If your doctor thinks you might have central sleep apnea , you'll get a physical exam, give a medical history, and they'll likely recommend a sleep history. The next step probably will be an overnight sleep study. This happens in a sleep lab under the supervision of a trained technologist. During the test, the following body functions are monitored:
- Electrical activity of the brain
- Eye movements
- Muscle activity
- Heart rate
- Breathing patterns
- Air flow
- Blood oxygen levels
