Small variations in your estimated oxygen saturation levels are typical (source). Frequent big variations on your estimated oxygen variation graph may indicate that you experience breathing disturbances during sleep. Breathing disturbances can lead to higher than expected variations in blood oxygen levels, which can indicate that your body is not getting enough oxygen while you sleep. If you frequently see big variations on your graph, consider talking to your doctor, particularly if you experience symptoms such as excessive tiredness, loud snoring, or gasping during sleep.
Other factors, including your arm position and certain physical characteristics, can affect your estimated oxygen variation readings, making them appear to be more variable. Make sure your Fitbit device is snug and secure on your wrist. For more information, see How do I wear my Fitbit device?
Fitbit’s small print says its blood-oxygen app is “not intended to diagnose or treat any medical condition” and is useful to “help you manage your well-being and keep track of your information.”. Of course, Fitbit isn't the first company to offer SpO2 monitoring in its wrist-worn fitness gadgets. Garmin's watches have featured a Pulse Oximeter (Pulse Ox) tracker for a little while now, but. Your SpO2 is a measure of your blood oxygen levels, or as Fitbit refers to it, your estimated oxygen variation (EOV). According to Fitbit's help center: Typically, your blood oxygen saturation level is between 95-100%, which means your blood is carrying as much oxygen as it can.
Fitbit SpO2 data is not intended for medical purposes, nor is it intended to diagnose, treat, cure, or prevent any disease or condition. The data provided by Fitbit SpO2 is intended to be a close estimation of your blood oxygen saturation levels, but may not be precisely accurate. You should not use or rely on Fitbit SpO2 for any medical purposes.

1. Huawei Honor Band 5
Editor’s Rating: 4.8/5
The Huawei Honor Band 5 is an affordable fitness tracker offering a stylish design and plenty of useful features. Download soapui for mac. Despite being well-known for its smartphones, Honor has also been making significant strides with its fitness trackers, and the Band 5 represents the company’s best option so far.
Design
The Honor Band 5 looks very much like its predecessor, the Band 4. This isn’t a bad thing, as the Band 4 is by no means an ugly device, but a bit more of a facelift would have nice to see.
The device has a rather simple design, with a sleek form factor that offers very few gimmicks. This is good to see from the Band 5, as many fitness trackers try too hard to stand out these days, which often leaves them looking cheap or unappealing.
The display on the device uses a 0.95-inch AMOLED panel, which is both clear and vibrant. This means you should have no issues viewing any of the information on the display. However, it is notably smaller than some of the other options in this guide.
The Band 5 measures 17.2mm in width, which is in keeping with the average footprint of most fitness trackers. This means you should have no issues with the size of this device, and it shouldn’t overhang your wrist. The device is also only 11.5mm thick, meaning bulkiness shouldn’t be a problem either.
The casing is made from plastic, which could leave it prone to damage, especially if it encounters a heavy drop or impact. For this reason, a metal casing would have been preferred. However, due to the device’s price point, we are not surprised that Honor decided to use plastic instead.
The strap is made from silicone, giving it a soft surface that will provide plenty of comfort, even if you choose to wear the device tightly. Silicone is also non-porous, meaning it won’t soak up sweat and discolor over time.
The device is also water-resistant up to 50 meters, making it perfectly suitable to swim with, or to use while taking part in other water-based activities. One activity we recommend avoiding, however, is diving, as there is a chance you could still damage the device, even at shallower depths.
Features
Fitbit Pulse Ox Accuracy
The Band 5 comes with a rather extensive feature-set that includes a pulse oximeter, activity tracking, heart rate monitoring, sleep tracking, sedentary reminders, connected GPS, and one-way notifications. The device can also be used as a remote shutter when taking photos with your smartphone.
The pulse oximeter on the device works primarily during the night to measure your blood oxygen levels while you sleep. However, you can also manually take readings during the day as well.

Measuring blood oxygen levels isn’t the only tool in this devices sleep tracking arsenal, however, as it can also identify and provide advice on a number of common sleeping issues such as insomnia and restless sleep. This is a great feature to include on the device, as many people suffer from sleep issues they aren’t even aware of.
When it comes to heart rate monitoring, the Band 5 is hard to fault. At Honor’s launch event for the product, the company showcased the devices heart rate monitor by pitting it against an actual EKG. Incredibly, the Band 5 was within a few beats per minute on every reading. This makes it highly accurate compared to most fitness trackers, making it an attractive option if this feature is important to you.
The device also works well as a daily assistant, thanks to its inclusion of a one-way notification system. This feature can be used to inform you of a variety of different notifications, as well as weather reports, and incoming calls. The Band 5 also has a built-in feature to help you find your phone if you ever lose it.
Battery life
Fitbit Watch With Pulse Oximeter
The device can last up to 6 days on a single charge, which is pretty admirable for a fitness tracker with this many features. You can also turn off certain features on the device to preserve battery life if you wish, which could be useful if you go away for a while and forget your charger.
This device hardly puts a foot wrong. Its feature-set is among the best we’ve seen at this price point, and its design is both compact and stylish. There are some durability concerns, due to the use of plastic for the casing, but overall, this is a brilliant device that offers excellent value for money.
