Sleep Studies

Sleep Evaluation Center

What is a Sleep Study?

A Polysomnography is a sleep study, during which we conduct a very thorough evaluation of your sleep patterns in order to pinpoint problem areas. This will aid in diagnosis and treatment. This is a very safe procedure requiring an overnight stay in our facility. Our rooms are private and designed for comfort and to make you feel at home. During the study a patient is monitored closely and a variety of data will be obtained.

Our Sleep Lab

Our sleep lab is equipped with state-of-the-art technology and is staffed by registered technicians. It has been custom designed to create a comfortable, like-home atmosphere.

Our goal at Hackensack Sleep Evaluation Center is to make your experience as pleasant as possible. You may bring anything you need to sleep and to make you feel more at home, such as DVDs, stuffed animals, your own pillow.

Our beds are comfortable and fully motorized so you can raise your head, feet, or both so you can enjoy an infinite number of ergonomic rest positions. There is cable TV in each private room for your entertainment while waiting to begin your test.

To provide each patient with maximum privacy and comfort, the sleep center is divided into sections. The Executive Section has the most advanced and luxurious services available. It is equipped with all the necessary business and communication tools for busy executives during their stay.

To get accurate results from the test, we cannot allow patients to have someone sleep in the bed with them. If necessary, you may have a bed partner sleep in the same room with you.  A separate comfortable sleeper chair is available.

Types of Sleep Studies

Polysomnogram

A polysomnogram is a sleep study which records a full night’s sleep, including your brain waves, heartbeat, breathing, and the movement of your limbs while sleeping. A polysomnogram usually includes:

  • Electroencephalogram (EEG) which monitors brain waves
  • Electro-oculogram (EOG) which monitors eye movements
  • Electromyogram (EMG) monitors muscle activity
  • Measurement of airflow through the nose and mouth
  • Measurement of chest and abdominal movement
  • Audio recording of snoring activity
  • Video monitoring the patient during the sleep study

CPAP Study

A CPAP Study establishes the correct equipment levels for CPAP therapy used to treat sleep apnea. CPAP stands for continuous positive airway pressure. If a patient shows signs of severe sleep apnea during their overnight sleep study, a CPAP study may be done the same night.  This will determine the level of air pressure needed to prevent the collapse of the upper airway due to sleep apnea.

CPAP machines are designed to maintain enough air pressure to keep a patient’s airway open and allow them to sleep.

BiPAP

A BiPAP machine is a breathing apparatus that helps patients get more air into their lungs. BiPAP stands for bilevel positive airway pressure. A BiPAP machine allows one pressure to be set for inhaling and another for exhaling. A sleep physician determines whether or not a patient needs a CPAP or a BiPAP based on the type of sleep apnea and its severity. These machines are especially helpful for patients with neuromuscular disease, congestive heart failure, and lung disorders. Some BiPAP machines even adjust therapy levels while the patient sleeps to ensure they are receiving optimum air pressure for a comfortable, successful sleep experience.

MSLT

A Multiple Sleep Latency Test or MSLT is performed primarily to measure sleep latency which is basically how long it takes you to fall asleep. There is a wide range of what would be considered normal sleep latencies. Sleep physicians know when this test is necessary and are able to gather needed information to diagnose and treat patients. MSLTs are especially helpful in diagnosing excessive daytime sleepiness and narcolepsy.

An MSLT, if required, is performed the day after undergoing a polysomnogram. During the test you will have scheduled naps at intervals throughout the day that are monitored by a sleep technician. Many physiological parameters are also monitored while you sleep. These include breathing, oxygen levels, muscle tone, and eye and extremity movements. An EEG and EKG are also done during this test.

Frequently Asked Questions

Most patients will stay in the lab for a total of 10-11 hours. This time not only includes sleeping, but filling out paperwork and being prepped for the study.

You should bring whatever you need to sleep. Our goal is to make your experience during your in-lab test as comfortable and pleasant as possible. We invite you to bring DVDs, stuffed animals, your own pillows, or any other things that typically help you sleep (no pets please).
