What is a Sleep Study or Polysomnography?
Polysomnography is the continuous and simultaneous monitoring and recording of various physiological and pathophysiological parameters of sleep with physician review and report. It must include sleep staging, EEG (electroencephalogram), EOG (electro-oculogram) and EMG (submental electromyogram). It must also include the additional parameters of sleep: airflow, respiratory effort and oxygen saturation. The study may be performed as either a whole night study for diagnosis or as a split night study to diagnose and initially evaluate treatment.
