Detailed Description
Study name: Validation of a Ring-type Wearable Device for Blood Oxygen Monitoring and Obstructive Sleep Apnea Syndrome Screening in Adult Chinese.
Rationale: Obstructive sleep apnoea syndrome (OSAS) is a common chronic sleep-related breathing disorder characterized by repetitive upper airway collapse during sleep, which causes sleep fragmentation, oxygen desaturation, and excessive daytime sleepiness. Previous studies have identified that OSAS is significantly correlated with the risk of cardiovascular and cerebrovascular diseases. Overnight polysomnography (PSG) is the gold standard for diagnosing OSAS at present. However, PSG monitoring requires professional technicists and a lot of channels, which brings inconvenience to both patients and doctors. Wearable devices are growing in popularity and become comfortable, lightweight and technologically advanced for tracking sleep and daily activity.
Objective: 1) To examine the accuracy of blood oxygen monitoring assessed via a ring-type wearable device in comparison to traditional finger clip pulse oximeter; 2) To assess the agreement between the ring-type wearable device and PSG monitor on OSAS screening.
Study design: Clinical diagnostic trial.
Study population: Individuals who are willing to participate in the study and sign the informed consent are considered to be eligible. Specific inclusion criterias include: 1) Agree to receive overnight polysomnography and wear the ring-type device at the same time; 2) At least 18 years old.
Data collections: 1) Data on demographic and clinical characteristics were collected using a questionnaire; 2) Data on blood oxygen saturation and sleep apnea-related parameters were measured by both PSG monitoring and the ring-type wearable device.
Sample size estimation: About 200 participants.
Timeline: Start of subjects' enrollment: Dec 2022; End of subjects' enrollment: Oct 2023; End of study: Oct 2023.
Organization: The Centre for Epidemiological Studies and Clinical Trials, Ruijin Hospital, Shanghai, China.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Ring-type wearable device The ring-type wearable device achieved continuous monitoring of blood oxygen saturation during sleep and established a OSAS screening algorithm based on oxygen saturation, which might become a complement to polysomnography. |
Device: Ring-type wearable device
The ring-type wearable device is a slim, lightweight smart ring that continuously tracks blood oxygen saturation and heart rate throughout the day.

| Active Comparator: Polysomnography Overnight polysomnography (PSG) monitor was used as the gold standard to: 1) examine the accuracy of blood oxygen monitoring assessed via a ring-type wearable device in comparison to traditional finger clip pulse oximeter; 2) assess the agreement between the ring-type wearable device and PSG monitor on OSAS screening. |
Device: Overnight polysomnography
Overnight polysomnography is the gold standard for diagnosing OSAS.

Outcome Measures
Primary Outcome Measures
- Difference in the mean oxygen saturation [1 night]
Secondary Outcome Measures
- Difference in the lowest oxygen saturation [1 night]
- Difference in the apnea-hypopnea index [1 night]
- Difference in the oxygen desaturation index [1 night]
- Difference in the hypoxic burden [1 night]
- Agreement between the ring-type wearable device and PSG monitor on OSAS screening [1 night]
Sensitivity, specificity, positive predictive value, negative predictive value and area under the ROC curve were used to describe the agreement between the ring-type wearable device and PSG monitor on OSAS screening
