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

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

When the test is completed, it will be evaluated by Dr. S. K. Nemani, MD, SC, a neurologist who is trained and board certified in sleep medicine. Results will be forwarded to the patient’s doctor for diagnosis and follow-up treatment.

Sleep Specialist

The Sleep Lab at Salem Township Hospital is under the medical direction of a Board Certified Sleep Specialist, Sajjan Nemani, MD.


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.

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.
