may suggest a potential issue with your lung or heart function.
A pulse oximeter is a device that checks to see how much oxygen your blood is carrying. Usually a small clip is put on the end of your finger. (Sometimes it's put on your toe or earlobe.) The device shines a light beam through the skin. It estimates your oxygen level by measuring the percentage of your blood that's carrying oxygen.

Pulse oximeters clip onto a fingertip and send beams of red and infrared light through tissues such as the nail, skin, and blood. The amount of oxygen in the tissue—called oxygen saturation—affects how well it absorbs light. The clip’s sensor measures how much light passes through without first getting absorbed by the tissue. Oxygen saturation leve...
The U.S. Food and Drug Administration (FDA) currently statesthat there are two categories of pulse oximeters: those for prescription use and those that can be purchased over the counter. 1. Prescription oximetershave been vetted by the FDA and are available only with a prescription. These devices have undergone clinical testing to confirm their acc...
Read the manufacturer’s instructions before using a pulse oximeter at home. The intended use of your pulse oximeter should be available in the manufacturer’s instructions. Make sure your hand is warm and relaxed and is resting below your heart. Remove any fingernail polish or artificial nails on the finger being tested. Keep your body still. When t...
FDA recommends that people who use pulse oximeters at home pay attention to other signs or symptoms of low oxygen levels and whether those symptoms change over time. These may include: 1. Bluish coloring in the face, lips, or nails 2. Shortness of breath, difficulty breathing, or a cough that gets worse 3. Restlessness and discomfort 4. Chest pain ...
Any of these factors can affect pulse oximeter readings: 1. Fingernail polish or artificial nails 2. Skin temperature: A skin temperature of about 91.4°F is recommended 3. Altitude 4. Intravenous dyes: These are used to color blood serum for surgical or diagnostic purposes and can affect light absorption 5. Poor circulation 6. Skin thickness 7. Tob...
Recent studies have suggested that prescription pulse oximeters may be less accurate for people with darker skin tones. Melanin (the natural pigment that gives skin, eyes, and hair their color) absorbs the red and infrared light from pulse oximeters, and the amount of melanin you have can change how much light is absorbed. People with darker skin t...
Researchers need more evidence to determine whether the racial disparities found in these case studies were specific to those hospitals or if this is a widespread problem. Better data science and collection of information from medical devices can help track patterns that lead to health disparities. “With the advancement in data mining tools and cap...
Pulse oximeters may be prescribed by a doctor or purchased over the counter. The FDA recommends knowing the difference so that patients use pulse oximeters safely. Prescription oximeters are reviewed by the FDA; available by prescription only; have undergone clinical testing; and are used for medical purposes. Over-the-counter oximeters are availab...
An arterial blood gas test is more invasive and painful than using a pulse oximeter, but it’s a more accurate way to measure oxygen and carbon dioxide in your blood as well as the balance of acids and bases. Having too much or too little acid in your blood can be harmful.
New pulse oximeter design wins NIBIB 2022 DEBUT Challenge
A team from Johns Hopkins University in Baltimore, Maryland, won first place in the 2022 Design by Biomedical Undergraduate Teams (DEBUT) Challenge for their EquinOx pulse oximeter. The EquinOx is better able to estimate blood oxygen saturation levels using its new hardware that measures both skin tone and the device’s raw data. The $20,000 prize includes coaching to make the device commercially available. Read more about the DEBUT Challenge.
Technology Development to Reduce Health Disparities
This research project grant from NIBIB and the National Institute on Minority Health and Health Disparities (NIMHD) supports medical technologies aimed at reducing disparities in health care access and health outcomes. NIBIB and NIMHD seek technologies that are effective, affordable, culturally acceptable, and deliverable. Learn more about this funding opportunity.
NIH Minority Health and Health Disparities Strategic Plan 2021–2025
This five-year plan sets goals for NIH to address health disparities among racial and ethnic minority groups in medical research and clinical care. These goals include testing common health indicators to measure the scale of health disparities across different diseases, conditions, and populations. Another goal is to include more minorities and members of health disparity populations in big data sets, clinical research, and future big science initiatives. Read more about the Strategic Plan.
