Monitoring your health metrics at home can help you manage chronic conditions, decide on the effectiveness of a treatment plan, and catch early warning signs of an illness. If you have COPD, asthma, sleep apnea, or another respiratory condition, a pulse oximeter can help measure your blood oxygen levels.

Blood oxygen or oxygen saturation levels, also called SpO₂, can indicate a concern with heart or lung health. When blood oxygen levels drop too low, you may have breathing difficulties or reduced blood flow. If these low levels or symptoms persist, you may need medical assistance.

When we reviewed the best pulse oximeters on the market, we chose Oxiline as the best overall, as we like the brand’s ease-of-use, customer-friendly policies, and range of features. Oxiline offers four different pulse oximeters, allowing you to find an option that fits your preferences and budget.

In this Oxiline pulse oximeter review, we outline what makes each model unique, compare their features and pricing, and highlight what you should consider before purchasing your own.

Why we recommend Oxiline pulse oximeters

Oxiline’s home health devices have consistently topped our recommendation lists for their simple setup, clear displays, and convenience. We like that Oxiline offers users multiple options. Those seeking continuous monitoring, whether they’re asleep or awake, can choose the Pulse MD Pro. If you want to track your results and share them with your health care provider, you may want the XS Pro. For a straightforward, budget-friendly option, consider the 9S Pro or the 7S Pro.  

Oxiline’s line of pulse oximeters aims to provide:

• Straightforward, one-button operation
• Clear, bold, bright, and user-friendly display

Understanding the Oxiline pulse oximeter models

Oxiline Pulse 7S Pro: The Basic Model

The Oxiline Pulse 7S Pro is Oxiline’s entry-level model, designed for daily use and fast results. This device features a no-slip grip and a rotating display to read results from any angle. These thoughtful details make the Oxiline 7S Pro a good choice for people new to monitoring their SpO₂ at home.

• Type of pulse oximeter: Digital, fingertip

• What it measures: SpO₂, BPM

Pulse 7S Pro features

• Battery type: Disposable (AAA)
• Battery life: 24 hours of continual operation
• Bluetooth compatible:  No

Pros and cons

Pros

• Beginner-friendly, straightforward interface
• Comfortable, no-slip grip
• Clear and accurate readings

Cons

• No app
• Long-term results must be tracked manually
• No additional health measurements

What’s different about the Pulse 7S Pro 

The Pulse7S Pro is the most basic of Oxiline’s models, tracking SpO₂ and BPM on a mono-colored display. Like all of the oximeters, you clip the 7S Pro onto your fingertip and wait for a reading. 7S Pro readings usually take under 10 seconds (the other models take 4-7 seconds). 

Like the other models, the 7S Pro has a rotational display, which makes it easier to read the results from any angle. The 7S Pro’s 1” display uses LED technology for bright, clear results.

At $59, the Pulse 7S Pro is Oxiline’s most affordable option (the next model up is the 9S Pro at $89). But as you’d expect at this price, the 7S is also the most stripped down. Unlike other models, the 7S Pro doesn’t come with an alarm for setting reminders. It’s also the only model without a plethysmograph, which helps measure the volume of liquid within your body and is helpful to monitor conditions like COPD. The 7S Pro doesn’t connect to an app, so if you need to track readings over time, you’ll have to do so manually.

For a straightforward SpO₂ reader without any bells or whistles, the Pulse 7S Pro is an affordable, entry-level option. We like this model because it’s budget-friendly, has a simple design, and is overall a user-friendly option.

Oxiline Pulse 9S Pro: The Most Popular Model

The Oxiline 9S Pro is the next step up from the 7S Pro, adding a multi-colored screen, alarm, and plethysmograph to the 7S Pro’s foundational features. It earned the best display in our guide to the best pulse oximeters because of its sharp and bright OLED screen. This feature shows each data reading in a distinct, bold color for easier interpretation.

