What causes sleep apnea?
During sleep the muscles at the back of the throat relax, in everybody.
In some people the muscles relax so much that the wall of the throat collapses.
As the person tries to breathe, no air can get in. Eventually the effort
of breathing wakes him up for a short time, and this may happen over and
over. This describes obstructive sleep apnea, or OSA. The person is not
aware of waking frequently to breathe, but even mild sleep apnea can cause
daytime sleepiness, poor memory and concentration, and depression.
How can I treat my snoring or sleep apnea?
Most people who snore should lose weight, stop smoking, and stop alcohol
intake. Losing weight, 10%-15% of body weight, usually improves a person's
sleep apnea very significantly. Continuous Positive Airway Pressure, or
CPAP, is the treatment we usually recommend for people with sleep apnea.
Surgery usually is done for people with sleep apnea, only after other
treatments have failed.
What is a polysomnogram?
A polysomnogram, or sleep study, is a continuous recording of selected
body functions during sleep. The test also records brain waves, eye movements,
and muscle tone, which together determine the sleep stages. Heart rate
and rhythm sleep movements, and snoring sounds are also monitored. For
possible sleep apnea, we record breathing and oxygen level. Additional
polysomnographic measurements can be made in people with other suspected
Who can I contact if I think I need a sleep study?
Your Primary Care physician can order a sleep study for you or refer you
to a physician who is a sleep specialist. Insurance authorization for

What sensors are applied during the recording?
Sensors are applied to the scalp and skin. Blood oxygen is monitored using
a cushioned clip that is kept on a finger throughout sleep. Respiration
is monitored by using a thin sensor placed between the nose and upper
lip. Breathing effort is recorded using belts placed around the chest
Will the recording be painful?
No. If you have sensitive skin, you may notice mild skin irritation from
electrode paste or adhesive. No needles are used during a sleep study.
Who will be present in the laboratory while I am sleeping?
A trained sleep technologist will monitor your sleep from an adjacent
control room, while you sleep in a private room.
What happens to my sleep recording after the test is finished?

who is Board-certified in Sleep Medicine will review and interpret the
results. The results and any resulting diagnosis will be forwarded to
