Best Overall
Oxiline Pulse XS Pro
Clear, multicolored display and mobile app for tracking results
Many of us gain peace of mind by being well-informed. Digital health products designed to monitor your health at home can provide the information necessary to recognize the early warning signs of a growing health concern. These tools can be especially important when managing chronic conditions or recovering from illness. One important metric you can track at home is SpO₂, or blood oxygen saturation, which measures the percentage of hemoglobin in your blood that is saturated with oxygen.
If these oxygen levels drop too low, it can signal a serious problem, especially for people living with COPD, asthma, heart disease, or long-term effects of COVID-19. In these situations, a pulse oximeter provides a quick way to check oxygen levels and determine when it’s time to seek medical help. According to our survey of people who use home health monitoring devices, 57% of respondents reported buying one of these products at a doctor’s recommendation or to manage an existing condition.1
“I feel like I have a great tool to monitor my temperature and blood oxygen to monitor my sickness and let me know if I need to go to see an MD, PA, or NP. Empowered is a great word.”
—Respondent to our 2025 home health survey.1

In our research and testing, we looked at factors like:
- Warranty coverage
- Support responsiveness
- App connectivity
- Real-time monitoring
- Display readability
- Ease of setup
- Data tracking and sharing
We also considered each pulse oximeter's overall value, prioritizing devices that balance price, performance, and quality.
How do pulse oximeters work?
Pulse oximeters work by using red and infrared light to monitor the oxygen saturation of your blood. The device itself is small, painless, and clips onto the tip of your finger. The amount of oxygen in your blood affects how much of the light is absorbed. The pulse oximeter measures this amount, called the SpO₂, as well as your heartbeat. It then displays those results as a percentage. Most healthy people have a SpO of 95-100%. If you have a chronic illness like COPD, asthma, or live at a higher altitude, your SpO₂ may be lower.5
“For those with chronic illnesses, home monitoring can also provide peace of mind and transform health management from reactive to proactive. To note, these devices don’t replace medical care but they act as a complement to care to give patients and doctors clearer insights between visits, improving patient satisfaction and quality of life.”
– Michael Genovese, MD, Chief Medical Advisor at Ascendant New York
How to use a pulse oximeter
Using a pulse oximeter is typically straightforward—you clip the device to your fingertip and wait for it to display the results. But there are some key things to keep in mind to ensure the results are as accurate as possible. These include:
- Removing any jewelry or nail polish from your testing finger
- Keep your hand relaxed and below the level of your heart
- Keep the device on until it’s been able to fully read your SpO₂
Understanding your pulse oximeter readings
Understanding your pulse oximeter readings can provide you and your medical team with valuable insights into your health. A healthy person at sea level would expect to have a reading between 95–100%. If you live at a higher altitude or have a chronic illness like COPD, you may have a lower reading. But if your reading ever drops below 92%, you should call your health care provider. Readings this low can be a sign of serious conditions like hypoxia, in which not enough oxygen reaches your blood, or hypoxemia, in which not enough oxygen reaches your tissues. Readings below 88% may indicate the need for immediate medical care.6, 7
It’s important to remember that your specific SpO₂ range is influenced by where you live, especially the altitude, and what chronic illnesses you may have. Your doctor can provide you with a personalized target range for your SpO₂ readings.
How to choose a pulse oximeter
Choosing the right pulse oximeter depends on several factors, including your intended use and the reason you need it. For instance, if you need a device that tracks readings over time, consider the Oxiline XS Pro, which comes with an app that logs results. Or, if you have sleep apnea, consider the Wellue SleepU, which is designed for overnight wear. Your doctor can help you decide the most important features for your specific health goals.
Overall, we recommend choosing a pulse oximeter that’s either FDA 510(k) cleared or FDA-approved. This is because these labels indicate that the devices have been independently vetted and tested to ensure they provide accurate, consistent SpO₂ readings. Some over-the-counter brands aren’t tested at all, so you risk wasting money and time on a device that might not work as reliably.
“When managing chronic illness, home health devices empower patients to take a more active role in their care, whether those actions be tracking blood pressure, glucose levels, monitoring oxygen, or heart rhythms. Regular use of these tools can improve patient adherence to treatment, reduce emergency room visits, and help physicians adjust patient treatment.”
– Dr. Michael Genovese, Chief Medical Advisor at Ascendant New York
Key Features
When choosing a pulse oximeter for home use, you’ll want to consider two different types of features. First, ensure you choose a device that tracks the vital signs most relevant to your needs. Those can include:
- SpO₂ readings: Monitors the oxygen saturation in your blood. This gauges how effectively the body moves and uses oxygen. When your oxygen saturation is too low, your cells may lose the ability to perform their vital functions.
- Heart rate: Measures your heart rate in beats per minute. Your heart rate is a key indicator of your cardiovascular health. Abnormal heart rates can signal a potential heart condition, like an arrhythmia, where the heart beats irregularly.
- Perfusion index (PI): Measures the strength of your pulse (safe ranges are between .02% and 20%). The PI indicates the health of your blood circulation and can be a key tool in early detection of health concerns like blood clots or arterial disease.8
- Respiratory rate (RR) monitoring: Measures the number of breaths you take per minute. This is a vital sign that assesses overall health. A normal respiratory rate is 12–16 breaths per minute.9
You’ll also want to consider a pulse oximeter’s usability. These devices can have several key features that make them valuable for home health care management, including:
- Real-time sync: Uploads your results as they occur, usually to an app
- Data storage: Saves your results to an accessible app
- Export: Allows you to download and share your results, like with your doctor
- Display visibility: Bold, clear, easier-to-read numbers and results
- Finger sizes: Works for a variety of finger sizes
- One-button use: Makes it easier to take your own readings, especially with dexterity issues
How much do pulse oximeters cost?
The pulse oximeters on this list range in price from $23–$300. When choosing how much to pay for a pulse oximeter, consider what features are most important to you and whether you believe they are worth the cost. If you're looking for a robust app with easy data storage and sharing, it may be worth spending more on a pulse oximeter that comes with those features, such as the Masimo MightySat. Or if you just want something straightforward that doesn’t have too many bells or whistles, then you can opt for the Innovo. Typically, the more features a pulse oximeter has, the more expensive it will be.

Who should use a pulse oximeter?
People should use a pulse oximeter if they need to know their blood oxygen levels. If you have a chronic illness or participate in activities like high-altitude hiking, it’s important to have accurate SpO₂ level readings to make sure you’re in a healthy range. If the readings dip below a specific range and you’re experiencing symptoms of hypoexima, you may need to stop and rest. If those low readings and symptoms persist, you’ll know to seek out medical attention.
Some people who might need to use a pulse oximeter include:
- People with chronic illnesses like asthma or COPD
- People recovering from COVID-19
- Caregivers for older adults who are responsible for monitoring health measurements
- Endurance athletes or people participating in high-altitude sports
- People with sleep apnea
How skin color affects pulse oximeters
Recently, studies have shown that a pulse oximeter’s results can be affected by skin color: darker skin tones absorb more infrared light than lighter skin tones, potentially leading to less accurate readings for those with darker skin tones, such as those of Asian, Black, and Hispanic descent. Over time, this has resulted in a disparity of care for non-white populations.10 Consider any symptoms alongside the pulse oximeter readings, and to check with your health care provider if you have questions.
Other factors that can impact pulse oximeter readings
Some other factors that can impact pulse oximeter readings include:
- Wearing nail polish
- Cold hands
- Health conditions that cause impaired circulation
- Holding your hand above your heart while measuring
- Calluses or thicker skin on your testing finger
