Preparing For Your Stay in Sleep Study Lab


Sleep Medicine at Phoenix Children's Hospital

One parent/guardian is allowed to stay the night with the child. Unfortunately, no siblings are permitted to attend the study with you. During the night of your stay, a sleep nurse will be available to answer any questions you or your child may have. The sleep nurse can also help ease any fear or anxiety your youngster may be experiencing.

Sleep Studies – Everything You Need to Know

Dr. Matthew Troester, Sleep Medicine

The study is painless and provides important medical information to your doctor. Phoenix Children’s Hospital works with a company called Sleep Med to help conduct the study.

What is it?

A sleep study is a computerized test that records important information about your child’s sleep. Depending on symptoms, an overnight sleep study may be necessary during which time oxygenation, sleep quality, the staging of sleep, leg movements and EKG rhythms are closely monitored and evaluated. A computer records your child’s:

  • Sleep Patterns
  • Brain Waves
  • Breathing
  • Body Movements

How does it work?

To set up for the test, the technologist will place sticky recording pads on your child’s head, face, legs and chest elastic belts across the chest and abdomen. After these sensors are in place, your child will lie in bed and go to sleep for the night.

One parent must stay with the child during the entire sleep study. A chair-bed is available in the same room for the parent to sleep on. No siblings are allowed in the Sleep Study Lab.

Tests may include:

  • Polysomnography (PSG)
  • Multiple Sleep Latency Testing (MSLT) – performed to obtain an objective measure of sleepiness
  • Maintence of Wakefulness Test (MWT) – used to determine effectiveness of wake promoting medications
  • CPAP Titration (this test is only done on a return visit if sleep apnea is found)

* Please note: These tests do not hurt. There are no needles or shots involved.

Preparing Your Child for the Sleep Study

Here are some tips and guidelines on what your child should and should not do prior to coming in to the Sleep Study Lab at Phoenix Children’s Hospital.


  1. Make sure your child has clean, dry hair.
  2. Give your child his/her regular medication unless your doctor has told you otherwise. Bring any medications your child is taking to the Sleep Study Lab. Eat dinner before you arrive. Food is not provided, but you can bring in snacks for bedtime and the morning. If your food or medication needs to be refrigerated, please bring a small cooler with you to the appointment. The Hospital does not provide a refrigerator for food or drink storage.
  3. Remove any fingernail polish from your child’s fingernails.
  4. Your child may come dressed in pajamas or other comfortable loose-fitting bed clothes or change after arrival.


  1. Do not allow your child to nap in the afternoon before the sleep study.
  2. Do not use hair sprays, oils, styling products, weaves or extensions.
  3. Many beverages and foods have caffeine in them.  Your child should not have any caffeinated foods or drinks for at least 12 hours prior to the sleep study.
  4. Do not dress children in one-piece outfits.
