Sleep Apnea

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Background:

Manual polysomnogram (PSG) analysis is crucial for diagnosing sleep disorders.
Automating PSG analysis is a key trend for efficiency and consistency.
Reliable artifact detection is essential for accurate automated sleep analysis.

Purpose of the Study:

To investigate an automated approach for compensating specific PSG artifacts.
To develop a reliable pre-processing tool for automated human sleep analysis systems.

Main Methods:

Application of the generalized singular value decomposition (GSVD) algorithm.
Automated discrimination between outlier/artifact instances and relevant data in PSG signals.

Main Results:

The generalized singular value decomposition algorithm was successfully applied to compensate for specific PSG artifacts.
Demonstrated the potential for automated artifact compensation in sleep data.

Conclusions:

Automated artifact compensation using GSVD is a viable strategy for enhancing PSG analysis.
This method contributes to the development of more efficient and reliable automated sleep analysis systems.
