Sleep Studies

CHOC Mission Sleep CenterCHOC Mission Sleep CenterBaby Sleep Study

Your child’s doctor may request a sleep study to help diagnose a sleep disorder, or a 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. Our technologists are friendly, calming and experienced with children. They will do everything possible to make sure your child is comfortable during the study. The results of your child’s study will be scored by a technologist, and then interpreted by a physician. They will also be shared with your child’s referring doctor. CHOC specialists such as pulmonologistsneurologists, otolaryngologists (ENT) and psychologists may also be involved in your child’s care.

We ask that one parent or guardian stay with the child during the study. To minimize distractions for our young patients who are in a new environment, siblings are not allowed. 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.

Your child’s room will be kept cool, but blankets are available as needed. A technologist will place about 25 small metal discs, called electrodes, on your child’s head and body. The discs are not invasive and won’t cause any pain. They are attached to wires that record and transmit data to the control room. These wires are long and flexible, and we make every effort to keep your child comfortable while they wear them. A sensor will be attached to one finger, and small sensors will be placed under the child’s nostrils. Small elastic belts will be placed around your child’s chest and abdomen. None of this equipment should cause pain or extreme discomfort. While we understand that children may not be able to tolerate all of the equipment throughout the night, our technologists will do their best to keep it in place, in order to record the best data for your child’s study.

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.

We recommend that you pack an overnight bag with the following items:

• 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.

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.
If your child becomes ill, with symptoms such as fever, cough, congestion or vomiting, we ask that you please call us at 714-509-8651 to reschedule the study.

Our Mission Viejo location is staffed after 6:30 p.m. To reach us earlier in the day, please call the Orange location at 714-509-8651. If you need to call after 6:30 p.m., please call us at 949-365-2308.

You will be provided sleeping accommodations in the same room as your child. We ask that you continue to care for your child as you would at home, including feedings and diaper changes.
