Respiratory failure & ventilation
Effect of Atypical Sleep EEG Patterns on Weaning From Prolonged Mechanical Ventilation
Authors' conclusion
This study provides the first evidence that patients in a long-term acute care facility being weaned from prolonged ventilation exhibit atypical sleep EEG patterns that are associated with weaning failure.
Study context
- Population
- Alert, nondelirious patients being weaned from prolonged mechanical ventilation at a long-term acute care facilitymedian ventilation 38 days
- Participants
- 44 participants
- Exposure
- Atypical sleep EEG vs usual sleep
- Atypical sleepn = 11
- Outcome
- Atypical sleep EEG patterns and their link with weaning outcomes

Main finding
As reported in the abstract
Atypical sleep EEG (prevalence) and weaning failure
Atypical sleep EEG (prevalence) and weaning failure Atypical sleep 25%
Weaning failure
- Atypical sleep vs Usual sleep: P = 0.013 — 91% vs 45%
Observational data: associations, not effects.

P = 0.027
Rapid eye movement sleep (% total sleep time)
P < 0.02
| Outcome | Atypical sleep | Usual sleep | P value |
|---|---|---|---|
| Relative delta power during wakefulness | 53% | 41% | P < 0.001 |
| Slow-to-fast power ratio during wakefulness | 4.39 | 2.17 | P < 0.001 |
