Preparing For A Sleep Study

About a Home Sleep Apnea Test

Do not have any caffeine in the afternoon or evening before an overnight sleep study. This includes coffee, tea, cola, and chocolate. Also avoid drinking any alcohol. You do not want any substance to affect your sleep. Try not to take any naps that day. Before going to the sleep center, wash your hair with shampoo only. Dry your hair and do not apply any hair sprays, oils or gels. If used, they could interfere with the sensors during the study.

Pack an overnight bag to take with you to the center. Bring comfortable pajamas and a change of clothes for the morning. Include the same items you would take for a stay at a hotel. You may also want to bring your own pillow. Bring your medications if you will need to take them while you are away from home. If you have special needs or concerns, tell the sleep center staff ahead of time. They will do all they can to help you feel relaxed and at ease.

What Is The Ahi Scale

The AHI scale is a measurement tool that represents the amount of times that a person stops breathing, or almost stops breathing per hour. The goal of using the AHI scale is to measure the severity of your sleep apnea. The AHI is the sum of the number of apneas plus the number of hypopneas that occur, on average, each hour.

Can I Do A Sleep Study At Home

Home sleep studies are currently only used to evaluate for obstructive sleep apnea . Home sleep apnea tests are less effective at detecting OSA than polysomnography, so the American Academy of Sleep Medicine recommends that they only be used when moderate or severe OSA is suspected and when other health conditions are not present. The AASM also advises that diagnosis and treatment of sleep apnea should not be based solely on the results of an at-home sleep study.

However, home sleep apnea tests are more convenient, may be more affordable, and you may sleep better in your own bed than at a clinic. If your doctor recommends polysomnography to detect sleep apnea, you can ask whether a home study may be an appropriate alternative.

What Is Sleep Apnea

Sleep apnea is a serious sleep disorder. People who have sleep apnea stop breathing for 10 to 30 seconds at a time while they are sleeping. These short stops in breathing can happen up to 400 times every night. If you have sleep apnea, periods of not breathing can disturb your sleep .

Men, people who are overweight, and people who are older than 40 years of age are more likely to have sleep apnea. However, it can affect anyone at any age.

What Happens During A Nap Study

Sleep Apnea Body Basics

Sometimes you may need to stay after your sleep study to take a daytime nap study. This study is called a Multiple Sleep Latency Test . It is used to see how quickly you fall asleep in quiet situations during the day. The MSLT is the standard tool used to evaluate people who are thought to have narcolepsy. It may also be used to see if a person has hypersomnia. It begins between 1.5 and three hours after you wake up from the overnight sleep study. It consists of five nap opportunities with breaks lasting for two hours in between them. A shorter four-nap study may also be used. Your sleep patterns are monitored with most of the same recording equipment used the night before. The time it takes you to fall asleep will be measured. The kind of sleep you get during each nap will also be recorded. This is a valuable tool to help determine why someone is very sleepy during the day.

Be sure to plan ahead for a longer stay when you are scheduled for a nap study. You can call the center in advance to find out about breakfast and lunch plans. They can also let you know about what time the MSLT will be finished. Between nap trials, you will have to stay out of bed and occupy yourself so that you remain awake. You may want to bring things with you to work on or to entertain yourself. You can also ask about watching TV or videos between naps.

    This is the question that people ask most often before a sleep study. Many people expect the sleep center to be cold and harshly lit. They imagine that their room will be like a small closet, filled with computers and beeping machines. But most sleep centers make you feel relaxed and comfortable. Their rooms are nicely decorated and may remind you of a hotel. It is so quiet and peaceful that most patients fall asleep quickly. It is expected that you might not sleep quite as well as you do at home. This should not hinder the study or affect the results.

    How Does A Sleep Study Work

      Sleep disorders cause many troubling symptoms that can affect ones mood, energy level, and overall health . Unfortunately, sleep disorders are notoriously underdiagnosed because they often develop gradually over time and have symptoms that are difficult to recognize.

      Accurate diagnosis is necessary to enable effective treatment for sleep disorders. A sleep study provides valuable insight into the causes of a persons symptoms including which, if any, sleep disorder is present. Sleep studies are also used in people diagnosed with sleep disorders to monitor their response to treatment.

      How Much Does A Home Sleep Study Cost

      Depending on the location of the testing center and your health insurance coverage, a traditional in-lab sleep study can cost anywhere between $600 and $5,000, though it can even exceed this upper limit in some cases. The average cost of an in-lab sleep study is around $1,000 to $2,000, and most insurance companiesincluding Medicarewill cover the bulk of this expense.

      Home sleep studies are becoming increasingly popular because they cost much less than tests conducted in a sleep lab and can be completed in the comfort of your own home. A home sleep test can cost as little as $125 depending on your current health insurance coverage.

      Whether or not your insurance will cover a lab sleep study will depend on your plan and whether youve already met your deductible for the year. Its also important to make sure you go with a sleep clinic thats in your insurance network. On the other hand, a home sleep study is much cheaper to participate in, and even if your insurance doesnt cover it, the out-of-pocket expenses for an at-home test are always cheaper than the sleep clinic option.

      During your overnight sleep study and through the use of the aforementioned sensors and channels, yoursleep technology technicians and physicians gain a better understanding of the quality and stages of your sleep. There are four sleep stages that a person typically goes through and each is important individually to the process.

