Abstract
Garmin is a shopper wearable machine with exercise, ECG, coronary heart charge, and pulse oximetry as the important thing parameters captured, which permit the monitoring of well being metrics equivalent to health, sleep, coronary heart rhythm, and vitality/calorie expenditure. The evaluation makes use of accelerometry together with PPG modifications in coronary heart charge and rhythm for sleep rating, monitoring, and levels (gentle, deep, REM, wake). Along with sleep monitoring, it presents a sleep coach, nap detection, and jet lag advisor. Some Garmin gadgets additionally observe ECG, respiratory charge, SpO2, stress ranges, HRV, energy, a number of health metrics, GPS, and/or pores and skin temperature. Garmin has a number of wrist-based wearable merchandise with various options, together with the Venu®, Fēnix®, Forerunner (has GPS), the Intuition®, and others. The Venu® has an FDA-cleared utility that enables customers to file their 1 channel ECG and to verify for indicators of atrial fibrillation together with exercise monitoring to estimate sleep. Coronary heart rhythm outcomes could also be considered with the watch’s ECG app or the Garmin Join™ smartphone app. Its accelerometry efficiency is reportedly corresponding to different wearable gadgets, and it has utility for sleep/wake assessments.
Claimed Capabilities/Measurements
Garmin presents a number of watches and wristbands meant to watch and promote well being and wellness utilizing accelerometry and PPG that present customers with exercise and sleep-related data. A few of the smartwatches have an FDA-cleared ECG app that enables customers to file ECG and to verify for indicators of atrial fibrillation (AFib) or regular sinus rhythm.
Mechanism
Movement, ECG, HR, HRV, SpO2
Sensors
Accelerometer; optical PPG sensor
Technical Concerns
Every battery life will depend on the watch/ wristband, usually 1 week to 1 month.

Research Abstract: The authors did a scientific overview trying on the validity and reliability in adults of Garmin watches for steps, distance, vitality expenditure, pace, elevation, coronary heart charge, and sleep. 32 research documented validity and 4 additionally documented reliability. There have been quite a few research limitations together with the usage of completely different watch fashions. For sleep, no research assessed reliability, and the one two research that assessed validity for Garmin exercise trackers used sleep diaries for comparability, not PSG. The authors discovered “greater validity of steps; few research on pace, elevation, and sleep; decrease validity for distance, vitality expenditure, and coronary heart charge;” and the necessity for extra intra- and inter-device characteristic reliability testing.

Comparability Check(s): Polar Ignite, Actigraph GT9X, and PSG
Research Abstract: Two industrial kind exercise trackers (Garmin Forerunner 945 and Polar Ignite) and an accelerometer (Actigraph GT9X) have been in contrast with PSG adopted by MSLT for 49 (30 males/19 females) suspected of sleep problems. The exercise trackers have been extremely correct for HR, HRV, SpO2, and RR however each overestimated TST and underestimated WASO and SL. Each deviated with sleep levels, overestimated gentle sleep, and underestimated deep sleep. The authors concluded that they have been ample for detecting sleep/wake patterns and very important indicators however not for medical functions or if correct sleep staging is required.

Research Abstract: The authors did a scientific overview to guage the efficiency of three current wearable gadgets (Fitbit Cost 4, Garmin Vivosmart 4, and WHOOP) for figuring out sleep parameters and sleep levels. Utilizing 8 papers, they discovered that “WHOOP confirmed the least disagreement relative to PSG and Sleep Profiler for complete sleep time (−1.4 min), gentle sleep (−9.6 min), and deep sleep (−9.3 min) however confirmed the biggest disagreement for speedy eye motion (REM) sleep (21.0 min). Fitbit Cost 4 and Garmin Vivosmart 4 each confirmed reasonable accuracy in assessing sleep levels and complete sleep time in comparison with PSG. Fitbit Cost 4 confirmed the least disagreement for REM sleep (4.0 min) relative to PSG. Fitbit Cost 4 confirmed greater sensitivities to deep sleep (75%) and REM sleep (86.5%) in comparison with Garmin Vivosmart 4 and WHOOP.” The authors concluded that, along with extra wanted analysis, the gadgets derive acceptable sleep estimates however all gadgets may gain advantage from bettering particular sleep levels.
