Frequently Asked Questions



How do I prepare for my sleep study?


Once you are referred to the South Valley Sleep Center, you may be required to see a sleep specialist prior to your sleep study. If a sleep study is deemed necessary, you will be asked to make an appointment to return and spend the night in one of our private, home-like bedrooms. On the day of your sleep study, you may take any medications that you usually take, unless otherwise directed by your physician.  Do not take any naps, as they may interfere with your study. Consume foods and drinks as you normally would, but avoid caffeinated foods and beverages and alcoholic beverages. Before you come in,  eat dinner, shower, and remove make-up, lotions, oils, and hairspray.


What should I bring with me?


You’ll  want to bring loose, comfortable clothes to sleep in, and although pillows are provided, you may prefer to bring your own. It is also very important that you bring your insurance card, and a list of all medications that you use daily (prescription and non-prescription, including nasal sprays, sinus medication, and/or nasal strips).  You may also bring a book or iPad or anything else that you'd like to do before you fall asleep.  Make sure it's is not something that will disturb other patients.  NOTE: If you’re already using CPAP,  you may bring your mask with you if you'd like.  


What happens when I arrive?


When you arrive at the sleep center, you will be shown to your room. The technician  will explain the procedure to you, have you complete a short pre-sleep questionnaire, and ask you to prepare for sleep in your normal manner. The technician will return to prepare you for your sleep study (sleep study prep takes approximately 15 minutes). We make every effort to honor your normal bedtime. During your study, your breathing, brainwaves, muscle activity and heart rhythms will be monitored using electrodes that will be attached to your head, chest, legs and various parts of your body. Try to relax and make yourself feel as comfortable as possible.


What happens the morning after?


Prior to leaving, you will be asked to complete a morning after questionnaire regarding your experience during the night. On occasion a patient may be required to stay the following day after their overnight sleep study for additional testing.Please let the technologist know (upon arrival) if you have to leave at a certain time or call for a ride. You may leave after the removal of your equipment, provided that no additional daytime testing is needed.


Should I take my regular medications prior to the study?


Most of the sleep studies are done with you taking your usual medications at the usual times. You may ask the doctor who referred you for your sleep study if there are any special instructions.  


What about caffeine?


You should not consume caffeine day of your daytime nap study. If you regularly drink caffeine, you should reduce your caffeine consumption by one cup per day to avoid caffeine withdrawal headaches that can ruin your study. If you are coming in for an overnight sleep study, do not consume any caffeine after noontime on the day of your study.


May I go to the bathroom once all the sensors are hooked up and I am in bed?


Yes. If during the night you need to use the restroom, simply let the sleep techs know, and you can easily be untethered so you can walk to the bathroom.
