- Your heart rate
- Chest movements that show whether you're making an effort to breathe
What to expect
If your doctor recommends this test, you will need to visit one of our sleep centers or your doctor's office to pick up the equipment and receive instructions for how to use it.
The sleep recorder gathers important data as you sleep in your own bed. It receives information from sensors that are applied to strategic locations on your body:
- You may wear a belt around your chest and stomach to measure your breathing effort helping doctors determine if you have obstructive sleep apnea or central sleep apnea.
- Sensors near your mouth and nose may measure your airflow.
- Your blood oxygen level may be monitored because obstructive sleep apnea may cause decreased oxygen in your blood. It is measured using a pulse oximeter on your fingertip.
