What To Bring To Your Appointment

  • Completed Patient Paperwork
  • Picture ID and/or Government ID
  • Insurance Card(s)
  • List of Current Medications (even herbal supplements)
  • Comfortable attire (t-shirts, shorts, gowns, pajamas)

Some patients may be more comfortable using their own pillows or blankets, so please feel free to bring anything from home to ensure a peaceful night’s sleep.

What To Expect At Your Appointment

What you need to do to prepare

For your appointment, please bring comfortable clothing, preferably what you would normally sleep in. Pajama pants, t-shirt or gowns are appropriate attire. Please note that we will be using a paste in order to apply the electrodes to your scalp. Patients with complex hairstyles, wigs or extensions may wish to remove these prior to coming in for the scheduled appointment. If you are on medications, take them as you usually do. Do not drink or eat anything that contains caffeine after 12:00 noon. You may be more comfortable bringing and using your own pillow. If you think you may have trouble sleeping in a different environment, ask your physician for a prescription sleep aid. Bring this aid with you to the sleep lab.

About your appointment

Your appointment has been made for you in conjunction with your primary insurance company requirements. As a private room has been reserved and a sleep technologist assigned, it is extremely important that you keep your appointment. Please do not bring any valuables with you to the sleep lab.  Accommodations can be made for spouses of family members at our facilities under special circumstances while patients are being scheduled, before the appointment night.

Multiple Sleep Latency Test (MSLT)

The Multiple Sleep Latency Test (MSLT) is a sleep disorder diagnostic tool. The test is based on the idea that the sleepier people are, the faster they will fall asleep. It can be used to test for narcolepsy, to distinguish between physical tiredness and true excessive daytime sleepiness, or to see if breathing disorder treatments are working. Its main purpose is to serve as an objective measure of sleepiness. The test consists of four or five, twenty-minute naps that are scheduled about two hours apart. The test is often done following an overnight sleep study. During the test things such as the patient’s brain waves, EEG, muscle activity and eye movements are monitored and recorded. The entire test normally takes about 7 hours.

Polysomnogram (PSG)

Polysomnogram (PSG) is a multi-channel (poly) recording (gram) during sleep (somno), resulting from a sleep test or polysomnography. A doctor may order a polysomnogram because the patient has a complaint such as daytime fatigue or sleepiness that may be from interrupted sleep. Typically, doctors order a polysomnogram to diagnose or rule out obstructive sleep apnea. Although the PSG can be done during the day or night, the vast majority of sleep studies are done at night, when most people sleep. Shift workers and people with circadian rhythm sleep disorders can be accommodated in our labs by having the test during other times of day. For the standard test the patient comes to a sleep lab in the early evening, and over the next 1-2 hours is introduced to the setting and “hooked up” so that multiple channels of data can be recorded when he/she falls asleep. A sleep technician will always be in attendance and is responsible for attaching the electrodes to the patient and monitoring the patient during the study.

Positive Airway Pressure (PAP) Titration

A positive airway pressure (PAP) machine is used mainly by patients for the treatment of sleep apnea at home. Obstructive sleep apnea occurs when the upper airway becomes narrow as the muscles relax during sleep. This reduces oxygen in the blood and causes arousal during sleep. The PAP machine stops this phenomenon by delivering a stream of compressed air via a hose to a nasal pillow, nasal mask or full-face mask, splinting the airway (keeping it open under air pressure) so that unobstructed breathing becomes possible, reducing and/or preventing apneas and hypopneas. This has the additional benefit of reducing or eliminating the extremely loud snoring that sometimes accompanies sleep apnea. PAP treatment can be highly effective in treatment of obstructive sleep apnea. For some patients, the improvement in the quality of sleep and quality of life due to PAP treatment will be noticed after a single night’s use. Often, the patient’s sleep partner also benefits from improved sleep quality, due to the elimination of the patient’s loud snoring. Given that sleep apnea is a chronic health issue and doesn’t go away, ongoing care is needed to maintain PAP therapy.
