What you can expect
When you arrive for your sleep study, our building will be locked. A phone is located on the right hand side of the door. Pick up the black handset up and hold the button down on the handset until security answers. Advise the operator that you are going to the third floor for an appointment. When you arrive at the third floor, ring the doorbell on the left side of the door. The technician will let you in (allow a few minutes for him/her to get to the door.) If either the phone or doorbell malfunctions, stay where you are. The technician will be watching for you and will come out to get you. You may also call for someone to come down.
The phone for The Sleep Lab at NIGHT is 703-845-0248.
When you arrive for your sleep study, the technician will take you to your room. You will then be asked to change into your nightclothes. Small sensors are placed on your head and body with tape and cream. The sensors are then plugged into a machine that will monitor your sleep. If you need to use the restroom, the sensors are unplugged. There will be a camera in your room to monitor your body movements. The technician will be outside your room the entire night. You will leave at approximately 6 a.m. the following morning.
What a sleep study shows
The sleep study monitors all stages of sleep. To do this, the following are recorded:
- Eye movements
- Heart rate, brain waves and muscle activity
- The level of oxygen in your blood
- Breathing and snoring
- Sudden leg or body movements
- If you have breathing problems, a CPAP (Continuous Positive Airway Pressure) machine may be used. CPAP is a device that can help you breathe and improve your sleep. It may be used during the second half of your study or on another night.
Getting your results
Your doctor will explain the results of your study at your follow up visit. It will take a week to ten days for your doctor to receive the results. If you have further questions please contact our office during the day at 703-933-3613.
