Area of Science:

  • Clinical Neurophysiology
  • Neurodiagnostics
  • Intensive Care Medicine

Background:

  • Electroencephalography (EEG) is crucial for neurodiagnostics in critically ill patients.
  • The intensive care unit (ICU) presents challenges for acquiring quality EEG due to frequent artifacts.
  • Effective artifact management is a key skill for EEG technologists in the ICU.

Purpose of the Study:

  • To review common physiological and nonphysiological artifacts encountered in ICU EEG recordings.
  • To provide guidance for novice EEG technologists on artifact recognition and troubleshooting.
  • To enhance the quality of EEG tracings obtained in the ICU setting.

Main Methods:

  • Literature review of common ICU EEG artifacts.
  • Discussion of artifact recognition and troubleshooting strategies.
  • Guidance on differentiating artifactual patterns from true EEG activity.

Main Results:

  • Identification of prevalent physiological artifacts (e.g., muscle movements, patient-ventilator interactions).
  • Identification of prevalent nonphysiological artifacts (e.g., electrical interference, lead dislodgement).
  • Strategies for effective artifact mitigation and validation presented.

Conclusions:

  • Mastering artifact identification and management is essential for quality ICU EEG.
  • This review equips novice technologists with practical skills for challenging ICU environments.
  • Improved EEG quality in the ICU leads to more reliable neurodiagnostic assessments.
