Before the Recording
This must be reviewed from the MD before starting an EEG.
What is the order?
This calibration is performed at the beginning and end of every EEG.
What is square wave calibration?
This must always be done to the electrodes and equipment after finishing.
What is cleaning and disinfecting?
According to ACNS guidelines, how many channels are required at a minimum?
What is 16 channels?
These patient details must be documented (name two).
What are name, age, date, MRN, medications, or history?
These are applied using the 10-20 system before starting the recording.
What are electrodes?
These procedures (like HV, photic, and sleep) are done to activate brain activity.
What are activation procedures?
This must be completed in the EMR before archiving the study.
What is documentation/paperwork?
Needles are not recommended for these kinds of EEG studies.
What are routine EEG studies?
The standard filter settings are this range.
What is 1–70 Hz?
Name one thing you must explain to the patient before starting the EEG.
What is the purpose of the test / how long it will take?
This value must remain below 5kΩ for good electrode contact.
What is impedance?
Besides cleaning the patient, you must also do this to your work area.
What is clean up/disinfect your work area?
The starting sensitivity should be set between these values.
What is 5–10 µV/mm?
The minimum length of an EEG recording must be this long.
What is 20 minutes?
These are the two main things you must gather and prepare before applying electrodes.
What are supplies and the recording room?
This is the name of the procedure performed at the start of the recording to verify amplifier integrity
What is a Biocal?
After the study is completed, this step ensures the recording is permanently stored for physician review.
What is archiving the study?
Routine EEG requires application of this many electrodes (plus ground).
What is 21 electrodes (10–20 system)?
This is the required paper speed for a routine EEG
What is 30 mm/sec?
This type of patient information must always be obtained before starting an EEG.
What is a complete patient history?
Besides bipolar montages, this type of montage must also be included during the EEG recording.
What is a referential montage?
These three things must always be done after completing a recording to maintain patient and equipment safety.
What are cleaning the patient, disinfecting equipment, and cleaning the work area?
This is the required length of hyperventilation during an activation procedure, plus the post-HV period.
What is 3 minutes with 1 minute post-HV?
This should never be used unless absolutely necessary, since it can distort the EEG.
What is the 60 Hz (notch) filter?
