FAQs About Sleep Studies
What to Expect: Sleep Study FAQs
If you’re considering or have been referred for a sleep study, you
likely have questions — and we’re here to provide answers.
Our goal at the LVMC Sleep Disorder Center is to make the process as clear
and comfortable as possible.
What does a sleep study monitor?
A sleep study, whether done at home or in our lab, tracks how your body
functions while you sleep.
We monitor:
-
Brain activity (to determine your sleep stages)
- Heart rate and rhythm
- Breathing patterns and pauses
- Oxygen levels in your blood
- Eye movement and muscle activity
- Snoring and airflow
- This information helps our board-certified sleep specialists diagnose conditions
like obstructive sleep apnea, insomnia, and more.
Will I actually be able to sleep in the lab?
Yes — most people sleep better than they expect. Our lab is designed
to feel more like a
private hotel room than a hospital.
You’ll find:
-
A
queen-size bed with a comfortable mattress and soft bedding
-
A
quiet, private space with a television
-
A trained technician monitoring your study from a nearby room
You’ll be able to follow your usual evening routine and bring items
that help you feel at home (like pajamas, a book, or a favorite pillow).
How do I prepare for my sleep study?
Preparation is easy!
Here’s what to do:
-
Avoid caffeine and alcohol the afternoon and evening before your study
-
Shower and avoid using lotions, oils, or hair products (they can interfere with sensors)
-
Bring comfortable sleepwear, any medications you usually take at night and toiletries
-
Arrive on time and plan for a full night’s rest — we’ll typically wake
you around 5–6 a.m. the next morning
- You’ll receive a detailed instruction sheet prior to your appointment.
What if I’ve already done a home sleep test (HST)?
If you’ve recently completed a home sleep test, great! That’s
often the
first step in diagnosing sleep apnea.
Depending on your results, your sleep specialist may:
- Use the data to create a treatment plan
-
Recommend an
in-lab study for a more detailed look
-
Evaluate whether advanced therapies like
CPAP or Inspire are appropriate
- Even if you've done a home test, the next steps can vary — and we’ll
walk you through them.
