What to Expect During a Sleep Study: A Complete Guide

Have you ever wondered what really happens during a sleep study? If your doctor has recommended one, you might feel a mix of curiosity and worry. At TriCity Lung & Sleep, we believe knowledge calms nerves — and better sleep begins with clarity.

In this guide, you’ll discover:

  • What a sleep study is
  • How to prepare for your sleep study
  • What happens while you sleep
  • How results help improve your health

Let’s pull back the covers on sleep testing.


Why Sleep Studies Matter

Sleep is vital for health, yet millions of Americans struggle with sleep disorders like sleep apnea. Left untreated, these issues can affect your energy, mood, and even your heart health.

A sleep study, also called a polysomnography, is the gold standard for diagnosing sleep disorders accurately. At TriCity Lung & Sleep, we offer in-lab sleep studies and convenient home sleep testing — because everyone deserves answers, and we work around the red tape to get them.


Preparing for Your Sleep Study

Whether at home or in our accredited sleep center, preparation is simple. Here’s how to get ready:

  • Stick to your routine: Keep your normal bedtime and daily habits.
  • Avoid caffeine or alcohol: These can disrupt sleep patterns.
  • Bring comfort items: Wear your favorite sleepwear and bring your pillow if you like.
  • Discuss medications: Tell your doctor about any prescriptions or supplements.

Relax — our team will explain every step when you arrive.


What Happens During an In-Lab Sleep Study

If you have an in-lab sleep study, here’s what to expect:

  1. Friendly check-in: You’ll be welcomed by a trained sleep technologist.
  2. Getting comfortable: You’ll change into pajamas and settle in a private, hotel-like room.
  3. Sensor placement: Small sensors are placed on your head and body to track brain waves, breathing, heart rate, and oxygen levels.
  4. Lights out: Once you’re cozy, you drift off to sleep naturally while the equipment does the work.
  5. Monitoring: A technologist watches discreetly to ensure the study runs smoothly and you stay safe.
  6. Morning wrap-up: You’ll wake up, have the sensors removed, and head home.

Many people say they sleep better than expected!


Home Sleep Testing — An Easy Alternative

For some patients, home sleep testing is the right fit. You’ll use a simple device while you sleep in your own bed. It records breathing and oxygen levels overnight. The next day, you return the equipment and we analyze the data.


Understanding Your Results

Our board-certified sleep physician, Dr. Saad Ahmad, reviews your sleep study data thoroughly. We look for:

  • Apnea events (pauses in breathing)
  • Oxygen dips
  • Sleep stages and disruptions

Then, we discuss the results with you in plain language — no jargon, no confusion. Together, we’ll choose a treatment plan that fits your life.
