area in red and functions

Frontal lobe; functions are thinking, speaking, memory and movement

area in blue and functions

parietal lobe; functions are language, touch, taste and smell

area in purple and functions

temporal lobe; functions are hearing, learning, feelings and fear

area in pink and functions

brain stem; functions are breathing, heart rate, temperature and blood pressure

What is EEG?

Electroencephalogram

EMU/PMU

patients are admitted for evaluation and management of diagnosed epilepsy

supplies used to apply and set up EEG

jackbox or tbar, electrodes, EKG wires/stickers, wax pencil, air hose, gauze, collodion, nuprep skin gel, tape measure, conductive creme and syringe, conductive paste, acetone, kurlix and a portable

How do we find patient history and where do the EEG results go?

EPIC

Neuroworkbench

used to run EEG to record and transfer brainwave data

Ebase

billing for epilepsy, tech forms for the patient

Persyst

able to detect seizures/help identify potential seizure activity

What are the 4 landmarks for marking and measuring?

nasion, inion, left and right preauricular
