Evaluation of WP200 With the Unified Probe (WP200U)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01929447
Recruitment Status : Completed

Brief Summary:

The prevalence of OSAS is estimated at 2% and 4% for adult women and men respectively, most of whom are undiagnosed and untreated. The severity of the disorder is expressed by the Apnea Hypopnea Index (AHI) which is the number of Apnea/Hypopnea episodes per hours of actual sleep and the Respiratory Disturbances Index (RDI) which is an extended index incorporating in addition to the previous episodes also respiratory effort related arousal episodes. The high cost of in-lab full night PSG, together with long waiting lists for sleep studies, have led to the development of a variety of ambulatory sleep study systems.

The primary objective of the study is to evaluate the newly developed WP200 with the unified probe (WP200U) compared to the currently used configuration of WP200 that uses an incorporated Nonin oximetry module in the sleep lab or in the home sleep environment.
