Best Wearable Pulse Oximeters of 2020
When you think of a doctor you immediately have the image of a stethoscope in mind. While that is a very popular medical tool, there are others too that are widely used and very important. And among them, we have the pulse oximeter, a device that measures the amount of oxygenated blood in the body and gives important vital signs in many situations.
They are very beneficial for those suffering from conditions that affect blood oxygen levels, such as sleep apnea, asthma, lung cancer, heart failure, COPD (chronic obstructive pulmonary disease) and other medical issues. It basically gives an alert for when oxygen levels are too low and can also help doctors understand the daily fluctuations in order to give the proper treatment.
A pulse oximeter basically shows how well the heart is pumping oxygen, and in a hospital setting can determine if a heart attack or heart failure is taking place. While home oximeters are not as precise as those in hospitals, they can definitely give an indication if something serious is happening. And last but not least, pulse oximeters can also be used by sports enthusiasts, mountain climbers or aviators in order to perform their activities in safe conditions.

Best Wearable Pulse Oximeters
The Zacurate Pro Series 500DL Oximeter
This device offers accurate readings at an affordable price. It shows the blood-oxygen levels, the pulse rate and the pulse strength with an accuracy of within 2% of blood drawn levels. The design is simple and easy to use, and it gives the readings in about 10 seconds.
It’s suitable for most adults and children over 12 years old, and it features a bright LED screen that is easy to read. The batteries last for 40 hours, which is quite a lot considering that you only use the device for a few seconds at a time. The housing is hypoallergenic while the finger chamber has a unique spring system that makes it comfortable and easy to use.
It includes a silicone sleeve, a lanyard and comes with a warranty of 1 year (technical support by phone is also included). It comes with AAA batteries so you can use it right away.
The Wellue O2Ring Oxygen Tracker
While it’s more expensive, this device is much smaller and designed to be worn for extended periods of time (for example when doing sport activities, when hiking at high altitudes or when sleeping). It is small and light, and it alerts you when oxygen levels drop too low.
It works with the same technology as the devices used in hospitals, so the readings will be very accurate. It sends vibrations to your finger when the oxygen is low, so you know to take action depending on the activity you are doing at that moment. It is a chargeable device that offers 14-hours of use with a 2-hour charge.
It is an advanced and technologically sophisticated device that also comes with an app the shows a history of your readings and other important data. You can then send that information to your doctor (in case of medical use), or use the data to improve your performance (in case of sport activities). It has a premium price though.
The Accumed CMS-50DL Pulse Oximeter
This model comes with a durable housing and an included carrying case, so it’s great for traveling. It shows the SpO2 level as well as the pulse, and thanks to its unique design it can be used both by adults and children over 4. This makes it one of the broadest devices out there, so it’s perfect for the entire family.
It gives very fast readings (in 8 to 10 seconds) and has a special cover that reduces the influence of external light. It automatically turns off to improve battery life and can run for up to 24 hours of continuous use. It is designed for home use, exercising or traveling, and not for medical use.

This is one of the best devices on the market and it can be used by a wide variety of people (hikers, bikers, climbers, etc.) It is accurate and reliable, but also small and portable. This way you can measure your SpO2 and pulse rate anywhere and anytime.
But this is not all, because this oximeter also has 2 extra functions: Plethysmograph and Perfusion Index (PI). What are these strange medical terms you might ask? Well, the first one is the visual representation of your heartbeats and the PI is the numerical representation of the pulse strength.
These 2 features help you to get a more accurate measurement of the SpO2. For example, if the PI is smaller than 0.2%, it means that you have not placed your hands correctly in the oximeter, or that your hands are too cold. So in that case you need to warm your hands, position them better and then try again. The device also has an alarm function, a display that can be rotated in different directions.

Best Wearable Oximeter Buying Guide
There are plenty of models out there to choose from, so make sure to look at these aspects before buying one:
- Accuracy – it’s very important for the device to give an accurate reading. In case of home use oximeters, the accuracy should be within 2% of the levels shown in blood samples.
- Size – most devices are made based on the average fingertip size. So if you have much bigger or much smaller fingers, then the readings may not be accurate. Consult with your doctor and make sure to find the right oximeter for you.
- Warranty – some devices are quite expensive, so you need to make sure they will last you for years to come. Get one with an extended warranty and from a company that offers customer service and technical support. Sometimes you may have technical questions about the device, and you need to be able to discuss them with a specialist at any time.
- Ease of use – the device should be very easy to use and have a clear and easy to understand display. The last thing you want when you are low on oxygen and not feeling well is to try and decipher the readings on the oximeter.
- Battery Life – ideally, you want a tool that has a long battery life and automatically turns off after each use in order to save the battery. You really don’t want your oximeter to turn off right in a middle of a crisis and not be able to get readings that can be crucial.
