Brief summary
The current study is a prospective blinded study to collect data regarding the performance of the WP device in detecting sleep disorders. For that purpose, the WP with finger probe and chest sensor will be worn by the subject simultaneous to PSG in a sleep study at the clinical sleep lab. A PSG system will be recording the PSG data.
Detailed description
Subjects suspected of having sleep disorders who are referred to a sleep study will be screened for potential participation in the study, according to the inclusion and exclusion criteria. Additionally, patients with comorbidities associated with central sleep apnea may be referred from cardiology related divisions, and screened for participation in the study. Recruited patients will be asked to sign an informed consent form. Subject demographic and medical information will be acquired from the subject himself and/or from the subject's medical chart and will be recorded on the appropriate case report forms. The subjects will be admitted to the clinical sleep laboratory for one night, during which they will undergo conventional full night PSG recording with the standard PSG channels. The WP with finger probe and chest sensor will be worn by the subject simultaneous to PSG. A PSG system will be recording the signals and manual scoring will be performed blinded - without access to WP data. The WP analysis will be done automatically.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Apnea- Hypopnea Index (AHI) | one night of sleep | Compares the results of the automatically scored AHI of the WP to the manually scored AHI of the PSG (Gold Standard). AHI is the average number of apnea and hypopnea events per hour of sleep |
| Sleep Stages | one night of sleep | Compares the results of the automatically scored sleep stages of the WP to the manually scored sleep stages of the PSG (Gold Standard). Stages are light sleep, deep sleep, REM or Wake. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Respiratory Disturbance Index (RDI) | one night of sleep | Compares the results of the automatically scored RDI of the WP to the manually scored RDI of the PSG (Gold Standard). RDI is the average number of respiratory events per hour of sleep |
