Troubleshooting and elimination of artifact in polysomnography.

A sleep technician who runs a sleep study without understanding the basis of the signals being acquired can spend a lot of time and energy trying to improve poor signal quality without success. Poor signal quality often results in an image that cannot be interpreted or is difficult to interpret, and extensive troubleshooting often results in a very disrupted sleep study. This article addresses trouble-shooting and elimination of artifact in polysomnography.
