If sweat artifact is severely obscuring the EEG, what is the FIRST step the technologist should take?

• A. Place a rolled-up towel behind the head
• B. Turn LFF to 5 Hz
• C. Turn sensitivity down
• D. Cool the patient down by removing the blanket and fanning the patient

Answer: (D)

When sweat artifact significantly obscures the EEG, the first step the technologist should take is to cool the patient down by removing the blanket and using a fan to assist in this process. This approach directly addresses the source of the artifact. Sweat can interfere with the quality of an EEG recording as it creates additional electrical noise, which can create misleading or false readings. By cooling the patient, you can help minimize sweating, thereby reducing the artifact and improving the clarity of the EEG signals. This strategy is vital because the goal is to maintain the integrity of the EEG data, and managing the patient's temperature can have an immediate positive effect on reducing extracellular noise. Once the sweat artifact is minimized, the technologist can then consider other adjustments in the technical settings if further refinement is necessary.
