What is a sleep screening (trolley) study?
A sleep screening (trolley) study is a simple test that helps identify any sleep problems that your child may have. In this study, we measure the level of oxygen and carbon dioxide in your child's bloodstream using sensors on your child's skin, while they sleep.
The results tell us if further testing (for example a full sleep study) or treatment is needed for your child, or the results may be used to change a treatment your child is already receiving. Your child's doctor will discuss with you what they think should happen after the study.
What happens when you arrive at the hospital?
When you arrive at the hospital, ask the staff at the Enquires Desk for directions to the Sleep Unit. Please make sure you arrive at the Unit before 7pm, so we can prepare your child for the study.
The receptionist in the Sleep Unit will book your child in. You'll have to fill out some paperwork and then the receptionist will show you to the David Read Sleep Unit.
It's important that you stay in the Hospital with your child while they're in for the screening (trolley) study, otherwise we can't complete the study.
When you arrive, the Sleep Unit staff will explain what will happen and show your child the equipment to be used so that they are not frightened. This is also a good opportunity for you to ask any questions you or your child may have about the study.
We will provide dinner for your child. If your child is bottle fed or has a special diet, please ring the Sleep Unit on 9845 1150 by 9am on the day of your study and we will place a special order for them from the kitchen. There is a fridge and microwave in the parent room that you can use if you bring food for yourself from home, or you can purchase dinner at the Hospital cafeteria which is open until 8pm (or 6.30pm on weekends and public holidays).
You and your child will each have a bed to sleep in overnight.
When your child goes to sleep, the Sleep Unit staff will gently put a sensor on your child's finger or toe to measure oxygen and a sensor onto the skin of their chest or stomach to measure carbon dioxide. The Sleep Unit staff will come into the room every hour to record the numbers on the machine. We try to do this quietly and gently to not disturb you or your child while you sleep.
We will monitor your child for at least 8 hours while they're sleeping. Around 5:30am or 6:00am, we'll gently wake your child and disconnect them from the sensors.
As we need to prepare the space for other patients, we do ask that you get up once we've removed the sensors. We will then take the equipment out of your room and look over the results. The doctor will also take blood from your child's arm in the morning. You are free to go home after this is done.
You need to make a follow-up appointment with your referring doctor or Sleep/Respiratory Doctor to discuss the results of the study.
