Obstructive Sleep Apnea and Cognitive Impairment: Implications for Surgical Outcomes.

Journal of sleep research·2026

The Embletta X100 portable sleep device is a reliable alternative to standard polysomnography (PSG) for surgical patients, especially when using manual scoring by a trained technician.

Area of Science:

  • Medical Devices
  • Sleep Medicine
  • Respiratory Physiology

Background:

  • Standard polysomnography (PSG) is the gold standard for diagnosing sleep disorders.
  • Portable sleep devices offer potential advantages in accessibility and cost-effectiveness.
  • Surgical patients often have complex sleep needs requiring accurate monitoring.

Purpose of the Study:

  • To evaluate the Embletta X100, a level 2 portable sleep device, as a reliable alternative to standard PSG.
  • To assess the accuracy and correlation of Embletta X100 data with standard PSG in surgical patients.

Main Methods:

  • Simultaneous standard PSG and Embletta X100 recordings in a sleep laboratory for validation.
  • Perioperative sleep studies using Embletta X100 in a larger patient cohort.

  • Correlation analysis and paired Student t tests to compare device accuracy.
  • Assessment of recording quality and inter-rater agreement for manual scoring.

    • Main Results:

    • Significant correlation between Embletta X100 and standard PSG parameters with manual scoring.
    • Substantial to perfect inter-rater agreement (Kappa 0.69-1) for AHI cutoffs.
    • Good technical success rate (97.7%) for Embletta X100 in 1,002 perioperative recordings.
    • Automatic scoring showed significant correlation only in AHI and limited parameters.

    Conclusions:

    • Embletta X100 is a viable alternative to standard PSG for surgical patients when PSG is unavailable or impractical.
    • Manual scoring by a certified technologist is crucial for ensuring the reliability of Embletta X100 results.
    • The device demonstrates high technical success rates in perioperative settings.
