Sleep Lab

Sleep is important for renewing your mental and physical health. However, 40 million Americans fail to get a good night’s sleep, according to the National Institutes of Health. Some may have difficulty sleeping and not even be aware of it because, while they are able to fall asleep, they may not experience truly restful sleep.

Symptoms of a sleep disorder vary widely but can include one or more of the following:

  • Snoring
  • Gasping or choking during sleep
  • Morning headaches
  • Daytime sleepiness
  • Trouble going to sleep or waking during the night
  • Falling asleep at unusual times

Our sleep lab provides comprehensive evaluation and treatment of the full spectrum of sleep disorders through three different sleep studies. If you suffer from one of the symptoms listed above, you need to speak to your primary physician to determine if you need to have an overnight sleep study. All of our sleep studies are reviewed by a board-certified sleep medicine physician to determine if treatment is required. He or she will work in conjunction with your physician or specialist to develop the best course of care for your individual needs.

We offer the following sleep tests:

Routine Sleep Study/NPSG

This test is used to determine whether a patient has Obstructive Sleep Apnea, Restless Leg Syndrome or Periodic Limb Movement Syndrome. Six hours of sleep are typically needed to complete this test.

Continuous Positive Airway Pressure/CPAP 

A CPAP test allows the technician to fit a patient with a proper CPAP device and set the pressure levels to determine the lowest pressure needed. This study is done as a follow up to a Routine Sleep Study that shows the necessity for CPAP.

Split Study

A Split Study assesses the patient for Obstructive Sleep Apnea during the first half of the evaluation as is done in a Routine Sleep Study. However the remainder of the test is done with the application of CPAP. The test must meet several parameters to properly assess the necessity of CPAP. If those are not clearly defined the patient may need to return for a full night CPAP Titration.

Multiple Sleep Latency Test

The multiple sleep latency test (MSLT) evaluates excessive daytime sleepiness by measuring how quickly a patient falls asleep in a quiet environment during the day. Also known as a daytime nap study, the MSLT is the standard tool used to diagnose narcolepsy and idiopathic hypersomnia.

Home Sleep Test

The Sleep Lab also offers the home sleep test which is taken in the comfort of one's own home. With a home sleep test the user will typically come to the sleep lab the day of the test to pick up the necessary equipment. At that time we provide a thorough demonstration on how to use the machine properly to enable the most effective results. The testing is performed by the user and the data is stored on the equipment.  The data is uploaded by the sleep lab upon return of the equipment the following day.

Most insurance plans, including Medicare, are accepted.
