Placement of leads for the sleep study
This chapter focuses on how to place different sensors during a sleep study. It discuses place sensors at correct position during a sleep study. The chapter analyses get the optimal output from the sensors. It discuses why sensors are placed at that very position as suggested in manual from American Academy of Sleep Medicine. Bilateral placement of electrodes helps to determine various sleep stages, even when one or more electrodes on one side of the scalp develop any artifact or fall during the sleep study. For recording an Electroencephalogram (EEG), electrodes are placed bilaterally in the frontal, central and occipital positions. Electromyogram is placed at two sites in the body. First is to measure the tone of the mentalis-submentalis muscle, which helps in scoring of the sleep stage and another one to measure the periodic limb movements during sleep (PLMS).
