What is a Sleep Study?

A sleep study is done at the hospital and requires an overnight stay in our comfortable, specially designed-rooms.  

During your stay, you are monitored by using painless, skin-surface devices. Staff members track your brain waves, muscle movements, and eye movements. Your body’s oxygen saturation, heart rate, chest and abdominal efforts, body and leg movements, and airflow from your mouth and nose are also monitored.

When your test is completed, it will be evaluated by a physician who is trained and board-certified in sleep medicine.  

Results will be forwarded to your doctor for diagnosis and follow-up treatment. 

Home Sleep Testing (HST)

Available for patients whose insurance does not cover in-lab testing, or for patients who are not able to come to the Sleep Lab.

Types of Sleep Disorders


Caused by chronic tension, poor sleep habits, drugs, or sleep apnea, insomnia is a condition in which a person has difficulty falling asleep, wakes up during the night or earlier than planned. Although many people experience periodic insomnia throughout their lives, if it happens frequently it should be evaluated by a doctor.

Sleep Apnea

Frequently noticed by spouses, a sleep apnea sufferer may stop breathing for 30 seconds or longer while sleeping. Characterized by loud snoring, daytime sleepiness, waking with a headache, and needing to use the bathroom during the night, this condition can be life-threatening.
Sleep apnea significantly increases the risk of motor vehicle accidents, high blood pressure, stroke, heart attack, congestive heart failure, and depression.

Restless Leg or Unusual Muscle Movements

Patients who suffer from restless leg syndrome often battle numbness, tingling, or searing pain in their legs or calves. This discomfort causes them to move their legs or body frequently, thus the term “restless leg syndrome”. This constant movement causes disrupted sleep and daytime sleepiness.


Symptoms of this disorder include uncontrollable episodes of falling asleep during regular daytime activities, nightmares, or hallucinations when beginning to sleep, or a feeling of paralysis
upon waking.

Sleep-Wake Scheduling

In today’s 24/7 world, many people have to live with a disrupted sleep schedule. When the regular pattern of sleeping and waking is interrupted by shift work, jet lag, or other factors, some people have a difficult time finding a sleep-wake pattern that suits their need for getting enough rest.

If you have a Sleep Disorder

Be assured that you’re not alone. In a recent study, as many as 40% of Americans reported some symptoms of a sleep disorder. The first step is to talk with your doctor, who may schedule a sleep study at Salem Township Hospital. If you do indeed have a sleep disorder, there are a wide variety of treatments available to help you.

Don’t put it off . . . chronic sleep problems can be life-threatening.

Schedule a Sleep Study

Your doctor must refer you to Salem Township Hospital’s Sleep Diagnostics Lab before a sleep study can be scheduled.  

Once you have been referred, or if you have the Doctor’s order for the study, you may contact us at (618) 740-0947.  

When your study is scheduled, our staff will give you more information about what items to bring with you and what you can expect while participating in the study.

If you have any questions, please call Chris Jahn, Director of Cardiopulmonary Services at Salem Township Hospital, 618-740-1649.


Sleep apnea is a disorder that afflicts 12 million Americans. People with sleep apnea repeatedly stop breathing at night. This puts a strain on the entire body causing the oxygen level in the blood to drop and the carbon dioxide level to increase. Sleep apnea is closely linked with heart disease in even mild to moderate cases.

Obstructive Sleep Apnea

Obstructive Sleep Apnea (OSA) is the most common type of sleep apnea. In OSA, loose tissue in the airway collapses during sleep, obstructing the air passages. This also causes snoring.


  • Heart Disease
  • Hypertension
  • Stroke


  • Snoring
  • Fatigue
  • Obesity
  • Morning headaches
  • Large neck
  • Poor concentration


CPAP (Continuous Positive Airway Pressure) is the most common treatment for sleep apnea.  The CPAP machine blows air through tubing and a mask which keeps the airway open.  Patients receiving CPAP therapy often report a drastic reduction of symptoms after using the machine.

Women and Sleep | Journal of Sleep Medicine

Admit it. You yawn. A lot. You don't wake up until you've had your coffee in the morning, you need another jolt in the afternoon to keep you going, then fall asleep watching TV at night. When you go to bed, you just lie there thinking of things you need to do. Think it's because of your busy lifestyle? It's more likely to be related to how well you sleep.
