Q: How long is a sleep study?

A: The process typically takes 6 to 8 hours. While most sleep studies occur at night, they are available during the day for patients who routinely work a third shift. Gwinnett Sleep’s day services include the Multiple Sleep Latency Test and Maintenance of Wakefulness Test.

Q: Where do Gwinnett Sleep’s sleep studies take place?

A: The sleep studies are performed in private rooms that are comfortable and quiet. Sleep rooms at Gwinnett Sleep are equipped with Sleep Number beds or Tempur-Pedic mattresses with reclining functions, as well as televisions with Direct TV. Full bathrooms with showers are also available.

Q: How is a sleep study performed?

A: Sleep studies are performed by applying small metal discs (electrodes) to the head and skin with an adhesive. Breathing is measured by flexible elastic belts positioned on the chest and abdomen. Blood oxygen saturation is measured by a clip on the index finger or earlobe (pulse oximeter). This procedure is painless and designed to be as pleasant as possible.

Q: How long will it take to receive sleep study test results?

A: After your study is performed, we will evaluate your results and you will receive a final report within five business days. We will then develop a custom treatment plan and schedule any required studies, tests, or follow-ups.
