Please do not nap (except if you have narcolepsy), drink alcohol or take recreational drugs for one week prior to, and during, your sleep study test. Do not consume caffeine (coffee, tea, cocoa and chocolate) after noon the day of your test. If your doctor wishes your study to be completed on your current medications, he/she will tell you this.

We need to study you during a typical night's sleep. If you normally have an alcoholic drink in the evening, continue with your usual practice. Please take all your usual medications.
If your sleep physician has identified you as being highly probable for obstructive sleep apnea (OSA) and you meet testing criteria, you may undergo a Level 3 study instead of an in-hospital sleep study. Level 3 studies involve you taking home a sleep monitor, wearing it for one night and then returning it back to the clinic for analysis. Level 3 studies are very effective in being able to quickly identify and quantify the degree of OSA present, which then allows for faster treatment.
Please report directly to the Admitting Department on the Main Floor. When the admission procedures are completed, you will be taken to the Sleep Laboratory. The technologist will meet you in your room and he/she will explain all the procedures that will be completed for your study. You will be asked some questions about your current health and your sleep.
You are encouraged to ask questions or express any concerns that you may have. The procedure is "non-invasive", meaning there will be no needles. We do require the use of gel to attach the electrodes that can easily be washed out of your hair after the test. It takes approximately one hour to prepare you for the study. The technologist will be available in the next room and you will be supervised at all times. You will have the ability to be disconnected during the study to use the restroom or walk around as needed.
The study will take place overnight and finish between 7:30 and 8:00 am. For patients with suspected sleep apnea, a doctor will discuss preliminary results with you in the morning, and may recommend treatment. Other patients are free to leave once the technologist has completed the study. You can buy breakfast in the hospital cafeteria. Patients staying for a daytime test will be served breakfast and lunch from the hospital kitchen.
If you require a second night's evaluation the technologist will inform you of when you should come in. After the first night, you do not need to return to the admitting department; come straight to the laboratory.
The MSLT (Multiple Sleep Latency Test) consists of four or five scheduled twenty-minute naps and runs from 8:30 am to 5:30 pm, depending on the results during the day. The earliest you will be discharged is 4:00 pm while the latest is 5:30 pm.
