Polysomnographic technologists assist physicians in performing sleep diagnostics that are required for diagnosis of sleep disorders.

The technologist simultaneously monitors:

• EEG (electroencephalography—brain waves)
• EOG (electro-occulography—eye movement)
• EMG (electromyography)
• ECG (electrocardiography—heart rhythm)
• Multiple breathing variables
• Blood oxygen and carbon dioxide levels

Technologists provide supportive services – related to the ongoing treatment of sleep-related problems – that include guidance on the use of devices for the treatment of breathing problems during sleep and helping individuals develop sleeping habits that promote good sleep hygiene.

PSG technologists are employed in Sleep Disorders Centers and labs, which may be located in medical centers, hospitals, or clinic/office settings.
