Tests Performed in our Sleep Center
Polysomnography or Overnight Sleep Study
This test is an overnight test used to help diagnose and evaluate sleep disorders. A PSG generally includes monitoring of the patient's airflow through the nose and mouth, respiratory effort, electrocardiogram (EKG), blood oxygen level, electroencephalogram (EEG), electro-oculogram (EOG), snoring, body position, and chin electromyogram (EMG).
Multiple Sleep Latency Test -MSLT
This is a series of naps given the day following a PSG which does not show evidence of sleep disorder. This test is used to determine the level of sleepiness or inability to stay awake.
Maintenance of Wakefulness Test-MWT
This is used to assess the severity of sleepiness in patients complaining of excessive daytime sleepiness. This test is performed during the day, and the patient is asked to stay in a darkened room and asked to relax and try to stay awake and avoid napping.
Actigraphy
This is the use of instruments sensitive to movement, typically worn on the wrist, to record activity over time. Activity levels correlate with sleep/wake patterns, pain level, mood, energy expenditure, fatigue/alertness and other quantifiable parameters.
