Key Takeaways

  • Finger pulse oximeters measure the amount of oxygen in the bloodstream. Most models will also display your heart rate, pulse strength, and other vitals. 
  • These devices gained popularity during the COVID-19 pandemic. However, they can— and should be—used by most individuals with lung disease, congestive heart failure, asthma, sleep apnea, and other conditions. 
  • A low oxygen level may indicate hypoxemia, a potentially life-threatening condition that requires emergency care. Pulse oximeters can also detect and measure high oxygen levels in those using supplemental oxygen. 
  • FDA-approved pulse oximeters are generally more accurate than their over-the-counter (OTC) counterparts. But even so, some of the best OTC oximeters often work just as well as a medical-grade device.

While the COVID-19 pandemic made more people aware of the use and accessibility of pulse oximeters, if you’ve been in a hospital before you might have had one clipped to your finger before to measure your oxygen levels. Having low oxygen levels in the blood can be a sign of a number of disorders, including congestive heart failure or pneumonia. That’s why we’ve researched and reviewed nine of the best pulse oximeters, so if you’re experiencing symptoms of low blood oxygen, or have already been diagnosed with a condition that requires one, you can find the right one.

Having low blood oxygen levels is a health condition called hypoxemia, and it can be acute or chronic, depending on its underlying cause. According to the Cleveland Clinic, symptoms can range from mild to severe and may include headaches, wheezing, breathing problems, heart palpitations, and coughing. Some people may also notice a bluish discoloration of the skin and fingernails, which is due to a lack of oxygen in the blood. 

Individuals with congenital heart defects, anemia, lung disease, and other conditions are more likely to experience this problem. In such cases, it makes sense to use a pulse oximeter to check if there’s enough oxygen in your blood. This small fingertip device measures oxygen saturation (SpO2), giving you more control over your health. For example, people with asthma can use pulse oximeters to track their SpO2 levels throughout the day and request medical help if necessary (e.g., SpO2 levels below 92%). 

Prescription oximeters are regulated by the U.S. Food and Drug Administration (FDA) and undergo extensive testing. These devices have low error rates (2%–3%) and can measure oxygen saturation levels of 70%–100%. Over-the-counter (OTC) oximeters don’t require FDA approval, but this doesn’t mean they are less accurate. 

Both prescription and OTC pulse oximeters measure blood oxygen levels, pulse strength, and heart rate. If your SpO2 levels are constantly below normal values, your doctor may prescribe a portable oxygen concentrator to increase the amount of oxygen in your blood. 

Why Would You Need a Pulse Oximeter? 

Pulse oximeters may come in handy for those with asthma, heart failure, pneumonia, chronic obstructive pulmonary disease (COPD), and other conditions that can affect blood oxygen levels. In some cases, they may also be recommended for individuals who’ve had a heart attack and those diagnosed with lung cancer, according to the University of Rochester. 

“Pulse oximeters are especially useful for anyone who has a lung condition that could affect their lungs’ ability to bring in enough oxygen,” said Dr. David Culpepper, an internal medicine physician and the Clinical Director of LifeMD. “Two examples would be emphysema or asthma. Such patients can use the pulse oximeter to see if they are getting enough oxygen. An asthmatic patient could use the data from the oximeter to determine if they need to use their inhaler.” 

These devices are also useful for COVID-19 patients, athletes, and individuals traveling to high altitudes, noted the American Thoracic Society. For example, physically active older adults may use pulse oximeters during or after training to ensure their lungs can keep up with the demands of exercise.

Best Pulse Oximeters for Home Use

A pulse oximeter cannot replace medical advice, but it can be a valuable tool for those with lung or heart conditions. Ideally, you want to choose one that’s highly accurate and comes with handy features, such as a bright display, smartphone compatibility, and real-time updates. The device should also be easy to use and fit a variety of finger sizes. Its design, materials, and battery life matter too. 

With that in mind, let’s take a closer look at some of the best pulse oximeters on the market and how to pick the right one for you. The models listed below—including those approved by the FDA—are available without a prescription.

Why We Like It: This FDA-approved pulse oximeter weighs only 0.2 pounds and features a compact design and highly sensitive nanosensors for quick, accurate results. 

Oxiline Pulse 7 Pro can measure blood oxygen levels, heart rate, and perfusion index (PI), or the ratio of pulsatile blood flow to non-pulsing blood, in seven seconds or less. The results are displayed in red digits on a large, bright screen for easy readability. All you need to do is press the power button and attach the oximeter to your finger. The device will turn off automatically after each use. 

What makes the Pulse 7 Pro stand out is its high accuracy and intuitive interface.

“When you are on oxygen, it is sometimes hard to recognize if you need more. I have been diagnosed with mild COPD, so am not on oxygen continually. I needed help recognizing when I needed to have more. This handy little gadget can tell me within 2+ or 2- my oxygen level. Easy to read, lit-up display. Almost like being in the doctor’s office.”

“At first I was really skeptical about the ‘invisible screen’ design of this considering almost every other PulseOx unit out there has a tiny matrix display. I thought this would be more limited. How wrong I was! I actually now *prefer* this over my other units! Much larger display, much brighter and easier to read (no glasses needed), and incredibly fast at reading too! It beats some other units that cost a lot more. Add in that it’s not only wireless so it records the data to your phone, but it just looks freaking cool too and you have an absolute winner. Couldn’t be happier, and you won’t be either.”

How to Use a Finger Pulse Oximeter 

Pulse oximeters work by sending wavelengths of infrared light through your finger, toe, or earlobe to a photodetector. This allows the device to measure the amount of oxygen in your blood. The test is quick and painless and can be performed anytime, anywhere. 

If you have never used a finger pulse oximeter, take these steps to get started:

  • Wash your hands with warm water and soap
  • Turn on the device 
  • Remove nail polish from the finger you want to use
  • Slip your index or middle finger inside
  • Keep your hand still and below chest level
  • Wait until the numbers on the screen stop changing and then check your reading

Generally, it’s recommended to place the device on the finger next to your thumb on either hand. However, one study found that SpO2 measurements are most accurate for the right middle finger or thumb. If you use a quality device, you should get similar values—regardless of which finger is scanned. 

Like most electronic devices, finger pulse oximeters have their limitations. For example, the FDA states that people with thick or dark skin may get inaccurate readings. The same can happen if you’re a cigarette smoker or have circulatory problems. Also, note that nail polish and artificial nails can block the infrared light emitted by the device, affecting your results. 

Tattoos may influence the accuracy of your readings, too, but more research is needed in this area. If you have a tattoo on your index or middle finger, place the device on other fingers or choose a model with ear or toe sensors. 

Our Verdict

Finger pulse oximeters come in all shapes and sizes, making it easy to find the right one for you or your patients. Some are more suitable for sports enthusiasts, while others appeal to children or older adults. If you want a device that works with your smartphone, the iHealth Air Wireless Pulse Oximeter can be a good choice. Other models, such as the fingertip pulse oximeter from Wellue, can automatically save your data without the need for a smartphone or mobile app. 

The Oxiline Pulse 7 Pro is our favorite pick because of its ease of use, large bright screen, long battery life, and high accuracy, but other models work just as well. It all comes down to what you’re looking for. The Oxiline Pulse MD Pro, for example, is best for continuous monitoring, but you may want to purchase a more basic model, like the Walgreens Fingertip Pulse Oximeter. Research your options, check out our reviews, and choose a device that meets your individual needs.
