Oxicapnography sleep study

What is overnight oxicapnography?

This is an overnight recording of your child’s oxygen saturations, carbon dioxide levels and heart rate during sleep that is non-invasive.

What does the study involve?

  1. You will be welcomed to the Sleep House and shown to your bedroom.
  2. After settling in, a member of the physiology team will go through some paperwork with you.
  3. Once your child is ready for bed, staff will tape an oximetry sensor to your child’s toe, or finger, which measures oxygen saturation and heart rate.
  4. A warm probe will then be attached to either the chest or ear which measures carbon dioxide levels. After these have been attached, you and your child will be left to settle and go to sleep.
  5. Overnight, staff will monitor the signals via a video camera with your written consent. Staff may come in overnight to reattach sensors if signals are lost.

How long does it take?

It only lasts 1 night, and you and your child can go home first thing the next day.

Are there any risks?

These sensors are not painful, however some children and young people may find it upsetting to have these sensors attached. We will work closely with you and your child to successfully apply these sensors.

What happens afterwards?

When your child wakes up and the study has finished, the sleep staff will remove your child’s sensors. We will then discharge you home promptly. The latest you can leave the sleep house is 7.30am. Your child can then go about their day as normal.

When will I get the results?

The sleep physiology staff will pass the data onto the sleep and respiratory team.  The sleep and respiratory consultant will then look at the results and they will be discussed either at your next clinic appointment or the results will be sent to the referring doctor.

Information:

Results will not be available during your stay with us. It can take a few weeks to get the results.
