What To Expect In A Sleep Study
1. When you come to the sleep lab, a technologist will greet you and describe the test to you.
2. That person will place tiny wires on your scalp, chin, and a couple on your legs and arms. Dont worry! Youll look a little strange, but youre not there for a beauty contest, and it doesnt hurt! These electrodes will sense brain activity, eye movements, and muscle activity, and allow the sleep team to see whether you have all stages of sleep, whether youre breathing as you should when youre asleep. If you wake up and need to go to the restroom, thats okay too.
3. Youll wake up in the morning and shower if you want to, and go to work or home, as you wish. Youd be amazed, but people really do sleep pretty much like they do at home. If you dont, we will find out why. Your sleep is assessed on the fly as its being recorded by the technologist who wired you up. Then its scored by an expert scoring technologist and any abnormalities are noted. Finally, its reviewed once more, before its looked at, for the forth time, by a sleep doctor.
4. A comprehensive report is generated, and all aspects of your history are taken into account, perhaps even imaging of your airway, before a report is generated, and the test results gone over with you.
How Do I Get The Results
Your doctor will discuss the results of the home sleep test with you. A positive result is a strong indication that you have OSA. In this case the doctor will develop a treatment plan for you. It is possible for a home sleep test to produce a false-positive result. About 15 percent of people without OSA are likely to receive a false-positive result. This is even more common in older adults who often have other medical problems or sleep disorders that affect sleep. About 30 percent of older adults are likely to receive a false-positive result.
A negative result may indicate that you do not have OSA. But home sleep tests can produce a negative result even when you have OSA. This is called a false negative result. About 10 percent of people with OSA are likely to receive a false-negative result. This can occur for a variety of reasons. One common cause is data loss. Critical data may be lost if the equipment malfunctions or is set up improperly.
If you get a negative result, then your doctor may schedule you for an overnight sleep study at a sleep disorders center. This study will record more information than the home sleep test. It also will be attended by a trained sleep technologist. He or she will monitor your equipment during the night. The overnight study at the sleep disorders center will show whether or not the home sleep test was accurate.
Statistics Of Sleep Apnea
Sleep apnea is a pervasive sleep disorder that affects a large part of the U.S. population. At present, there are 326 million people in the U.S. Of these 326 million:
- 10% suffer from mild OSA
- 3.5% suffer from moderate OSA
- 4% have severe OSA.
The problem with only reviewing diagnosed cases is that an alarming 75-80% of cases remained unidentified. 25% of individuals with moderate obstructive sleep apnea have neither subjective nor objective sleepiness.
Symptoms Of Sleep Apnea
It can be difficult to tell if you snore if you live alone or cant participate in a sleep study, so here are some other indicators that you may be experiencing sleep apnea:
- Waking up frequently during the night
- Waking up with a dry mouth or throat
- Waking up with a headache
- Feeling like you regularly have poor quality sleep
- Feeling excessively tired or sleepy during the day, even if you get a full nights sleep
Snoring Means You Have Sleep Apnea
Snoring and sleep apnea are linked at an alarming rate but its not a diagnosis, just a clue a what-if. In fact, one in three men and approximately one in five women who are habitual snorers, suffer from some degree of obstructive sleep apnea1, which negates the all-or-nothing myth that all snorers have sleep apnea.
It has also been linked to a number of other health conditions like type 2 diabetes, obesity, heart failure and hypertension2. So, regardless of what is specifically causing snoring for you, if you snore or if you suspect you snore consider it a sign that something may not be right.

What Is Cpap Compliance And Why Do Insurance Companies Require It
CPAP compliance is determined by how often your CPAP machine is used. Most insurance providers require a minimum CPAP use of 4 hours per night for 30 consecutive days within the first 3 months. This is to ensure that you are actually in need of a CPAP device otherwise, insurance wont cover the cost. Simply put, you must comply to qualify.
How Is Cpap Compliance Measured
Compliance data is collected two ways older CPAP machines use SD cards or cellular modems, while newer models connect to a SmartPhone via bluetooth. Healthcare providers will have the opportunity to access compliance data either way, but one is faster and more reliable. Where older models will need a cell signal, newer models send your data directly to The Cloud, providing you and your doctor with customized reports on your sleep health. Some even share tips and advice!
Todays models offer extensive reports when calculating your CPAP compliance. For example, the ResMedAirsense 10 Auto CPAP measures your Apnea-Hypopnea Index , continuous positive airway pressure, mask leak rate, and overall breathing pattern through myAir a free online support program and app. All of this information can tell your doctor if your CPAP treatment is working.
In fact, your own CPAP machine can sense minute changes in air pressure, indicating whether or not youre awake, or if your mask isnt being worn. Obviously, you want clear answers when theres the possibility youll stop breathing during the night, which is why the only surefire way to cheat CPAP compliance is to wear your CPAP mask as it was prescribed.

