Ring-type Pulse Oximeter for Evaluation for Sleep Assessment Study

NCT ID: NCT06221124

Last Updated: 2024-01-24

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 40 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2020-07-15
• Study Completion Date: 2023-06-12

Brief Summary

Recently, various electronic lifestyle activity monitoring devices (ELAM) are increasingly commercially available. However, the quality and reliability of the data from ELAM are unclear, compared with polysomnography (PSG), which is the gold-standard sleep assessment method. Thus, combining ELAM with PSG will validate ELAM and improve its clinical and research utilization.

The investigators propose to conduct this study to validate ELAM device for sleep assessment. The investigators will compare Belun Ring data collection and overnight in-lab PSG measures of Sleep-Disordered Breathing (SDB) and sleep architecture in adults with obstructive sleep apnea (OSA) symptoms.

The investigators propose to recruit a total of 40 participants with symptoms of OSA. The overall accuracy, sensitivity and specificity of Belun Ring to assess SDB and sleep architecture will be validated by using PSG analysis as a gold standard.

Conditions

Sleep-Disordered Breathing; Sleep Architecture

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: DIAGNOSTIC
• Blinding Strategy: NONE

Study Groups

BEL-Participant

First, we will measure the size of the finger of the participant and select appropriate size of Belun Ring device and the participant will be instructed to wear it on a finger in addition to regular PSG set up on the night of sleep study. Simultaneous recording of Belun Ring data {pulse oximeter, pulse rate and actigraphy} and standard PSG will be performed for one night.

Group Type: EXPERIMENTAL

Belun Ring Pulse Oximeter

Intervention Type: DEVICE

Belun Ring Pulse Oximeter allows measurement and analysis of oximetry, pulse rate, photo-plethysmography (PPG), and accelerometer signals from the proximal phalanx of index finger. Sleep stage (bSTAGES) and respiratory event index (bAHI) are estimated.
