Actual date on which the first participant was enrolled.

This clinical study aims to validate a new system called the Smart Mask V1 System (SSAM) designed to monitor sleep stages and disturbances. The study focuses on patients with sleep-disordered breathing conditions, such as central or obstructive sleep apnea, who require assistance from devices like CPAP or BiPAP. The Smart Mask system is being tested to ensure it provides accurate results that are comparable to traditional manual methods (known as polysomnography) and an existing automated system called EnsoSleep. The research hopes to demonstrate that SSAM can reliably detect different sleep stages and disturbances, potentially offering a more efficient way to monitor sleep quality and improve the management of sleep disorders. Participants in this study will undergo overnight sleep evaluations at one of three specialized sleep centers, where they will wear the Smart Mask along with their prescribed sleep therapy device. During the sleep study, various physiological signals such as brain activity, eye movements, and heart rate will be recorded using a combination of sensors. The Smart Mask will process these signals to determine sleep stages and disturbances, which will then be compared to results from standard manual evaluations. Additionally, the study will collect data to train and validate the Smart Mask's ability to classify sleep patterns, ensuring it meets necessary performance standards. This research will help determine if the Smart Mask can be a reliable tool for diagnosing and managing sleep-related conditions.

Criteria

Inclusion Criteria: * Subjects must be at least 18 years of age at screening. * Subjects are individuals diagnosed with sleep-disordered breathing who have been prescribed PAP therapy or referred for a PSG. * Subjects must be willing and able to comply with the study requirements, which include using test, reference and predicate devices (if needed), completing training, interacting with study personnel and filling out questionnaires. * Subjects must be fluent in English. * Subject must be willing to undergo the screening and informed consent process prior to enrollment in the study. * Subjects must be deemed suitable candidates for this study based on the PI's evaluation of their condition and the features of the investigational device being tested. Exclusion Criteria: * Subjects unable or unwilling to wear a PAP mask as required for the study. * Subjects currently employed by, previously employed by or in any way affiliated (consulting, etc.) with any manufacturer or provider of PAP equipment and/or services. * Subjects who are pregnant. * Subjects with or requiring an implantable device, such as an electronic defibrillator, pacemaker, or other device. * Subjects considered by the PI to be medically unsuitable for study participation.

2 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Experimental
Participants in this arm will undergo a one-night, in-lab sleep study while wearing the Smart Mask and WatchPAT while receiving positive airway pressure ('PAP') therapy. Standard polysomnography ('PSG') data will be collected and stored. Three independent registered PSG technologists ('RPSGTs') will manually score the data to estimate sleep stages and arousals, following the guidelines in 'The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications', which is the definitive reference for the scoring of PSG and HSATs. PSG data will also be uploaded to EnsoSleep's cloud-based software system. Data from this phase will be used solely to train and refine the Smart Mask's neural network algorithms for detecting sleep stages and arousals. No algorithm validation will occur in this phase.

Group II

Experimental
Participants in this arm will undergo a single overnight, in-lab sleep study while wearing the Smart Mask and WatchPAT device, while receiving PAP therapy. Standard PSG data will be collected and stored. Data from the Smart Mask will be processed using trained neural networks to detect sleep stages (N1/N2, N3, REM, Wake), arousals, and calculate the Arousal Index. These outputs will be compared to: 1) manual scoring of PSG data by three independent, blinded RPSGTs; and 2) results from the predicate device, EnsoSleep. Data from this phase will be used validate the Smart Mask's neural network algorithms for detecting sleep stages and arousals.
