What can be a consequence of improper EEG signal settings?

Improper EEG signal settings can significantly affect the accuracy of sleep stage detection. When the settings are not configured correctly, the EEG may not accurately reflect the brain's electrical activity during different sleep stages. This can lead to misinterpretation of the data, resulting in an incorrect diagnosis or understanding of the patient’s sleep architecture.

For example, if the sensitivity settings are too low, subtle changes in brain activity that differentiate between REM sleep and non-REM sleep may be missed. Alternatively, if the filter settings are not optimal, artifacts and noise can obscure important signals. This not only complicates the analysis but can also lead to inappropriate management strategies for conditions such as obstructive sleep apnea or insomnia. Therefore, maintaining accurate EEG settings is crucial for effective polysomnography and reliable clinical outcomes.
