Alice PDx User/Validation Extended Trial
In Brief
A clinical study evaluating Alice PDx with only written instructions and Alice PDx with written and verbal instructions for Sleep Apnea and Sleep-Disordered Breathing. Completed, enrolled 32 participants across 2 sites.
Detailed Summary
The objective of this study is to test the usability of the Alice PDx device by both the end user (patient/participant) and the sleep technician. Data will be collected via questionnaires regarding the participant's ability to understand the participant user manual under home conditions and the technician's ability to set up the Alice PDx according to the health care provider manual. This study will also compare the physiological data recorded by the Alice PDx to the physiological data recorded by its predicate device the Alice 5 System and validate its equivalence. This will be evaluated by comparing the manual study scores for detected apnea and hypopnea events and on an event by event basis during a standard polysomnography (PSG)/ sleep study. The study will test the ability of the Alice PDx to record good quality data as determined by the Good Study Indicator (GSI) function of the Alice PDx firmware. The primary hypothesis is that the participant will be able to successfully apply the Alice PDx basic leads following the participant user manual instructions and the sleep technician will be able to successfully apply the advanced leads in preparation for the sleep study. In addition, it will be demonstrated that the Alice PDx is equivalent to the Alice 5 System in its intent to record, display and print physiological data to the clinician/physician in order to aid in the screening/follow-up diagnosis of respiratory sleep disorders.

Timeline
Interventions
Participants will be asked to follow the Alice PDx user instructions to apply basic leads and sensors and undergo a sleep study in their home. Participants will receive little or no instruction concerning the set up of the Alice PDx device. After the Alice PDx home study has proven successful, participants will return to the sleep center to undergo a second sleep study, the Lab Night, in which simultaneous monitoring with the Alice PDx and Alice 5 will be performed.
Participants will be provided instruction by a trained sleep professional on the set up of the Alice PDx device. They will then be asked to follow the instructions for the Alice PDx device, if necessary, and undergo a sleep study in their home. After the Alice PDx home study has proven successful, participants will return to the sleep center to undergo a second sleep study, the Lab Night, in which simultaneous monitoring with the Alice PDx and Alice 5 will be performed.
