Conquer your sleep disorders and get a good night's rest.

Having a hard time falling asleep? Do you wake up in the middle of the night, and then you find it difficult to get back to sleep? Or, maybe you snore too loudly, suffer from nightmares or walk in your sleep?

The specialists at Health Quest Sleep Medicine are dedicated to helping you unravel the mystery of why a good night's sleep has escaped you.   Many sleep disorders go undiagnosed for years, and can disrupt your health. For example, inadequate sleep can adversely impact heart, lung, and kidney conditions, immune function, sensitivity to pain, reaction time, mood, and brain function. Poor sleep is a big risk factor for depression and substance abuse.  Research has shown that not enough sleep can lead to weight gain.

At Health Quest Sleep Medicine, we perform overnight diagnostic sleep studies, titration studies with CPAP and BIPAP, day study testing, split night studies, MSLT and MWT testing, and home sleep testing. Our Centers are equipped to study children as young as five years old at our Putnam and Fishkill locations; and as young as three years old at our Northern Dutchess Hospital. Each center is staffed with a board-certified sleep physician, who will use these diagnostic studies to customize a sleep solution that's right for you. Consultations with a board-certified sleep physician is available upon request.

Sleep Conditions

We evaluate and treat a wide range of sleep conditions and issues:

  • Insomnia is the inability to get to sleep, stay asleep or wake at the right time to assure proper rest.
  • Excessive snoring refers to the harsh or hoarse sounds that result from partially blocked airways and disrupt sleep.
  • Obstructive sleep apnea (OAS) is a common, but serious and potentially life-threatening breathing disorder marked by lack of air flow through the night.
  • Narcolepsy is a chronic neurological disorder affecting the nervous system, characterized by extreme daytime sleepiness and the sudden need to sleep during the day, or, alternately, a sudden collapse in which you appear unconscious but remain awake and alert. Parasomnias is a set of disorders that include sleepwalking, bed-wetting (enuresis), nightmares, waking up confused, sleep paralysis and other abnormal behavior during sleep.
  • Restless legs syndrome is a movement disorder characterized by throbbing and other unpleasant sensations in the legs, along with an uncontrollable urge to move them, especially at night after going to bed.
  • REM (rapid eye movement) sleep behavior disorder is the physical acting out of vivid, often unpleasant dreams with vocal sounds and sudden, often violent arm and leg movements during REM sleep

What You Experience During a Sleep Study

When it comes to being tested, you may be pleasantly surprised. Imagine a night at home — or better. Our sleep studies are conducted during an overnight stay in one of our comfortable, modern, quiet, hotel-like rooms. Each room is equipped with a flat-screen television and private bathroom and can accommodate bariatric, special needs and pediatric patients three years of age or older.

After you arrive at the center on the evening of your study, your technician will take about an hour to hook you up to the study monitors by attaching electrodes using washable gel to various parts of your body (a painless procedure). After, you are free to relax, read, or watch television until you are ready to go to sleep at your normal bedtime. In the morning, we will awaken you around 5 a.m. and it will take us about 20 minutes to remove the electrodes. Then, you'll be free to shower, dress, enjoy a complimentary light breakfast and go about your day.

Patient Registration Packet

Prior to your overnight stay, please download the files below, then complete and bring with you.


What You Need to Bring

While you will be at the sleep facility for one night only, there are certain things you must bring:

  • Medications: You must bring any medications, including supplements that you regularly take. Please bring only what you need for one night, and in its original medication container. Note that medications are not dispensed at the sleep facility. Also, bring a list of other medications you take.
  • Your health insurance card and a photo ID. We will not be able to conduct your study without a photo ID.
  • Pajamas: You must wear two-piece pajamas because one-piece pajamas do not allow for the electrodes and sensors to be easily attached.
  • Personal toiletries: Please bring your own toothpaste, toothbrush, shampoo, conditioner, hair dryer, comb, etc., and a change of clothes for the next day.
  • Fun stuff: Don't forget to bring a favorite pillow, book, or white noise device. Children should bring favorite blankets, stuffed animals, or toys.  

 Sleep Studies for Children

Sleep disorders are common among children, including sleep apnea, difficulty falling or staying asleep, and the inability to sleep at desired times. Narcolepsy typically begins in adolescence but may affect younger children.

We work closely with families to ensure the best experience for your child. For the duration of the study, we request that all minors (under 18) be accompanied by a parent or caregiver. That means you will be staying overnight with your child in the same room. A recliner and bedding accommodations will be provided for your comfort.

Once you arrive, before the study begins, our technologists will carefully explain the equipment and procedure to you and your child and answer questions. To alleviate any anxieties, we may invite you to "try on an electrode" if necessary and show your child that the process does not hurt at all. Our goal is to help your child feel as comfortable and relaxed as possible while ensuring proper placement of the sensors.

Whenever possible, we will adhere to your child's normal bedtime. Please be sure to bring your child's favorite bed time blanket, pillow, or stuffed animal to make him or her feel as comfortable as possible.

How We Test

The overnight sleep study test we conduct is called a polysomnography (PSG), which can both diagnose your sleep disorder and determine the effectiveness of the treatment. During the night, via advanced diagnostic technology, your sleep patterns will be recorded, including activities of your heart, lungs, brain, muscle movements, air flow and oxygen levels in the blood. At any point, you can press your call bell and our technicians will come in to assist you. However, we encourage you to try to sleep through the night.

Once your study is complete, your data is evaluated to determine if you are experiencing sleep apnea or some other less common sleep disorder. Within 8 to 10 business days, a completed report containing recommendations by the Center's Medical Director will then be sent to your  physician,  Please be sure to follow up with your physician to review the results, and decide on the next step.

Treatment Recommendations may include:

  • Behavior modification therapy offers psychological and lifeclass tips to create a more sleep-inducing environment.
  • Medication includes pharmaceuticals and/or other supplements to ensure a good night's rest.
  • Surgery on the upper airway, such as tonsil and/or adenoidectomies
  • Dental devices are similar to removable mouth guards that patients wear at night to adjust their palate and keep the airway open.
  • Assistive breathing devices such as CPAP (Continuous Positive Airway Pressure) and BiPAP (BiLevel Positive Airway Pressure), which provide patients with airflow through a mask from a tube that is connected to a small machine that would sit on your nightstand  The device is used while sleeping.
  • Positional therapy offers instructions on how to sleep in a certain position to better regulate airflow.


A prescription from your physician is required for a sleep study. Please contact us to help you determine if a sleep study is covered by your insurance.
