Sleep Study

Sleep Study: What to expect

A sleep study, also known as a Polysomnography, involves monitoring the sleep of your child to evaluate for various sleep disorders.

While there are a lot of wires involved, as well as a lot of sticky pads, the procedure is painless.

The setup for the sleep study includes:

  • EEG leads to monitor brain waves during sleep
  • Sensors on the nose to monitor airflow
  • ECG sticky pads to monitor the heart rhythm
  • Stretchy belts for breathing movements
  • Sticky pads for muscle tone
  • Oxygen and CO2 sensors
  • Video recording for parasomnias, seizures and safety

Getting to your Sleep Study

  • A sleep study is an overnight test. A caregiver will have to stay with the patient for the duration of the study.
  • Please arrive at the lobby of Driscoll Children’s Hospital at 3533 S Alameda St, Corpus Christi at the time specified in your appointment (between 7:30 p.m. – 8:00 p.m.). This is known as the Emergency Room entrance. Please let the Welcome Center know that you are here for your sleep study. The sleep tech will then meet you and your child and escort you to our Sleep Center on the 8th floor.
  • Study usually ends in the early morning, around 5:30-6:00 a.m.
  • While COVID precautions remain in effect, a COVID test needs to be done prior to the study. When scheduling the sleep study, you will be guided as to when and where you can obtain COVID testing.
  • If you need to reschedule your sleep study, please call 361-694-4679 or 361-694-4447 as soon as you can.
  • If you do not show to your sleep study appointment without informing the Sleep Center, you will be required to return to the Sleep Center before another sleep study can be scheduled. 

How to prepare for a Sleep Study

  • Your child should wear comfortable, loose two-piece pajamas.
  • If your child has a particular pillow they always sleep on, consider bringing it with you.
  • Setup takes approximately one hour. The study will run until about 6:00 a.m. the next morning.
  • The caregiver is encouraged to bring a full set of sleepwear as well, as they will also spend the night.
  • Please bring diapers and all personal care items as needed.
  • Plan on having dinner prior to arrival, as we do not provide dinner. A small snack such as crackers may be arranged if needed.
  • For patients who require milk or formula at night, please make sure to bring it with you.
