A sleep study is a test to see what happens to your body when it is asleep. When we are asleep, we are not usually aware of what is happening with our basic functions. For example our breathing can become laboured, we can snore or make funny movements. This page from Great Ormond Street Hospital (GOSH) explains what to expect when your child arrives to have a sleep study.
Why does my child need to have a sleep study?
What do we need to take for the sleep study?
- Your child’s ventilator (for example, CPAP or BiPAP) if this is used by your child while at home. Remember to include all equipment (including the machine, masks, tubing and so on) so that we can check and service it during your stay.
- Your appointment letter and associated paperwork.
- Food for your stay – we cannot provide any meals during your stay, so we advise you to have your evening meal before you come to the hospital. The hospital canteen opens at 8am and there are also plenty of local cafes where you can have breakfast.
- A small kitchen is available on the Sleep Unit with water fountain, tea and coffee facilities, microwave and fridge.
- Anything else that your child usually sleeps with, such as a soft toy, special pillows, duvets or blankets.
- Any medication your child usually needs.
What will happen?
- A soft probe is wrapped around your child’s toe to monitor their oxygen levels while asleep.
- Two sticky ECG pads are placed on your child’s chest to measure their heart rate.
- Two stretchy bands are put around your child’s chest to record breathing movements.
- A small position sensor is also placed on the chest to record in which position your child is sleeping.
- A small tube will be placed on the edge of the nostrils to monitor breathing rates.
- A small sensor will be stuck either on the thigh or below the collarbone to monitor carbon dioxide levels.
- Video and audio of your child’s sleep will also be recorded