• Type of pulse oximeter: Digital, fingertip

• What it measures: SpO₂, BPM, PI%, and pleth graph

Pulse 9S Pro features

• Battery type: Disposable (AAA)
• Battery life: 24 hours of continuous use
• Bluetooth compatible: No

Pros and cons

Pros

• Bright, clear display
• Multicolored results
• Small, sleek design

Cons

• No app for automating tracking
• Slightly smaller screen than the XS Pro

What’s different about the Pulse 9S Pro

The Pulse 9S Pro earned best display in our guide to the best pulse oximeters, and for good reason. The bright, bold display shows each piece of data in its own color. This simple feature makes it easier for users to know exactly what they’re looking at. It also sets the 9S Pro apart from the 7S Pro, which has a single-colored screen. 

You can complete a reading with the 9S Pro in under 7 seconds, which is slightly faster than the 7S Pro’s 10-second read time. And the 9S Pro adds perfusion index readings and a plethysmograph. These two pieces of data are important for people who might also have circulatory issues, like those with COPD.

When we tested the 9S Pro, we found that the Pulse 9S Pro excelled as a user-friendly pulse oximeter, making daily readings simple. “Overall this sleek and small design is easy to use and works well,” one tester said. “I like how the display shows my readings in different colors.”

Like the 7S, the 9S Pro doesn’t come with Bluetooth connectivity or an app. You’ll need to record your readings manually if you’re trying to track over time. But this is the only real difference between the 9S Pro and Oxiline’s next step up, the XS Pro. We think the 9S Pro would work well for someone who doesn’t need an app but wants more in-depth tracking metrics.

Oxiline Pulse XS Pro: The Data Tracking Model

The Oxiline Pulse XS Pro earned the top spot in our guide to the best pulse oximeters for its accurate, reliable readings and robust tracking app. It also features a fast result time of under four seconds, a large 1.5” Crystal OLED display, and the ability to export results to share with your health care provider. We found that these features make XS Pro a valuable tool for home health care management.

• Type of pulse oximeter: Digital, fingertip

• What it measures: SpO₂, BPM, PI%, and pleth graph

Pulse XS Pro features

• Battery type: Disposable (AAA)
• Battery life: 24 hours of continuous use
• Bluetooth compatible: Yes

Pros and cons

Pros

• Color-coded results
• Tracking app
• Reminder options

Cons

• Battery compartment is difficult to open
• Testers thought manual was overwhelming

What’s different about the Pulse XS Pro 

The Pulse XS Pro features Oxiline’s user-friendly app and advanced VTEC^TM AX technology, designed for more accurate readings. Like the 9S Pro, the XS Pro offers color-coded readings on a bright display (at 1.5”, the XS Pro’s screen is slightly bigger than the 9S Pro’s 1.2”). It also comes with the ability to set reminder alarms and can take accurate readings even if you’re on the move.

What really sets the Pulse XS Pro apart from the previous models is its app. The app syncs with your device’s readings in real time. It also stores your data for future reference and even displays them in shareable graphs and charts. This is especially helpful if your health care provider wants to see trends or changes in your health over time. Tracking your metrics and sharing them with your health care provider can help identify if your treatment plan is working or if your condition is getting better or worse.

 “The app is very intuitive and doesn't have a bunch of information, which I liked,” one tester said. “The user interface was clean, easy to navigate, and helpful to see my readings all logged without manually writing them down.”

The Pulse XS Pro can also sync with other apps, such as Apple Health or Android Health. You might find this beneficial if you already use those apps to help give you a better big-picture view of your overall health. If you’re interested in tracking and sharing your health data, we like the Pulse XS Pro’s features and user-friendly design.

Oxiline Pulse MD Pro: The Overnight Model

The Oxiline Pulse MD Pro is the brand’s only model that’s designed for long-term use. It can be used for continual monitoring during the day or as an overnight device while you sleep. Its extended cable makes it easier to wear in bed without getting tangled. The Pulse MD Pro is a great choice for people who need uninterrupted oxygen tracking, such as those recovering from surgery or with complex medical conditions.

Pulse MD Pro features

• Battery type: Rechargeable
• Battery life: 14 hours
• Bluetooth compatible:  Yes

Pros and cons

Pros

• Detachable 3-foot cable
• Continuous, uninterrupted readings
• Large display

Cons

• Most expensive on the list
• Short battery life

What’s different about the Pulse MD Pro 

Designed for comfort while monitoring continuously, the Pulse MD Pro is Oxiline’s only model that you can use to monitor your oxygen saturation and other key metrics overnight. Continuous readings can be beneficial for those with chronic conditions, like asthma, COPD, or sleep apnea. This feature can also be helpful when trying to decide the correct flow rate for supplemental oxygen.

