For most patients, a sleep study is a key diagnostic component of a sleep disorder evaluation. A sleep study, also called a polysomnogram (PSG), measures your brain wave activity, eye movements, muscle contractions, heart activity, breathing and blood oxygenation during sleep.
The information we collect during your study is reviewed and analyzed by our sleep specialists.
Yes, tours of the sleep testing laboratory are provided during the day. Please feel free to call us to schedule a daytime tour before your test. We will be happy to accommodate your visit. You are also welcome to take a tour during your scheduled appointment.
Once you have scheduled your sleep study, you will receive a welcome package either in the mail or via email containing forms you need to complete, along with directions and phone numbers to the facility. Be sure to bring the directions, phone number, completed forms and your health insurance card on the night of your study.
Apnix will bill your insurance if we receive complete and accurate insurance information. Because insurance plans and benefits vary greatly, specific questions about your policy and coverage -including co-pays and deductibles - should be directed to your insurance carrier or employer.
Please call our office between 9:00 a.m. and 5:00 p.m., Monday through Friday to discuss your special needs requirements. We will try to accommodate your needs and answer any questions you may have about the sleep study procedure. If you do not speak English you will need to bring someone to interpret for the entire night.
Your sleep testing slot has been specifically reserved for you. For the courtesy of all patients, if you must cancel, please call 48 hours before your appointment so we can offer your slot to another patient. Patients who cancel more than once must get a new referral from their doctor.
Your room is furnished with premium bedding, a private bath and cable TV. There are no phones in patient rooms; you may bring your cell phone.
Pack as you would for an overnight hospital stay. For the benefit of your privacy and comfort, please bring appropriate and comfortable 2-piece nightclothes (such as T-shirts and shorts or pajama top and bottoms). Other patients and staff members will be in the general testing area. Review the recommended checklist below to ensure that you have everything you might need.
Here Is Our Recommended Check List:
Please take your medications as usual and bring them to the center, if necessary. Upon arrival at the sleep lab, the technologist will be able to tell you your approximate bedtime so that you may take nighttime medications accordingly. Our staff will not be able to dispense any medication to you.
We also recommend that you discuss with your physician whether your medications will affect the sleep study results.
If you wear nail polish we might have to remove it from at least one finger to obtain a good signal from the oxygen sensor.
Please eat dinner before arrival. You may bring a snack if you wish. Dinner will not be provided at our Bellaire location, but is provided at our satellite locations which are within hotels.
Avoid caffeine (coffee, colas, chocolates, etc.) after 12:00 noon on the day of the study.
You may find that a shower before arriving at the sleep center will make you feel more relaxed. Please remove braids, hair weaves, and hair accessories (clips, rubber bands, etc.). Wash and dry your hair and do not apply any sprays, oils, gels, or make-up.
Please contact the sleep lab directly (please see "Directions and Arrival Instructions" for contact information) and let us know of your approximate time of arrival.
The study usually begins in the late evening and ends about 6:00 AM. Once you arrive at the center, a sleep technologist will welcome you and show you to your private bedroom. The technologist will ask you to fill out some forms and answer any questions you may have.
After you change into your sleepwear, the sleep technologist will place a number of non-painful sensors (also called electrodes) on your head, chest area and legs. The areas where the sensors will be attached are cleaned and the electrodes are attached with special gels and paste. (The gels and paste are harmless, however, if you have sensitive skin, please alert your sleep technologist prior to attaching the electrodes.) Elastic belts with sensors will be placed around your chest and abdomen. Airflow sensors will be placed under your nose and a finger clip will be applied to monitor your oxygen levels. All of the sensors will be connected to a small portable box that transmits signals to the sleep monitoring and recording equipment that is in a nearby control room.
You may find it a bit strange at first, but most people do not find it uncomfortable or an obstacle to falling asleep. We will make every effort to ensure that you are as comfortable as possible. If a problem arises, your sleep technologist will make adjustments. The bedroom has an open intercom that will enable you to communicate with your technologist at any time.
If you need to use the bathroom during the night, you can call your sleep technologist on the intercom for assistance. They will temporarily disconnect you from the sleep monitoring equipment.
The lab is a busy place and there will be other patients being monitored during the same evening. The sleep technologists remain awake in the control room throughout the night analyzing the information being collected while you sleep.
For certain patients with Obstructive Sleep Apnea (OSA), the sleep study may include the beginning of a treatment called CPAP (Continuous Positive Airway Pressure). After you are asleep for a period of time, the sleep technologist will be able to determine if you have evidence of OSA. If you have evidence of OSA, CPAP treatment may be started during the night. During your orientation, this will be thoroughly reviewed, and you will have plenty of time to ask questions.
If you are not already awake, you will be awakened between 5:30 AM and 6:15 AM.
The center does not provide breakfast, however most centers do have a kitchen with refrigerator and microwave, as well as a hot/cold spring water dispenser. You are welcome to use the kitchen or ask your sleep technologist for assistance.
You should plan to add an additional 30 minutes to your usual morning preparation time to allow us to remove the electrodes. You may take a shower to wash your hair to remove the gels and paste used to attach the electrodes. If you have long or thick hair, it may take longer to remove the paste. If you need to be somewhere at a certain time, please let us know when you arrive in the center so we can accommodate your request. If you have arranged for a ride, they will need to pick you up by 7:00 AM.
Your doctor may have ordered an additional test called a Multiple Sleep Latency Test (MSLT) or a Maintenance of Wakefulness Test (MWT) as part of your overall evaluation. This means that you will need to stay at the center for most of the following day for a series of brief naps. The naps are scheduled throughout the day. Please bring reading materials, puzzles or other entertainment items that will help you pass the time. Please bring your lunch and non-caffeinated beverage, or bring money to order lunch out. If you have been scheduled for one of these tests, additional information will be provided in your package.
A large amount of information is collected during your sleep study. A sleep specialist will analyze this information and a formal report with recommendations will be sent to your doctor. On the night of the study, the sleep technologists cannot provide you with any information about your testing results.
It usually takes up to five to seven business days for your doctor to receive your formal report. Please schedule a follow-up visit with your physician after that time to discuss the findings and recommendations for treatment. If you have seen one of our specialists, we will contact you as soon as possible to discuss treatment options.
