Pulse Ox data should not be treated as any type of medical diagnosis or treatment of disease. This is not a medical device: see Garmin. What is Pulse Ox? Why should I be interested in Pulse Ox tracking? How can I use the feature?

Essentially this is the oxygen saturation within the blood; the percentage of haemoglobin carrying oxygen. The device shines a light into the fingertip and by measuring the amount of refracted and absorbed light it can calculate the percentage of haemoglobin carrying oxygen. Cycling coach James Spragg unpacks the topic Working both in research and applied settings, he currently runs Intercept Performance Consultancy. The good news is that the Garmin and Apple measurements have been assessed — so we know what we are dealing with. The results show that there are some differences between the measurements taken from smartwatches and the gold standard measurements. We can expect between So it would be fair to say that the measures are not bad, but not amazing either. The next thing we should consider with any measure is useability or actionability… What can we do with the information? Can it inform our training? The level at which it stabilises, and how quickly it stabilises, is dependent on the altitude and the athlete.

Garmin devices are some of the best for tracking your performances, following up on your training, hiking without getting lost, and measuring key health metrics. The Heart rate and Heart Rate Variability are critical vitals but also is the blood oxygen saturation also referred to as pulse Ox, or SpO2. Many smartwatch manufacturers, such as Apple, Fitbit, Xiaomi, Huawei, and many others, have integrated a built-in oximeter. So even if Garmin gained its reputation based on the accuracy of its navigation systems, the company is now expanding its range of wearables to include a pulse oximeter feature. We tested the pulse ox accuracy of two of the most recent Garmin models: the Vivosmart 5 fitness tracker and the Forerunner smartwatch. Unfortunately, the results were not what we expected!

Squeezing high-end features into a more affordable frame makes for an excellent mid-range smart sports tracker. The watch comes in a choice of colours but only one size, with a 1. It has the same great combination of touchscreen and five buttons as recent Garmin watches. It syncs data to an Android or iPhone through the Connect app , via USB cable to your computer or direct to the internet through wifi if you buy the more expensive version with offline music playback. The battery lasts about five days between charges with the screen on all the time, tracking sleep overnight and a single minute run.

Criteria for study inclusion were patients 18—85 years old, with and without respiratory disease, who were receiving care at Duke Hospital and Clinics, a tertiary referral center. In: FDA [Internet]. The results show that there are some differences between the measurements taken from smartwatches and the gold standard measurements. The study would have been much more powerful if ABG had been used as the gold standard, however with some modifications I think the paper could be published with more limitations acknoweldged. Journal of Medical Internet Research. To our knowledge, this is the first study to explore the accuracy of blood oxygen saturation measurements from consumer smartwatches as well as patterns of missingness, error, and bias in patients likely to experience intermittent oxygen desaturations. James Spragg. For the study procedure, the smartwatches were placed tightly on the wrist, approximately one centimeter above the ulnar styloid process. The mean absolute error MAE , mean directional error MDE and root mean squared error RMSE were used to evaluate the accuracy of the smartwatches as compared to a clinical grade pulse oximeter. To use PACE, you must first register as a user.

These limitations should be acknowledged and discussed in the manuscript. So would I pay much attention to the Pulse Ox on my smartwatch? Mol Biol Rep. GB Edition. The MDE ranged from Please upload your review as an attachment if it exceeds 20, characters Reviewer 1: This study compares the accuracy and reliability of SpO2 measurements from consumer smart watches to a commercially available pulse oximeter. A significant limitation of this study is that the consumer watch pulse oximeters are directly compared to another device that has known racial biases, therefore this bias is not accounted for in this study when measuring the reliability and accuracy of the smart watches. Racial effects on Masimo pulse oximetry: a laboratory study. In each round, three measurements of HR and SpO 2 were captured from each watch and the pulse oximeter while the participant was at rest, with approximately three minutes between measurements. If Pulse Ox tracking during sleep or all-day is turned on, the battery life on a full charge may be reduced significantly.
