overnight sleep disorders study

arrival and departure

The OLBH Sleep Lab performs overnight sleep studies Sunday through Friday. The Sleep Lab's night-shift certified respiratory therapists are on duty from 8:00 p.m. to 8:00 a.m. The OLBH Sleep Lab is not equipped with a cafeteria or vending machines, therefore we recommend eating dinner prior to coming in for your overnight sleep study. Nightly appointment assignments are at either 8:30 p.m. or 9:00 p.m.

Individuals who rely on someone else for transportation should arrange for their ride to pick them up from the overnight sleep study by 7:00 a.m. 


Rooms are private, spacious and include a television.

what to bring

Please bring any prescribed medications with you, and take them on your regular schedule unless you were told previously to discontinue them. As always, if in doubt please discuss medications precautions with your physician.

You will need to bring and wear pajamas, preferably two-piece. You also should bring any personal hygiene items you will need such as:

  • shaving items

  • shampoo

  • toothbrush and toothpaste

  • combs, etc.

Please be aware that the OLBH Sleep Lab only has small "hotel size" towels, so you may want to bring your own. Many of our patients also find it enhances their sleep to bring their own pillow or blanket to use along with those provided.

Bringing snacks and drinks to your overnight sleep study at the OLBH Sleep Lab are allowed if they are caffeine and alcohol free. You may also want to bring a book or something else to occupy your time since you will not be going to bed immediately. We ask that you not drink any caffeine after 4:00 p.m. on the day of the study as this can affect your sleep architecture.

what to expect from the OLBH sleep lab professionals 

After arriving at the OLBH Sleep Lab for an overnight sleep study, you will be checked into a bedroom and asked to change into your pajamas. Make sure you do not have any braids, weaves, hairpieces, oil, or hairspray on or the sensors will not adhere to your scalp properly. We generally advise patients to shampoo and dry their hair before coming in. For men, if you don't mind shaving, it will keep the technicians from having to use glue in your beard or stubble.

The center's technicians will be placing small, dime-sized sensors on you to record your sleep, heart rate, and muscle tension. You also will have two elastic bands placed on your abdomen and chest to monitor respiratory movement; a sensor on your finger to monitor oxygen saturation; and a small sensor under your nose to monitor airflow. Even with the sensors on, most patients find that they have no problem getting to sleep. You are free to walk around with the sensors on, and once all are connected, you can go back to your room for some relaxation before going to sleep.

Bedtime is generally around 10:00 p.m., which allows you to adjust to your new surrounding before trying to sleep. Once the overnight study begins, the technicians will monitor your sleep from a centralized area of the center. The OLBH Sleep Lab's professionals are on the premises the entire night, and if you need to get up to go to the restroom or if you need anything you can just call out and they can hear you over the intercom in your room. If you have to get up in the morning at a specific time, please inform the center's professionals at the time of arrival.

We hope you enjoy your visit to the OLBH Sleep Lab. If you have any other questions about what to expect from an overnight sleep study at our facility, please call 606-833-3993.
