Question | Answer |
---|---|
ACNS - What is the ACNS? | The American Clinical Neurophysiology Society. A professional association dedicated to fostering excellence in clinical neurophysiology and understanding of CNS & PNS function in health and disease through education, research, discussion forum. |
ACNS - Guideline 1: | Minimum Technical Requirements for Performing Clinical Electroencephalography. |
ACNS - Guideline 2: | Minimum Technical Standards for Pediatric Electroencephalography. Appropriate reduction of sensitivity (to 10 µV/mm or even 15 µV/mm) should be used. Passive eye closure (by placing hand over the pt’s eyes), allow extra time for common mvt artifact. |
ACNS - Guideline 3: | Minimum Technical Standards for EEG Recording in Suspected Cerebral Death. (ECI) or (ECS). Since, prior to the recording, one does not know whether an ECI record will be obtained, use a full set electrodes in init'l examination. |
ACNS - Guideline 4: | Standards of Practice in Clinical Electroencephalography. Minimal electroencephalographer qualifications (physician), EEG tech (not less than 6 months of supervised clinical experience), lab director has responsibility for overall policies. |
ACNS - Guideline 5: | Guidelines for Standard Electrode Position Nomenclature. 10-20 modified combinatorial 10-10 system. |
ACNS -Guideline 6: | A proposal for standard montages to be used in clinical EEG. |
ACNS -Guideline 7: | Guidelines for writing EEG reports. Provide minimum of information about the pt, (age, sex, etc.), test ID , then 3 principal parts: (A) Introduction, (B) Description of the record, and (C) Interpretation, including (a) impression (b) correlation. |
ACNS -Guideline 8: | Guidelines for recording clinical EEG on digital media. (See OSET). Commercial devices may be unreadable within a few years of storage. Newly emerging standards may make this less of a problem. |
ACNS -EEG Monitoring in Neonates: | For selected, long-term monitoring of high risk neonates of post-menstrual age less than 48 weeks (Since epileptic szs are difficult or accurately identify by visual inspection alone). Sens = 2-15 uV. |
What is the minimum number of channels allowed for a recording? | 8. |
How many leads are minimally required? | 21. |
How many montages are minimally required? | 3. |
Which montages are minimally required? | LB, TB, and Ref. |
