Objectives

Narrative objectives1

Polysomnography (PSG) is known as the gold standard to make a diagnosis and severity of sleep apnea syndrome. The national health assurance permits to use nasal positive airway therapy when apnea hypopnea index (AHI) is equal to or higher than 20 times/h using PSG or 40 times/h using simplified PSG in Japan. Analysis of PSG is usually performed by a polysomnographer authorized by Japanese Society of Sleep Research. However, scoring variability between polysomnography technologists in different sleep laboratories has been reported, and recently new equipment for PSG study are also developed. Although reproducibility of scorings by different polysomnographers has been confirmed in a few scoring companies, inter-variabilities among different companies or different equipment are yet to be done. Therefore, the major outcome is uniformity of AHIs obtained by different equipment and different scoring companies.

Basic objectives -Others

When AHIs obtained by different equipment and different scoring companies are significantly differ, some parameters obtained by PSG are set as description variables.

Results

The difference in AHI between Group A (Alice+Phillips) and Group N (Nox+Teijin) was significant. In multiple correlation analysis, the prediction equation was established for two indices in both groups, ODI and arousal response (AIx), with a greater contribution from AIx in group A and from ODI in group N. ODIs are objective changes, but AIx is largely dependent on the analyst's subjectivity, so it is assumed that the evaluation of AIx influenced the difference in AHI.
