Factors to Consider When Buying the Pulse Oximeter

Accuracy and ReliabilityAccuracy and Reliability

The surepior pulse oximeter can do much more than take a patient’s blood oxygen levels, but its primary purpose is to reliably take accurate SpO2 measurements. Therefore, the key to shopping for a good pulse oximeter is finding a model that consistently produces accurate results.

While most oximeters use similar measurement mechanisms, where and how they were manufactured plays a large role in their accuracy.

Most oximeters are accurate within three percent and are capable of taking readings in just a few seconds. However, as you can see from the pulse oximeter reviews above, some are up to 99 percent accurate, so make sure to check these stats when perusing fingertip oximeter reviews.

Just remember, the accuracy of a pulse oximeter is often affected by movement. Even the best oximeter in the world will take an inaccurate reading if a patient’s hand is trembling and shaking.

FDA ApprovalFDA Approval

As a class II device, pulse oximeters must be approved by the FDA in order to be sold in the US. While many of today’s pulse oximeters are certified by the FDA, you can verify an oximeter’s certification by entering the manufacturer’s name in the publicly available FDA Medical Device Data Base. Check out our pulse oximeter reviews fda approved above.

Ease of UseEase of Use

When reading a finger pulse oximeter review, you should also keep your eye out for the device’s ease of use. As you know, fingertip pulse oximeters work by inserting a finger into a cavity with a sensor. To take a reading, you simply press a button. Although they are all easy to operate in this regard, some have larger displays and multiple ways of displaying data, making them easier to use than others.

Display Size & ReadabilityDisplay Size & Readability

As mentioned, display size and readability are important factors in an oximeter’s ease of use. In addition to being large in size, a display should have large enough numbers to be seen in a wide-variety of lighting conditions.

Battery LifeBattery Life

If you’re a nurse or respiratory therapist, chances are you’ll be using your new pulse oximeter several times a day, day after day. Therefore, you should choose a model with as long of a battery life as possible. Most oximeters powered by AAA batteries have a minimum battery life of 30 continuous hours of use. More expensive models with lithium batteries are often rechargeable, so this is a non-issue.

Sensor SizeSensor Size

Whether you work in pediatrics and find yourself in need of informative pediatric pulse oximeter reviews or a General Practitioner who helps treat patients of all sizes, it’s important for their fingers to comfortably fit in the oximeter’s sensor. Although this is usually not an issue, if you do happen to work in pediatrics you should definitely keep sensor size in mind.


Price isn’t exactly the most important consideration when shopping for a pulse oximeter, but it’s always a plus to find an accurate and reliable model for a reasonable price. Lucky for you, you don’t have to spend hundreds of dollars on a quality pulse oximeter as there are several surprisingly affordable options to choose from. Just remember, however, that like most things in life, you often get what you pay for. So, make sure not to sacrifice features and performance in the name of getting a good deal.
