Background: Poor sleep is a major concern in intensive care units (ICUs), particularly in mechanically ventilated patients, because it is associated with longer duration of the weaning phase and higher mortality. High noise levels in ICUs are frequently reported by patients as one of the most disturbing sleep-disrupting factors but would be responsible for less than 20% of arousals. This suggests major inter-individual variability in noise sensitivity.

Methods: Origin of the early exhaustion after SD might be insufficient cortical motor drive to muscle or motor inhibition because of excessive perception of effort.
Article Synopsis
- Sleep deprivation is prevalent in ICUs and can negatively impact respiratory performance, yet its effects on critically ill patients' outcomes are not well-studied.
- The study analyzed sleep patterns in 131 patients using polysomnography to see how sleep disturbances relate to clinical outcomes, particularly focusing on those with acute respiratory failure.
- Findings showed that while deep sleep is maintained in certain cases, REM sleep is often disrupted, and a complete lack of REM sleep correlates with worse clinical outcomes in patients.
Article Synopsis
- * In a study involving 72 extubated patients from an ICU, researchers examined the relationship between sleep continuity measured by EEG and patient-reported sleep quality using the Richards-Campbell sleep questionnaire (RCSQ) and a simpler sleep numeric rating scale (sleep-NRS).
- * Results indicated a significant correlation between sleep continuity and sleep-NRS scores, whereas no correlation was found with RCSQ, suggesting that the numeric rating scale may be a more straightforward tool for assessing sleep quality in ICU patients.
Objectives: Due to the noisy environment, a very large number of patients admitted to intensive care units (ICUs) suffer from sleep severe disruption. These sleep alterations have been associated with a prolonged need for assisted ventilation or even with death. Sleep scoring in the critically ill is very challenging and requires sleep experts, limiting relevant studies to a few experienced teams.