      Sleep Stage 1

      This stage is where you transition from being awake to falling asleep. Its considered the dozing stage where you will display some slow eye rolling movements. You spend around two to five percent of your total sleeping time in this stage.

      Sleep Stage 2

      You begin to display larger brain waves in this stage and a lack of eye movement. This is the stage that is believed to be the beginning of consolidated sleep. The brain waves you form during this stage are known as K-complexes and sleep spindles with both showing a certain pattern of EEG activity. You spend around 45 to 55 percent of your total sleeping time in this stage.

      Sleep Stage 3

      During this stage, it will be hard to arouse you. You will display slow and large delta waves on the PSG.You may feel disoriented and groggy if woken.Around 20-25 percent of your total sleeping time is spent in this stage.

      What Is A Home Sleep Apnea Test

      A home sleep apnea test provides a medical provider with information to diagnose sleep apnea. It allows you to sleep at home wearing equipment that collects information about how you breathe during sleep. You will usually set up the testing equipment yourself.

      There are a variety of devices that have different sensors and equipment. These devices measure your breathing and blood oxygen level. Some also may measure your heart rate or other information about your body.

      A medical provider may recommend a home sleep apnea test if:

      • It is highly likely that you have moderate to severe sleep apnea
      • You have no significant medical conditions other than the suspected sleep apnea

      You should not have a home sleep apnea test if:

      • You do not have a high risk of sleep apnea
      • Your doctor suspects that you have another sleep disorder
      • You have certain medical conditions including pulmonary diseases, neuromuscular diseases or congestive heart failure
      • It is physically difficult for you to administer the test at home

      In these cases, your doctor may recommend a sleep study instead of a home sleep apnea test. A sleep study provides the most complete evaluation of your sleep.

      Living With Sleep Apnea

      Sleep apnea can cause serious problems if it isnt treated. Your risk of high blood pressure, heart failure, and stroke is higher if you have serious sleep apnea that goes untreated. You are also more likely to have traffic accidents if you drive while youre sleepy. If you have sleep apnea, it is very important to get treatment.

      My Night In The Lab: What A Sleep Study Really Feels Like

      Eric Fields, an attorney living in Hartsdale, N.Y., finally gets answers about his poor sleep and disruptive snoring

      After his sleep study, Eric was surprised to hear how loud his snoring really was.My wife has trouble sleeping because of snoring, irregular breathing, and teeth grinding: mine. I’ve been reluctant to address my problems, though I’m often tired due to poor-quality sleep I sometimes doze on the couch like my dad did when I was growing up. Recently I decided to get help after reading that untreated sleep conditions can cause heart disease. Plus, I don’t want to get banished from the bedroom.

      The initial appointmentI visited a certified sleep center in New York City, where my new doctor, Omar Burschtin, MD, looked into my mouth and told me I have a floppy palate, which can cause snoring. My wife had written down a description of my nighttime noises ahead of time, because she knew I wouldn’t be able to explain them myself. Here’s what she wrote: “When you are asleep and lying on your back, sometimes you make a loud snoring noise that tapers off to a quieter snoring noise with subsequent breaths. Eventually, you seem like you are barely breathing in any air at all, your breaths are so short. Then you make a quick snorting noise that seems to wake you a little because it makes you shift positions.”

      • EEG to measure and record brain wave activity
      • EMG to record muscle activity such as face twitches, teeth grinding, and leg movements, and to look for REM stage sleep. During REM sleep, intense dreams often happen as the brain has heightened activity.
      • EOG to record eye movements. These movements are important in determining the different sleep stages, particularly REM stage sleep.
      • EKG to record heart rate and rhythm
      • Nasal airflow sensor to record airflow
      • Snore microphone to record snoring activity

      How Should We Prepare For A Sleep Study

      Your child:

      • should get a normal night’s sleep the night before the sleep study
      • can take medicines as usual
      • should not have any caffeine
      • should not nap during the day of the sleep study

      Beckman Coulter Announced Today The Positive Results Of A Clinical Trial Suggesting That Blood Tests May Offer Key Benefits In The Initial Screening For Obstructive Sleep Apnea The Study Which Involved 264 Male Adult Patients From Six Institutions Revealed That Screening For Changes In Three Specific Biomarkers May Be Useful In Helping To Identify The Often

      Sleep apnea affects an estimated 100 million adults worldwide.

      The results of the pivotal study were published in the peer-reviewed journal, Nature and Science of Sleep, with the anticipation that use of these objective blood tests will improve screening accuracy and timely diagnosis as well as patient management.

      Beckman Coulter is the only supplier to currently offer this panel of three assays on fully automated platforms. Hemoglobin A1c and C-reactive protein are chemistry tests on the Synchron and AU systems while erythropoietin is on the DxI and Access 2 immunoassay systems.

      Approximately 34% of men and 17% of women experience sleep apnea, a common disorder that is characterized by brief patterns of interrupted breathing during sleep. Obstructive sleep apnea occurs when the throat muscles relax and the airway becomes obstructed. The prevalence of sleep apnea is on the rise due to an aging population and increasing obesity rates however, 90% of individuals with sleep apnea remain undiagnosed and untreated.

      Regarding the study, Edith Mensah-Osman, M.D., Ph.D., MBA, president/CEO and director of medical research at EENA Comprehensive Neurology & Sleep Center, Boynton Beach, Florida claimed, “The combination of the three identified biomarkers performed as well for asymptomatic patients as it did for symptomatic patients.”
