New Obstructive Sleep Apnoea Multi‐Night Diagnostic Devices. Is a Single Night of Measurement Now Considered Enough?

Key Points

• To determine if a single night of testing for obstructive sleep apnoea is sufficient for accurate diagnosis compared to multi-night testing.
• Evaluated the variation of the apnoea-hypopnoea index across multiple nights.
• Assessed emerging multi-night diagnostic devices for practical advantages and validation needs.
• Multi-night testing improves diagnostic accuracy compared to a single night.
• The apnoea-hypopnoea index varies significantly from night to night, suggesting single night estimates may be unreliable.