Oxiline’s other pulse oximeters display their results right on the device that goes on the finger. The Pulse MD Pro separates the pulse oximeter and the display with a 3-foot detachable cable. Caregivers can review the results without disturbing the person receiving care. This separation also makes the device more comfortable to wear for longer periods of time. The MD Pro’s 3” display is also the largest available from Oxiline.

The Pulse MD Pro makes it much easier to track SpO₂ levels for many hours, since you can simply leave the oximeter on while in bed, watching TV, or reading. Oxiline’s other pulse oximeter devices all require you to push a button to take acute readings. But the Pulse MD Pro will take regular readings while you wear it. It then feeds its information to an app that creates shareable graphs and charts for your health care provider to review.

The Pulse MD Pro uses rechargeable batteries (all the other models use disposable batteries). It has a lifespan of about 14 hours before needing a new charge. Keep this charging schedule in mind if you plan to use this device continually.

Where to buy Oxiline pulse oximeters

You can buy Oxiline pulse oximeters directly from the company on their website. We recommend this option because it ensures the warranty applies to your device. Aftermarket or third-party purchases might not qualify.

If you choose to purchase your Oxiline pulse oximeters from a third-party retailer, you can find them on Amazon or at some medical retailers like Walgreens or CVS.

Who should use a pulse oximeter?

Pulse oximeters are designed for those who need to monitor their blood oxygen levels. If you have a chronic illness that can affect your breathing or participate in high-altitude sports like hiking, taking SpO₂ readings can help ensure your levels are within a safe range. 

People who use other home health monitoring devices, like blood pressure monitors, may also benefit from the additional information. You can read more in our guide to the best blood pressure monitors.

Some people who might need to use a pulse oximeter include:

• Those recovering from surgery
• Anyone with chronic conditions like asthma, COPD, or sleep apnea
• Caregivers responsible for monitoring health measurements
• Patients recovering from COVID-19
• Endurance athletes or people who participate in high-altitude sports

Pulse oximeters are also helpful for people who want to feel like they have more control over their health while at home. “I honestly feel a sense of relief to check my health as often as I can,” said one of our home health survey respondents.²

How to use a pulse oximeter

Taking a reading using a pulse oximeter is a straightforward process—just clip the sensor onto your fingertip and wait until the results appear on the screen. Pulse oximeters are painless. They use infrared and red light to measure the amount of oxygen stored in the tissue. The amount of oxygen affects how much light is absorbed.

Typically, you’ll want to see a blood oxygen reading between 95-100%.³ If you live at a higher altitude or have a chronic condition that affects your oxygen levels, you might see a lower, but still safe, percentage. Generally, anything below 92% warrants a call to your doctor, and anything under 88% means you need immediate medical care. But your specific ranges will be influenced by your personal health and where you live, so you should ask your doctor for a personalized range.

"The most important consideration is to measure medical data that is relevant to the patient’s diagnoses so that their medical practitioner can then use it to guide the care, adjust medications and modify treatment plans,” said Elisa Gil-Pires, MD, FACP, CMD, CPE, executive vice president of medical affairs, chief medical officer and medical director at Charles E. Smith Life Communities.

Factors that can affect pulse oximeter readings

Some factors can affect pulse oximeter readings and create inaccurate results. These include:

• Wearing nail polish
• Holding your hand is above your heart level
• Cold and circulation issues
• If you have calluses

Research has also shown that a person’s skin tone can affect the accuracy of a pulse oximeter.⁴ If you have darker skin tones or are Hispanic, Black, or Asian, your skin could possibly absorb different levels of infrared light, resulting in incorrect results. Make sure to bring up any concerns with your doctor.

Is an Oxiline pulse oximeter right for you?

Choosing the right pulse oximeter for you depends on your personal needs, diagnoses, and budget. We think Oxiline’s range of pulse oximeters offers a good range of features and tools, meeting a variety of budgets, so there’s a good chance one of them will fit what you need. 

Before purchasing a pulse oximeter, ask yourself these questions:

• What metrics do I need to track while at home?
