A sleep study, also called a polysomnogram, is a way to monitor someone’s muscles, brain and breathing while they sleep. Your child’s doctor may request a sleep study to help diagnose a sleep disorder or another condition related to sleep.
Our Sleep Centers are designed for quiet and comfort, with a highly trained team and the very latest in sleep monitoring equipment. The results of your child’s study will be scored by a technologist, interpreted by a physician and shared with your child’s referring doctor. CHOC specialists such as pulmonologists, neurologists, otolaryngologists (ENT) and psychologists may also be involved in your child’s care.
A sleep study is usually done on an outpatient basis. In addition to an overnight sleep study, we may also perform a multiple sleep latency test, which is conducted the following day. Children under the age of 1 may only have a daytime nap study, which lasts on average four hours.
The technologist will always be in the room next to yours. He or she will watch your child’s every breath, movement and brainwave using video monitoring and state-of-the-art equipment including:
• EEG, to monitor brain activity. Our EEG technology is compatible with long-term monitoring equipment, in case a more comprehensive EEG is needed.
• EKG, to monitor heart activity
• EOG, to monitor eye movement
• EMG, to monitor muscle activity
• Thermistor, to monitor airflow
• Pulse oximetry, to monitor oxygen levels
• Lightweight belts with sensors, to monitor respiratory effort
If a technologist identifies an issue with a child, they will immediately provide assistance if needed. If a serious issue occurs, both Sleep Center locations are located within our main hospitals and have access to all other support services, including intensive care and respiratory services.

Preparing for a Sleep Study
Children who are undergoing an overnight sleep study will be at the Sleep Disorder Center for about 10 hours, starting in the evening and ending the following morning. Children who are also having daytime testing will stay for an additional 10 hours.
• An adequate amount of diapers and formula for 10 hours, if needed.
• If your child uses a CPAP or BIPAP at home, please bring the mask and any medications if used.
• Bring all medications that your child will require during their stay at CHOC. • Healthy snacks. A cafeteria and vending machines are also available nearby.
• Sleepwear for you and your child. Your child’s sleepwear should not have enclosed feet or zippers.
• Your child’s regular pillow and favorite sleep toy or blanket, to help them feel at home.
• Books, homework, laptops/tablets or toys, to keep your child occupied and comfortable while awake. Free WiFi is available.
Prior to the study, avoid putting lotions, creams or oils on your child’s body and face. Your child’s hair should be clean and dry, with no hair products. Your child should avoid any sugar or caffeine (chocolate, coffee, tea or soda) prior to the study. Please have dinner with your child prior to arriving.
If your child requires any special equipment such as a feeding pump, suctioning, oxygen or a ventilator, please contact us at (714) 509-8651 to arrange this ahead of time. Please let us know if your child requires any mobility assistance (e.g. uses a wheelchair) when confirming the appointment.
If there is a change in your child’s insurance, please contact your doctor’s office and our office with current information, to prevent billing issues. Prior authorization from the insurance company may be required before the study takes place.
