简要总结
The goal of this clinical trial is to evaluate the effectiveness of the Wesper Lab home sleep apnea test as a tool to aid in the diagnosis of sleep apnea in adult patients (age ≥21 years) who are recommended for an overnight polysomnography (PSG) evaluation. The main questions it aims to answer are:
- Is Wesper Lab home sleep apnea test as accurate as an in-laboratory sleep study (polysomnography) for the diagnosis of obstructive and central sleep apnea?
- Is Wesper Lab accurate in a wide range of body types and skin types?
Participants will:
- Provide informed consent and complete a brief medical history.
- Undergo an overnight polysomnography sleep study while wearing two Wesper Lab patches and a compatible pulse oximeter.
- Have a follow-up communication within 5 days post-study to assess any adverse events.
详细描述
This study aims to validate the Wesper Lab wireless sensors as a reliable alternative to traditional PSG for diagnosing sleep apnea, potentially providing a more convenient method for patients while maintaining diagnostic accuracy. The structured approach to data collection, monitoring, and follow-up underscores a thorough methodology to assess both effectiveness and safety. The study is a single-center, single-arm clinical trial designed to evaluate the effectiveness of the Wesper Lab wireless sensors for aiding in the diagnosis of sleep apnea, specifically comparing its performance to overnight polysomnography (PSG).
The primary aim is to determine how well the Wesper Lab wireless sensors correlate with traditional PSG results in measuring obstructive sleep apnea (OSA) and central sleep apnea (CSA) through key metrics, specifically the apnea-hypopnea index (AHI) and central apnea/hypopnea index (CAHI).
Approximately 100 eligible adult patients (≥21 years) who have been referred by a physician for an overnight PSG test to evaluate sleep apnea.
Patients will undergo PSG testing while simultaneously wearing two Wesper Lab sensors and a compatible pulse oximeter for one night at the clinic. Sleep technicians will monitor and set up the devices, and data will be collected via a smartphone app linked to the Wesper Lab system. The PSG will record brain activity, blood oxygen levels, heart rate, breathing patterns, and movements. Data will be collected during the sleep period, and post-study, the signals will be analyzed by qualified readers who are blinded to the device used for data collection.
To demonstrate that the correlation between the AHI/CAHI from the Wesper Lab and PSG exceeds a predefined performance goal (PG) using Pearson correlation. To establish that the 95% limits of agreement between AHI/CAI from the two devices fall within acceptable upper and lower limits. Evaluate inter-rater reliability of AHI/CAHI readings. Assess agreement in apnea classification (mild, moderate, severe) between the two methods.

盲法说明
A blinding model will be implemented for the scoring of the Wesper Lab data and Polysomnography (PSG) to minimize bias during the scoring and analysis of sleep study data.
All sleep study recordings are disidentified before being presented to the readers. The primary reader and any additional secondary readers will be blinded to which device was used to collect the data (Wesper Lab vs. PSG). Studies will be reviewed in a predetermined randomized order to further prevent any bias. All data will be presented using the same viewing and scoring platform, ensuring consistency in how the data is labeled and displayed.
