Conventional polysomnographic parameters fail to predict unrefreshing sleep in patients suspected of obstructive sleep apnea

Key Points

• Unrefreshing sleep is not effectively predicted by conventional polysomnography parameters, indicating a significant gap in sleep assessment.
• Clinical evaluation of obstructive sleep apnea patients reveals poor correlation between sleep parameters and reported sleep quality.
• Assessment relies on polysomnography, yet fails to address the subjective experience of unrefreshing sleep despite accurate apnea detection.
• The findings highlight the need for improved predictive models to better understand unrefreshing sleep in obstructive sleep apnea patients.
