by Wellue • Model: Oxiband / O2Ring [cite: 165, 197]
The Wellue O2Ring is a lightweight, portable health oximeter worn on the finger to track functional oxygen saturation (SpO2) and pulse rate[cite: 198, 199, 1249]. Intended for adult patients in home and healthcare environments, it provides continuous data collection and features a vibration alert for low oxygen or abnormal heart rates[cite: 188, 207, 1289].

Evidence-based evaluation by medical professionals
"The most reliable consumer-grade ring for continuous overnight oxygen saturation tracking, backed by FDA clearance and clinical accuracy."
The Wellue O2Ring (Model: Oxiband/Checkme O2) is an FDA-cleared medical accessory designed for the continuous measurement and storage of blood oxygen saturation (SpO2) and pulse rate in adults. Unlike many lifestyle wearables that use reflective sensors, the O2Ring utilizes transmissive oximetry technology, which provides medical-grade accuracy across various finger sizes. Clinical validation under FDA submission K191088 confirmed its SpO2 accuracy within ±2% in the 80-100% range, making it a robust screening tool for nocturnal hypoxemia associated with sleep breathing disorders. A key differentiator is its built-in silent vibration alert, which triggers when SpO2 or pulse rate crosses user-defined thresholds, potentially prompting a position change during sleep. The device stores up to 4 sessions of 10-hour data internally and syncs automatically with the ViHealth app or PC software for detailed PDF/CSV reporting. While it lacks the advanced sleep staging features of consumer smartwatches, its singular focus on high-resolution respiratory data makes it an essential tool for those monitoring obstructive sleep apnea at home.
