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 pulmonologists, neurologists, 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.
The CHOC Sleep Center has two locations that are designed for quiet and comfort, with technologists that are friendly, calming and experienced with children. In this video, learn what happens when your child has a sleep study at CHOC.
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.