Ways Sleep Apnea Can Be Diagnosed Without A Sleep Study
Doctors have a few different ways to diagnose sleep apnea, one of which is through a sleep study. A sleep study involves staying overnight at a sleep center or lab that has equipment to monitor your breathing.
But sleep studies may be inconvenient for patients who feel uncomfortable spending nights away from home or dont have a lab nearby. Fortunately, there are other ways for doctors to diagnose you. A doctor might:
Oral Appliance Objective Compliance Tracking
In the United States, Braebon Medical Corps DentiTrac is the only objective oral appliance compliance sensor available. The microrecorder, whose US commercial launch was in 2015, is sealed within biocompatible epoxy, then further sealed within the appliance. It uploads data to the cloud either from the dental office or remotely. Richard Bonato, PhD, president and CEO of Braebon, says, CPAP devices have benefitted from compliance measurement for years, and the recent availability of DentiTrac as the first FDA-cleared technology for objective oral appliance compliance measurement levels the field with CPAP.
Some oral appliance manufacturers to announce the addition of DentiTrac as an option with their devices include ProSomnus Sleep Technologies, Airway Management Inc, and SomnoMed. According to Bonato, The DentiTrac may be embedded within oral appliances using traditional acrylic or thermoform technology or newer CAD/CAM designs such as those using nylon. We have had success using all designs. To not interfere with tongue space, Braebon recommends either the buccal sulcus or vestibule for microrecorder placement, though it has positioned DentiTrac palatally within removable orthodontic appliances without issue.
As technology continues to progress, more products to ensure reliable data are sure to debut.

How To Tell If You Have Sleep Apnea
Sleep apnea is a tricky conditionthe main symptoms often happen when you arent awake to notice them. Untreated sleep apnea can lead to excessive daytime sleepiness and is associated with long-term health complications, so its important to get an accurate diagnosis if you want to start sleeping easier.
Some patients only find out they have sleep apnea after a bed partner tells them about snoring or disrupted breathing at night, or after having an overnight sleep study done in a hospital or sleep center.
But how do you tell if you have sleep apnea if you live alone or if you dont want to participate in a sleep study? Lets discuss the different ways doctors diagnose this conditionand talk about how your dentist can help during treatment.
Why It Is Done
Sleep studies may be done if your sleep is not restful or if you are tired all day. These studies can help find sleep problems, such as:
- Problems staying awake, such as narcolepsy.
- Problems with nighttime behaviors. These include sleepwalking, night terrors, bed-wetting, and REM behavior disorders .
- Conditions such as periodic limb movement disorder. This is repeated muscle twitching of the feet, arms, or legs during sleep.
- Seizures that occur at night .
- Ongoing problems that have not responded to treatment.

