Sleep Center in Staten Island, NY
Our sleep professionals use state-of-the-art equipment for diagnostic testing of patients with or suspected of having sleep disorders. The Sleep Disorder Center is fully equipped to evaluate and diagnose patients. Sleep studies provide information useful in uncovering hidden health issues such as:
- Obstructive sleep apnea
- Periodic limb movements
- Restless leg syndrome
- REM behavior disorder
- Parasomnias (sleep walking) and other sleep disturbances
Types of Sleep Studies
Sleep studies are painless procedures done to evaluate sleep and diagnose sleep disorders. These studies are conducted using a Polysomnogram (PSG), which is a test that electronically transmits and records such factors as breathing, heart rate, heart rhythm, brain activity, and eye movement. During the PSG, electrodes (band aid-like patches with sensors) will be placed on the face, scalp, chest, and limbs. These sensors will record such things as brain activity and the amount of oxygen in the blood.
There are four types of sleep studies:
- Multiple Sleep Latency Test (MSLT) - This test is normally done two hours after PSG, and it is typically conducted during the day. The patient will be asked to fall asleep in a dark room where a nurse will monitor the stages of sleep. Patients will be asked to do this four or five times throughout the day with 2-hour breaks in between. This test will diagnose disorders like narcolepsy, idiopathic, and hypersomnia.
- Maintenance of Wakefulness Test - After a PSG, patients are asked to sit quietly in a comfortable chair and try to stay awake for a period of time. This is typically done in four trials that last 40 minutes with 2-hour breaks in between.
- Home-Based Portable Monitor Test - The sleep center will send the patient home with specialized equipment that must be set up before sleep.
- Actigraph - This small device is worn like a wristwatch and measures the patient's behavior over a 3–14 day/night period. The doctor may also request that the patient keeps a sleep diary.
What to Expect
The Center will provide an overnight stay in a private and comfortable room in our facility. Not far from the bedroom will be a central monitoring area where the staff will watch and evaluate sleeping patients throughout the night. The technician and nurse will monitor the heart rhythm, brain waves, and airflow using the polysomnogram. This equipment may appear unnatural at first; however, most people tend to fall asleep quite easily. Once the sleep study is complete, we will then send a full report, along with our physician's interpretation, to the patient's referring or primary care physician within 96 hours.
Once electrodes are placed on the face and scalp, belts will go around the chest and abdomen to measure breathing. The technician will also put a bandage-like probe, called an oximeter, around the patient's finger. This device will measure the amount of oxygen in the blood. Other equipment and devices we use in the center are:
- EEG (Electroencephalogram) - Measures and records abnormal brain wave activity.
- EMG (Electromyogram) - Assesses the health of motor neurons and activities like teeth grinding and face twitches. It can also detect REM.
- EOG (Electrooculogram) - Records eye movement that helps to determine sleep stages.
- EKG (Electrocardiogram) - Measures the electrical activity of the heart.
- Nasal Airflow Sensor - Records airflow.
- Snore Microphone - Transmits snoring sounds.
