Sleep study is a test measuring important aspects of your sleep and therefore checking for sleep problems.
What happens with a home sleep study?
At the Birmingham sleep clinic, we will give you a portable sleep monitor to use at home, so you don’t have to spend the night in a sleep lab. This is generally carried out to diagnose breathing issues related to sleep such as sleep apnoea. The portable monitor is attached to your body and is configured to tart recording overnight. You are expected to carry on with your normal activities and go to bed at your usual sleep time.
The portable study allows us to diagnose breath holding during sleep, arousals from sleep which you may not be aware of and leg movements during sleep which can fragment your sleep.
For some sleep studies, we may organise an overnight study.
What happens during an overnight study?
Our technician attaches small, sticky patches called "electrodes" to your head, chest, and legs. He or she will also place a small flexible tube beneath your nose. An elastic sensory belt is wrapped around your chest and tummy too.
Each of these items has wires that connect to monitors which record your movement, brain activity, breathing etc.
We may organise an overnight sleep study if you...
- Have sudden jerking leg movements while you sleep, called "periodic limb movements."
- Feel very sleepy during the day and fall asleep all of a sudden, called "narcolepsy."
- Have trouble falling asleep or staying asleep over a long period of time, called "chronic insomnia."
- Do odd things while you sleep, such as walking
How should I prepare for a sleep study?
On the day of your sleep study, you should:
- Avoid alcohol
- Avoid stimulants such as coffee, tea, pops, and other drinks that have caffeine in the afternoon and evening(e.g.: Red bull)
- Take all of your regular medicines
