A good night's sleep is essential for good health. Unfortunately, sleep deprivation has reached epidemic proportions in America, and many do not get the sleep they need because of sleep disorders. Sleep disorders can lead to other health issues as well as problems with daily activities. Our sleep experts can partner with you to help you get a good night's sleep.

Common Symptoms of Sleep Disorders:

  • Sleepiness or drowsiness during that day that interviews with daily activities
  • Loud snoring
  • Sleep Apnea
  • Difficulty falling asleep or staying asleep

The Home Sleep Test (HST) involves coming to one of our locations to pick up your HST device and receive training on its use. This may be in the form of an online video that can be accessed from the comfort of your home or by one of our licensed sleep educators.  You will be using your HST device at home during sleep. During this recording, we will be collecting information on your breathing, effort of breathing, oxygen saturation, pulse rate, and snoring.

The HST is a good screening tool for breathing disorders during sleep. However, HSTs are not considered comprehensive sleep tests because they do not measure brain waves, so we are unable to measure your quality of sleep or to analyze the different stages of sleep. HSTs do not measure leg movements or detect leg movement disorders.  Further, HSTs are good for screening for sleep apnea, but often reveal potential central sleep apnea (CSA).  If CSA is seen on your test, you may be asked to come in for an in-lab study to confirm as it is treated in a different type of modality. Please talk to your physician or asked to be referred to a sleep specialist to see if a home study is right for you.  

If you've already received your HST device, watch our video to learn how to best optimize your experience.

Polysomnogram (sleep study)

This is a recording that includes measurements used to identify different sleep stages and classify various sleep problems. We offer Diagnostic Testing, Continuous Positive Airway Pressure Titration Testing and Multiple Sleep Latency Testing.

The testing process

The technician will attach electrodes (small metal discs) to the head and skin with adhesive. These electrodes monitor activities in the body during sleep (brain waves, muscle movements, heart rate and leg movements). Flexible elastic belts are placed around the chest and abdomen to measure the breathing process. A clip on the finger or earlobe measures the heart rate and the blood's oxygen level. A technician will monitor the sleep process through the night from the control room, separate from the bedroom. During the sleep cycle, the various body functions and measurements are recorded and monitored. A sleep specialist will review and interpret the record to help you and your health care professional understand your specific sleep problems.

Diagnostic testing

Centra offers overnight studies in the sleep lab. A patient stays overnight in a room – designed like a hotel – with monitors connected to their body to track sleep patterns. A certified polysomnographer runs the study, and a board-certified sleep physician reads the results to suggest treatment. The diagnostic study is the first-night study when the sleep process is measured. This test will provide the sleep specialist information required to recommend treatment and determine the need for additional testing.

CPAP titration polysomnography

This test is performed when the first study is positive for Obstructive Sleep Apnea. The study involves fitting for a mask that is adjusted to fit comfortably over the nose. The mask is attached to a positive airway pressure device that treats breathing problems during sleep. This testing measures the sleep process while using Continuous Positive Airway Pressure Therapy. The record will provide the sleep specialist information needed to recommend the appropriate pressure to treat the sleep apnea.

Split Night Testing

The Sleep Disorders Center offers Split Night Testing. Many insurance companies require that a split night study be ordered, and for those patients who meet specified criteria, treatment can and should be attempted. This would allow having the patient diagnosed and treated all in the same night. It is important to understand that even if the patient is not split, they may still have sleep apnea and likely need treatment. It just means that the patient did not meet the specified treatment criteria in the allotted time available.

Home Sleep Testing (HST)

The Sleep Disorders Center also offers convenient home sleep studies. After being referred to the Sleep Center by a physician, patients can pick up a home study and are given a short tutorial on setting the simple system up. The next day, the patient returns the equipment, which records sleep patterns. The Sleep Center also provides a 24-hour number for patients to call with questions about setting up the home study equipment. The home study offers another alternative for patients to learn about their sleep patterns and seek additional treatment. Not all patients qualify for HST. The patient must be at least 18 years of age and have limited other medical conditions. Some of those may require the patient to spend the night in the lab for further testing.

Multiple Sleep Latency Testing (MSLT)

Nap Study. If indicated by the sleep study, a daytime study is performed. This testing is done from 8 a.m. through 3 p.m. A series of scheduled naps are taken during the day. The sleep patterns are recorded and monitored with the same equipment used with Polysomnography. The amount and type of sleep you get during these naps can help the sleep specialist understand your complaints and make treatment decisions.

Positive Airway Pressure Nap (PAPNAP)

Centra's Sleep Disorders Center offers several programs to help patients struggling with sleepless nights and apnea. The Center recently began providing PAPNAPs, daytime sleep studies designed to make patients more comfortable using continuous positive airway pressure – or CPAP – machines at home.

People battling sleep disorders often complain about uncomfortable masks or pressures too high and eventually quit using their PAP device. Many insurance companies require patients to be compliant with PAP machines for 90 days or return the equipment.

With a PAPNAP daytime study, technicians work with patients to adjust air pressure, find comfortable masks, and troubleshoot equipment problems. Patients must have a physician's referral for a PAPNAP, which typically lasts two to four hours at the Sleep Disorders Center at Centra Virginia Baptist Hospital.

Preparing for your study

Your referring physician will give you a Health History Questionnaire to be filled out in their office.  They will send that along with the needed information to order your sleep study.  One of our staff will contact you with your appointment date and information you will need regarding that study. 

If your sleep study is normal; we'll send a report to the referring physician with the findings of the study, and the sleep physician's interpretation of the polysomnogram.

If your sleep study is positive for sleep apnea, we'll send a report to the referring physician with the findings of the study, and the sleep physician's interpretation of the polysomnogram as well as a recommendation for further testing.

Sleep apnea

When you sleep, your body's muscles relax more than in waking hours. In some, this relaxation interferes with breathing because the airway in the back of the throat becomes too narrow. Sleep then becomes a time of increased health risk. 

Common causes of sleep apnea

A smaller than normal jaw, overbite, large tongue, enlarged tonsils or tissue that blocks the airway are contributors to sleep apnea. Alcohol, sleeping pills and tranquilizers taken at bedtime can reduce muscle tone and contribute to the collapse of the throat. Obesity, intrinsic hypertension, a short thick neck, are all contributing factors to sleep apnea.

Symptoms of sleep apnea in adults

Adults with sleep apnea may snore very loud (they can be heard rooms away), have a pattern of snoring interrupted by pauses, then gasps (the sleeper's breathing stops and restarts), have trouble concentrating, forgetfulness, depression, loss of interest in sex, headaches or nausea upon awakening, fatigue and frequent nighttime urination.

Sleep process

Sleep is controlled and influenced by many parts of the brain. The stages of sleep include drowsiness, light sleep, deep sleep and dream sleep. The stage of sleep a person is in can be determined by measuring the different activity of the brain and body.

Sleep problems in children

Children with sleep problems may snore loudly, appear to have difficulty breathing during sleep, sleep restlessly, sweat heavily during sleep, have daytime hyperactivity (sleepy children become fussy and overactive), behavioral problems, be cranky, be difficult to awaken and complain of morning headaches.
