This paper describes basic electrical concepts, the op-eration of differential amplifiers, the use of filters and filtering, aspects unique to digital polysomnography, com-mon artifacts encountered during recordings, and recent changes in technical rules for the scoring of polysomnog-raphy studies that were established by the American Acad-emy o...
polysomnographic evaluation is one of the tools used by physicians that can result in a specific diagnosis of a sleep disorder that might otherwise remain obscure. Polysomnography is recommended for the clinical suspicion of sleep disordered breathing with any of the following conditions: heart disease congestive heart failure

The standard DC amplifier used in polysomnography is a single-ended amplifier, which amplifies the difference between a single input and ground. DC amplifiers have no LFF or TC filter to filter out lower frequency signals. Therefore, the output reflects undistorted input signals.

Abstract. Polysomnography refers to a systematic process used to collect physiologic parameters during sleep. A polysomnogram (PSG) is a procedure that utilizes electroencephalogram, electro-oculogram, electromyogram, electrocardiogram, and pulse oximetry, as well as airflow and respiratory effort, to evaluate for underlying causes of sleep ...
