See the list below:

  • Postconceptional age and topography

    • Determination of postconceptional age

    • Topography

      • Confirm head position.

      • Confirm the location of scars or intravenous lines.

      • Confirm any edema.

  • Artifacts

    • Locate artifacts.

    • Describe artifacts.

  • Identification of sleep and wake states

    • Determine cycling through awake, quiet, and active sleep states.

    • Analyze the distinctness of the changes in sleep state.

    • Determine and evaluate the duration of each sleep state.

    • Determine the presence of a quiet sleep pattern, TD, TA, or high-voltage slow wave.

      • Evaluate noncerebral physiological patterns and determine whether they are consistent with quiet sleep.

      • Determine whether the EEG pattern is appropriate for postconceptional age.

    • Determine whether REM sleep is continuous.

      • Determine whether noncerebral physiological patterns are concordant with quiet sleep.

      • Determine whether the pattern is appropriate for postconceptional age.

  • Feature extraction

    • Determine whether abnormalities in quiet sleep, active sleep, or wakefulness are present.

    • Determine amplitude.

    • Determine continuity.

    • Determine frequency.

    • Determine synchrony.

    • Determine maturation.

    • Note any paroxysmal abnormalities.

      • Interictal

      • Ictal

  • Classification of the record

    • Determine whether normal or abnormal.

    • Determine the clinical correlation.

    • Determine the need for follow-up.
