Study 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.
Primary Outcome
The Apnea-Hypopnea Index (AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep. The AHI detected events of Alice 5 system was compared to the AHI events of the Alice PDx.
Interventions
