The Sleep Lab at Barnesville Hospital is a comprehensive, outpatient sleep program designed to diagnose and treat sleep disorders.

What is a Sleep Study?

A sleep study is a medical test performed during sleep. This test is used to evaluate and diagnose sleep disorders. Sleep studies are safe noninvasive procedures that provide valuable information to the ordering physician.

Testing is done on an outpatient basis. Patients are still required to register for sleep testing. Patients will have a private room with a television and bathroom. The night will begin with some paperwork and questionnaires to help with treatment. After the paperwork is completed, patients will be asked to change into their sleep attire. Before the sleep study can begin, the sleep technician will apply several monitors for recording sleep functions.

The setup includes electrodes that will be secured to the face and scalp with a conductive paste. This can be dissolved with water and will wash off easily in the morning. Two breathing sensors are taped to the area between the nose and upper lip to monitor breathing. These sensors do not block the airways. Three adhesive electrodes are attached to the upper chest and shoulder blade to monitor heart rate and rhythm. Two electrodes are taped to each leg to record all leg movements that occur through the night. A cloth belt will be placed around the chest and the abdomen to monitor breathing. These belts are not restrictive and easily fit over clothing. A probe is also placed on a finger to record the amount of oxygen in the blood. This process is painless and patients may watch television or read during the setup procedure.

Before the sleep study begins, the sleep technician will discuss information regarding common sleep disorders and treatments. One common treatment that may be ordered is Continuous Positive Airway Pressure (CPAP) depending on diagnosis. If needed, the sleep technician will introduce this equipment.

The sleep study will begin around 10:00 or 11:00 p.m. and will end anywhere between 5:00 and 7:00 a.m. The room is monitored with a video camera and a telecom to allow communication between the patient and the technician.

Once the sleep study ends, the tech will disconnect all the wires. The results of your sleep study will be given to one of the board certified sleep physicians for interpretation. The results will be available during your follow up visit with your referring physician.



What is Obstructive Sleep Apnea?

  • Obstructive Sleep Apnea is when a person stops breathing repeatedly during sleep

  • Breathing stops because the airway collapses and prevents air from getting into the lungs

  • Sleep patterns are disrupted, resulting in excessive sleepiness or fatigue during the day


What causes the airways to collapse during sleep?

  • Extra tissue in the back of the airway such as large tonsils

  • Decrease in the tone of muscles holding the airway open

  • The tongue falling back and closing off the airway


How many people have Obstructive Sleep Apnea?

  • 4 in 100 middle-aged men and 2 in 100 middle-aged women have Obstructive Sleep Apnea

  • Most OSA sufferers remain undiagnosed and untreated

  • Obstructive Sleep Apnea is as common as adult asthma


What happens if Obstructive Sleep Apnea is not treated?

Possible increased risk for:

  • High blood pressure

  • Heart disease and heart attack

  • Stroke

  • Fatigue-related motor vehicle and work accidents

  • Decreased quality of life

  • Diabetes

  • Obesity


What are the signs and symptoms of obstructive sleep apnea?

If you or someone you know snores regularly and has one or more of the following symptoms, it may be Obstructive Sleep Apnea:

  • Snoring, interrupted by pauses in breathing

  • Gasping or choking during sleep

  • Restless sleep

  • Excessive sleepiness or fatigue during the day

  • Large neck size (>17″ in men, >16″ in women)

  • Crowded airway

  • Morning headache

  • Sexual dysfunction

  • Frequent urination at night

  • Poor judgement or concentration

  • Irritability

  • Memory loss

  • High blood pressure

  • Depression

  • Obesity


What should you do if you suspect you may have Obstructive Sleep Apnea?

  • Consult your physician and have a sleep study done. A sleep study can provide your doctor with information about how you sleep and breathe.

  • This information will help the doctor to determine your diagnosis and treatment options.


What is the treatment for Obstructive Sleep Apnea?

  • A CPAP (Continuous Positive Airway Pressure), pronounced “see pap”

  • Other treatments should include weight loss if needed, exercise, and avoidance of alcohol, sedatives, and hypnotics


How does CPAP therapy work?

CPAP treats Obstructive Sleep Apnea by providing a gentle flow of positive-pressure air through a mask to splint the airway open during sleep.

  • Breathing becomes regular

  • Snoring stops

  • Restful sleep is restored
