UChicago Medicine Sleep Disorder Center

[MUSIC PLAYING] The University of
Chicago has always been at the forefront of sleep. We have a very rich tradition
dating back decades. The main thing we
focus on is helping patients improve their sleep and
dealing with sleep disorders. One of the most common
reasons that patients end up coming to the sleep laboratory
at night as an outpatient is to get evaluated for
presence and severity of obstructive sleep apnea
or central sleep apnea. Typically, we ask
patients to come here after they have their
dinner, around 8:00 at night. Children naturally come a little
bit earlier with their parents. We don’t need eight
hours of sleeping like a baby to make a
diagnosis of a sleep disorder. For most sleep disorders,
we can make a diagnosis after even two,
three hours of sleep. It’s really and truly
a noninvasive test, where patients get hooked up
by a sleep technologist, who has a lot of
expertise doing this, and to kind of make the
patient feel comfortable about their surroundings. And these rooms are
designed in such a way that they look more like hotel
rooms, a small hotel room, as opposed to a typical hospital
room to make the patient feel more at home. At some point, we ask
to turn off the TV and turn off their mobiles
and turn off the light and try to fall asleep. We monitor sleep based
on brain activity. We monitor eye movements, so we
can pick up rapid eye movement sleep, which is a stage
of sleep during which we dream typically. And we have a little cannula,
like an oxygen cannula, but it’s not delivering
oxygen. It’s just sitting there measuring
flow of air the way we normally breathe. Naturally, we measure oxygen at
the finger and limb movements. And on top of that, one of
the things all sleep labs do is to have an infrared video
camera from which a sleep technologist is watching the
patient throughout the sleep. Naturally, the patient knows
that they’re being recorded. And they sign consent for that. And the purpose of
the recording is for us to verify body position
and any unusual movements during sleep. Once the sleep study is
over, typically around 6:00, 7:00 in the morning, the
patient is free to go. And then the next business
day in our sleep laboratory, the sleep medicine experts
review the sleep studies. And typically, our nurse
from the laboratory calls the patient
to briefly discuss what the sleep study
shows and what’s the next course of action.
