Arm Label
AL + polysomnography
Arm Description
Participant wears an Apnea Link sleep apnoea screening device during the polysomnography to detect apnoeas (obstructive, central).
Outcomes
Primary Outcome Measures
Assessment of the Apnoea-Hypopnea-Index (Number of Apneas (All Apneas, Obstructive, Mixed, Central) and Number of Hypopneas) Between ApneaLink Plus and a PSG System Within the Same Evaluation Period
Apnoea is defined as a decrease in flow of ≥90% from baseline for at least 10 seconds; hypopnea is a decrease in flow ≥30% from baseline for at least 10 seconds and an oxygen desaturation of ≥4%; obstructive: breathing efforts are ongoing; central: no breathing efforts
Correlation Coefficient of Apnoea-Hypopnea-Index (AHI) (PSG) - AHI (AL)
The AHI (PSG) values and AHI ApneaLink Plus (AL) value will be collected in one graph (Bland-Altmann Plot) and the correlation coefficient will be calculated. A correlation of >75% will be seen as threshold for validity.
Correlation Coefficient of Apnoea-Index (AI) (PSG) - AI (AL)
The AI (PSG) values and AI ApneaLink Plus (AL) value will be collected in one graph (Bland-Altmann Plot) and the correlation coefficient will be calculated. A correlation of >75% will be seen as threshold for validity.
Correlation Coefficient of Obstructive-Apnoea-Index (OAI) (PSG) - OAI (AL)
The OAI (PSG) values and OAI ApneaLink Plus (AL) value will be collected in one graph (Bland-Altmann Plot) and the correlation coefficient will be calculated. A correlation of >75% will be seen as threshold for validity.
Correlation Coefficient of Central-Apnoea-Index (CAI) (PSG) - CAI (AL)
The CAI (PSG) values and CAI ApneaLink Plus (AL) value will be collected in one graph (Bland-Altmann Plot) and the correlation coefficient will be calculated. A correlation of >75% will be seen as threshold for validity.
Correlation Coefficient of Apnoea-Index (HI) (PSG) - HI (AL)
The HI (PSG) values and HI ApneaLink Plus (AL) value will be collected in one graph (Bland-Altmann Plot) and the correlation coefficient will be calculated. A correlation of >75% will be seen as threshold for validity.
Correlation Coefficient of Obstructive-Apnoea-Index (ODI) (PSG) - ODI (AL)
The ODI (PSG) values and ODI ApneaLink Plus (AL) value will be collected in one graph (Bland-Altmann Plot) and the correlation coefficient will be calculated. A correlation of >75% will be seen as threshold for validity.

5. Study Description
Brief Summary
The purpose of this study is to investigate the following topics:
Determine the accuracy of ApneaLink Plus in separating Apneas into Obstructive Apneas, Mixed Apneas and Central Apneas.
Determine the accuracy of ApneaLink Plus in scoring Hypopneas according to the 2008 guidelines of the AASM = American Academy of Sleep Medcine.
Determine whether patients can start and stop the recorder and are able to attach the additional effort sensor by themselves using the patient instruction sheet
