ICU/cEEG technologists practice in accordance with the facility policy and procedure manual which details every aspect and type of recording.
ASET – The Neurodiagnostic Society presents this document to provide national criteria for evaluating competencies for performing studies associated with continuous EEG monitoring in neonatal Intensive Care Units (NICU/cEEG) with a postmenstrual age (PMA) of less than 48 weeks. The document was revised for consistency in terminology and approved by the ASET Board of Trustees in May of 2021.
In addition to advanced EEG knowledge and technical performance, quality patient care and patient/staff interaction were considered. The technical components include those defined in ASET’s published competency criteria documents: National Competency Skill Standards for Performing an Electroencephalogram and National Competency Skill Standards for Long-Term Monitoring in Epilepsy.
