The best way to eliminate artifact is by:

• A. Adjusting the filters
• B. Going to the problem source and replacing and reapplying the affecting leads
• C. Doing nothing, as they tend to resolve on their own
• D. Stopping the study and reapplying all the leads

Answer: (B)

Artifacts in sleep study recordings usually come from the skin–electrode interface, such as poor contact or high impedance. The most reliable way to eliminate artifact is to address the source by replacing and reapplying the affected leads, ensuring clean skin prep and secure, low-impedance contact. When leads are properly placed and impedance is checked and kept low, many common artifacts from electrode pops, movement, or poor adhesion disappear, yielding clearer signals. Relying on filters to fix artifact can distort the EEG and does not remove the underlying problem, so it’s not as effective as correcting the electrode issue. Doing nothing won’t improve the recording, and stopping the study to reapply all leads is unnecessarily disruptive if only certain leads are at fault. The practical approach is to inspect and fix or replace the offending leads, recheck impedance, and resecure them so the recording remains stable throughout the study.
