Jun 24, 2024 · Pulse oximeters are a quick and painless way to check your levels. Oxygen levels between 95% and 100% are optimal for most people. If you track your oxygen saturation levels at home, connect with your health care provider to ensure you use the device correctly to get the most accurate readings.
- An over-the-counter pulse oximeter can cost anywhere from $25 to $100. Look for FDA-approved devices.
- How often you test may vary depending on your health condition. Ask your health care provider how often to check your levels.
- Healthy oxygen levels are approximately 95% to 100%. If your reading is consistently below 95%, seek medical attention.
- Yes. Recent research found racial bias in oximeter readings. Studies show that people with darker skin tones sometimes get less accurate readings t...
Apr 29, 2024 · A pulse oximeter is a simple and helpful way to monitor oxygen delivery, or oxygen saturation, within the body. Knowing your oxygen levels and heart rate can help you decide when to call the doctor or emergency services if a condition worsens. How does a pulse oximeter work?

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.

Jun 13, 2024 · Healthcare providers typically check blood oxygen levels through sensors called pulse oximeters placed on the skin. These sensors can work almost anywhere, but a sensor placed on your finger is the most common method.
Sep 13, 2024 · Pulse oximetry is a quick, noninvasive test that measures the oxygen saturation levels in the blood, using a device called a pulse oximeter. It helps monitor how well oxygen is being delivered throughout the body. It is commonly used in hospitals, healthcare provider offices, and at home.
Feb 18, 2022 · There are two main ways to measure or test blood oxygen levels: through a blood draw test and through pulse oximetry (using an oximeter). A blood draw test provides much more information about your oxygen levels than an oximeter does.

Sep 8, 2022 · Pulse oximetry is a simple, cheap, and noninvasive procedure used to measure the level of oxygen (or oxygen saturation) in the blood. Oxygen saturation should always be above 95 percent. However, oxygen saturation may be lower if you have a respiratory disease or congenital heart disease.
