Pediatric Sleep Studies

If your child has been having trouble sleeping, their pediatrician may have suggested that they participate in a pediatric sleep study. While it may feel a little overwhelming to hear that your child needs to be studied, a pediatric sleep study is a simple exam that allows medical professionals to monitor aspects of your child’s sleep to look for irregularities. 

In this article, we’ll explain what a pediatric sleep study is in more detail, provide you with tips on how to prepare your child for a sleep study, and what you should expect during one. We’ll also answer some common questions related to pediatric sleep studies. 

What Is a Pediatric Sleep Study?

A sleep study, also known as a polysomnography1, is a test that measures your eye and leg movements, blood oxygen level, heart rate, and breathing while you sleep. A doctor analyzes patterns in these measurements in order to diagnose a potential sleep disorder1. Sleep studies are either conducted in a lab or at home, each option accompanied by its own pros and cons.1

Pediatric sleep studies are essentially just sleep studies conducted for children rather than adults. During a pediatric sleep study2, a child’s brain waves, eye movements, heart rate, muscle tone, breathing movements, airflow, oxygen levels, and arm and leg movements are measured using sensors. 

A sleep technician monitors the child throughout the night to view patterns, and a doctor reviews all of this data after the pediatric sleep study has been completed.2 This way, the doctor can analyze if your child has a sleep disorder.  

In fact, a pediatric sleep study is the best way to diagnose pediatric obstructive sleep apnea, according to research3. Along with evaluating sleep apnea, a polysomnography can also identify4 neuromuscular disorders, chronic lung disease, tracheostomy decannulation, and periodic limb movement disorders.

When to Consult a Doctor About a Pediatric Sleep Study

If you’re worried about your child’s sleeping patterns5, it is wise to consult their pediatrician. Your child may be having trouble falling asleep or staying asleep, or you may be worried that they are snoring loudly or are too drowsy during the day.5 You may also have concerns about your child’s hyperactivity.5

If you have any of the above concerns, consulting a doctor is a great idea. A pediatrician can give you helpful next steps in learning more about your child’s sleep, which may include meeting with a sleep specialist.

How to Prepare Children for a Sleep Study

There are several ways you can prepare for a pediatric sleep study. Your child will likely be nervous beforehand, so leading up to the night of the study, you should prepare them accordingly. 

You may want to talk your child through exactly what is going to happen that night and why they’re participating in this study. Remind your child that you will be present6 the entire night and that nothing is going to hurt.

In addition to mentally preparing your child, there are some actions7 that you can take in order to make them more comfortable during the study. For instance, you should feed your child dinner before going to the sleep center.7 Additionally, don’t let your child nap the day of the study, as this may interfere with their ability to fall asleep at the sleep clinic.7 

When preparing ahead of time, you may also want to pack the following items to bring with you7:

  • Pajamas for you and your child
  • Change of clothes for your child and yourself for the morning 
  • A stuffed animal or comfort item that your child typically sleeps with
  • A pillow and blanket from home if that will make you both feel more comfortable (for you and your child)
  • A book for a bedtime story
  • Diapers and wipes if your child is not potty trained
  • Toiletries for you and your child
  • Any medications your child takes at bedtime

What to Expect During a Pediatric Sleep Study

As a parent, you and your child may be equally nervous when anticipating the upcoming sleep study. You should arrive at the sleep center on time with your child. A sleep technician will greet you and set you and your child up in a room.7 Next, they’ll apply sticky sensors to your child’s face, chest, and potentially other areas of their body.7

You will stay in the room with your child the entire night.6 Typically, one parent is allowed at a pediatric sleep study, and you should not bring other children with you.6 

If your child needs to use the restroom8 or get out of bed for another reason during the night, you will have a way to contact the sleep technician, who will come in the room and unhook your child from the sensors. 

Overall, this experience shouldn’t feel too far off from a typical night’s rest for your child. A 2011 study found that 68 percent of families surveyed reported that their child’s sleep pattern was normal during their pediatric sleep study.3 Additionally, these families didn’t feel like this study had a negative psychological impact on their child.3

Common Questions About Pediatric Sleep Studies

What Is the Youngest Age for a Polysomnography?

According to Yale Medicine, children as young as infants can partake in a polysomnography.5 A pediatric sleep study is non-invasive and uses sticky sensors, so you shouldn’t worry about causing discomfort for your child.

How Long Do Pediatric Sleep Studies Last?

Pediatric sleep studies, much like a typical polysomnography, will last an entire night9. Before your child’s sleep study, you’ll receive specific information from your clinic about the time that you need to arrive that night. When your child wakes up in the morning after the study, the sleep technician will remove the sensors, and the two of you will be free to leave the clinic.9

What Kind of Doctor Performs Pediatric Sleep Studies?

A pediatric sleep specialist10 will likely perform your child’s sleep study. However, a sleep technician will be the person who interacts with your child on the evening of the sleep test and is the person who will monitor the child throughout the night.

Additionally, other doctors may help your child with their problems related to sleep.10 Some of these doctors include neurologists, child development and behavioral specialists, and nutritionists.10

Final Thoughts

After learning more about pediatric sleep studies, you should feel more prepared about letting your child partake in a sleep test. It’s just like sleeping at home, but they’ll have a few sensors adhered to their skin. 

Before deciding to enroll your child in a sleep study, it is important to consult a medical professional. A pediatric sleep study is a fantastic way for a doctor to view a child’s sleep patterns and then provide them with interventions that can help them sleep far more easily.
