Monitoring your sleep during an overnight sleep study is usually the only way to determine whether a sleeping disorder exists. A sleep study records functions of the lungs, heart and other parts of the body. Testing is painless, risk-free and usually takes one full night.

Our test methods include:

  • Polysomnogram (NPSG) is a sleep study that evaluates and records the patient's physical state during sleep periods. Each study lasts about nine hours, including time to prepare the monitors. Patients generally arrive two hours before their usual bedtime.
  • Multiple Sleep Latency Test (MSLT) is a daytime nap study to measure degree of daytime sleepiness. This test consists of a series of up to five naps during the day at two-hour intervals.
  • Out of Center Sleep Testing (OCST) may be used as an alternative to polysomnography for the diagnosis of obstructive sleep apnea (OSA) when there is a high pretest probability of moderate to severe OSA. This sleep study is done in the comfort of your own home, rather than in a clinical setting, and tests for sleep apnea and snoring. If a more in-depth study is needed then a Polysomnogram is the best option.


It is estimated that between 50 and 70 million Americans suffer from serious chronic and intermittent sleep disorders that undermine their sleep quality and their health. Some of the more common include:

  • Insomnia: The complaint of an inability to fall asleep, stay asleep, or awaking too early. This may be caused by poor sleep habits, alcohol, medications, and stress.
  • Sleep Apnea: An obstruction of the upper airway that results in breathing pauses and sleep disruption. This is a serious and potentially life-threatening condition that causes people to stop breathing many times while they sleep. People suffering from sleep apnea are more likely to have a higher risk of hypertension and strokes, as well as car accidents due to excessive daytime sleepiness.
  • Narcolepsy: This ailment causes people to experience excessive daytime sleepiness and uncontrollable episodes of sleep. Narcolepsy is typically associated sudden loss of muscle tone, vivid hallucinations occurring just before sleep, and the transient sensation of being paralyzed during the transition between sleep and wakefulness.
  • Periodic Limb Movement Disorder (PLMD): Periodic episodes of leg jerks or movements that disrupt sleep.