First you need a full clinical evaluation by a licensed doctor. Your doctor will determine if you are a good candidate for a home sleep test.
Board-certified sleep specialists have expertise and the most experience at evaluating people for OSA. To meet with a board-certified sleep specialist, schedule an appointment at a sleep disorders center that is accredited by the American Academy of Sleep Medicine . The AASM sets strict standards for centers to maintain. This is to ensure that patients with sleep disorders get the highest-quality medical care. You can find an AASM-accredited center near you by going online to www.sleepcenters.org.?
If your evaluation shows that you are at risk for OSA, then your doctor will schedule you for either an overnight sleep study at a sleep disorders center or a home sleep test. If you are going to do a home sleep test, then you will receive the equipment and instructions that you need. A trained sleep technologist or other health-care professional should either apply the sensors to your body or show you how to self-apply the sensors at home. You should ask any questions you may have about how to operate the recording system. You also should find out when and how you need to return the equipment.
At your normal wake time, remove the sensors according to the instructions. Then return the recording system to your doctors office.
Home Sleep Test Devices
There are several variations of sleep test devices used to perform at-home sleep trials. They are portable devices usually named and classified by the type and number of sensors the tests use.
Type 3 Home Sleep Apnea Testing devices typically include the following:
- Respiratory Effort Sensor Belt: This belt wraps around your chest. It measures your respiratory effort throughout the night. The belt also secures the other components of the device.
- Nasal Cannula: The plastic tube loops over both ears and is inserted into your nostrils. The cannula measures your bodys airflow.
- Pulse Oximeter: The pulse oximeter sits on your index finger. The oximeter measures your bloods oxygen saturation levels. In many home sleep devices, the oximeter also measures your heart rate.
Other sleep test devices are ARES and WatchPAT. ARES devices are worn on the head like a headband. These measure airflow, oximetry, head position, and a limited electrical reading of the forehead. A WatchPAT is worn on the wrist, like a watch, and has a pulse oximeter you attach to your index finger. Unlike a Type 3 or ARES test, the WatchPAT doesnt measure airflow.
The appropriate home sleep test device depends on your sleep apnea symptoms and their severity. Your doctor can determine which device is appropriate for you.

How to fake sleep apnea. There was no normal sleep, and i was given a clean bill of health. I have read several threads on here in other forums about drivers being rejected, fired or other sanctions because their neck size is over 17 or their bmi is over 38 as they are candidates for sleep apnea. There are plenty of reasons why a cpap wont work for many people, and most of the doctors who prescribe them dont investigate those issues before prescrib.
What you are describing is not sleep apnea. The devices were manufactured between 2009 and april 26, 2021. Sleep apnea can lead to serious problems with your health.
Whod want to fake sleep apnea and try to fool the sleep study test a person wanting to scam an insurance company new home sleep test for patients with sleep apnea a young man wanted to know if he could fool a sleep study test into yielding a positive result for sleep apnea to gain some kind of insurance benefit of which i dont recall the details. Heres just an abbreviated list of some of the serious health risks associated with sleep apnea: If you hear any pauses in breathing, then audible exhales, thats a case of sleep apnea.
A sleep study is conducted if a patient snores loudly, gasps for air in the middle of the night, or experiences a sense of sleepiness during the day. I am not that overweight so i could ask for a lap band on just that basis. Recruiter sent me to concentra in bakersfield for my pre academy dot physical.

What Sleep Disorders Can Home Tests Detect
Currently, at-home sleep tests are designed to test for obstructive sleep apnea. These tests are recommended only for people with symptoms that indicate moderate to severe obstructive sleep apnea. Those with a history of cardiorespiratory diseases, stroke, insomnia, or hypoventilation should do their sleep study in a lab and not conduct an at-home sleep test.
Whod Want To Fake Sleep Apnea And Try To Fool The Sleep Study Test A Person Wanting To Scam An Insurance Company
A young man wanted to know if he could fool a sleep study test into yielding a positive result for sleep apnea to gain some kind of insurance benefit of which I dont recall the details. But I found his thread in a sleep apnea forum.
Ethics aside, CAN a person fake sleep apnea enough to fool any kind of test for it?
To my knowledge, not really, begins Joseph Krainin, MD, board certified in sleep medicine and neurology and founder of the online sleep apnea clinic Singular Sleep.
You can hold your breath and fake central sleep apnea but, unless you have a serious cardiopulmonary problem such as COPD or congestive heart failure, you likely wont be able to fake the typical oxygen desaturations that follow these breathing events so a good sleep doctor will pick up on this, continues Dr. Krainin.
What would you need to do to fake obstructive or central sleep apnea?
In order to fake sleep apnea, youd have to be able to be in bed throughout the night while remaining wide awake enough to repeatedly fake the condition.
If you let yourself fall asleep, you just botched your scam.
So first of all, youd have to succeed at fighting the urge to fall asleep which can be done if you prepare days ahead of time by switching your schedule to that of a night shift worker.
Years ago I got a third shift job and was asked to come in the night of the day I was hired. I said, I dont think so, but I can come in the next night.
