Sleep Evaluation

We perform various types of sleep evaluations to determine the type, breadth, and cause of your sleep disorder. These tests all take place while you sleep. Some, like a home sleep test , you take home with you and go to bed as you normally would. Others require a more comprehensive evaluation which takes place at a facility called a Sleep Lab where you spend the night in a comfortable room off premises. These tests are safe, completely painless, and measure indicators like brain activity, heart rate, breathing airflow, body movements, and more. We then review that data and provide an appropriate treatment plan.

  • Polysomnographic Study

    Polysomnography is a test that records parameters during sleep, which includes EEG (recording of electrical brain waves) and EMG (muscle movements), eye movements, oxygen level of blood, air movements to and from the lung, carbon dioxide levels, and cardiogram. These measurements allow for assessment of sleep, wakefulness, arousals, breathing, heart function, and brain and nerve function. A polysomnography test is performed in a specialized sleep laboratory. The patient sleeps in a comfortable, home-like bedroom. A series of painless electricity conducting pads are placed on the head, face, chest, and legs, which measure electric signals of the brain, respiration, heart, lungs, and muscles. There is also a night vision video camera to record actions and movements. While some patients may think they will be unable to sleep with all the measurement instruments, the rooms and beds are so comfortable that this has rarely been a problem.

  • Multiple Sleep Latency Test

    Multiple Sleep Latency Test (MSLT) is performed during the day and is designed to objectively assess and measure complaints of tiredness, fatigue, and sleepiness during the day. In MSLT, daytime naps are analyzed. Every two hours, the patient is given the opportunity to nap for 20 minutes using the same instruments as the polysomnograph. The test is performed over 10 to 12 hours, so four to five naps can be evaluated. In between naps, the patient is comfortable in a living room like comfort-room, where the patient may watch TV, use a computer with internet access, read, or do other activities to occupy their time.

  • Actigraphy

    A watch-like monitoring device is worn on the wrist in order to find out when the patient sleeps and wakes up. This test is for patients that have Phase Delay or irregular sleep. The device captures periods of wake and sleep during a 24-hour cycle over the course of several days.

  • Home Sleep Studies

    Under certain circumstances, when the clinical picture is not complicated, and extensive observation is not needed, a simplified version of the sleep study may be performed at home with portable monitoring as a screening tool. However, if the test is negative, a full in-lab sleep test may become necessary.

    The home sleep test is an abbreviated version of a polysomnography with a limited number of electrodes, which essentially only monitor respiration and oxygenation. This test is primarily used for patients who have a high index of suspicion for severe sleep apnea. This test is performed mainly to confirm sleep apnea if it's highly indicated during an office exam.
