Overnight Sleep Study: What to Expect
Sleep-related breathing disorders such as sleep apnea
- Sleep-related seizure disorders
- If a CPAP machine is recommended, (for use in cases of sleep apnea) the correct settings will be determined during the sleep study
Sensors are used to monitor your body while you sleep. The polysomnogram records:
- Brain activity
- Eye movements
- Heart rate
- Blood pressure
- Amount of oxygen in your blood
- How much air is moving through your nose while you breathe
- Chest movements, showing how much effort is expended when you breathe
What to bring
You will be shown your private bedroom and asked to put on your pajamas.
A technician will place surface electrodes on your body. These sensors record electrical signals generated by your brain and muscle activity. The recorded data helps your physician to understand what happens while you sleep.
Before the study begins, you will have time to relax and sleep. You may want to read a book or watch some TV.
Riverside technicians will monitor you from another room while you sleep. They will be able to react quickly if you have any questions or need any help during your stay.
The study should end around 5:30 to 6:00 the next morning.
Your physician will review the results of the test with you in a timely manner.
