Most patients will have an initial consultation which will include a medical and surgical history. If you can, keep a Sleep Log for two weeks and bring it to your initial consultation. Some patients will also have pulmonary function tests and blood work.
After consultation with a sleep specialist, each patient is diagnosed. In some cases one visit is sufficient for a diagnosis to be made and a treatment plan formulated. In many cases the evaluation will require a sleep study. A sleep study or polysomnography (PSG) may be performed during a period of one or two nights. Rarely daytime studies will be required and may be suggested by your physician. Hospitalization is not required although the study is done in the hospital; overnight tests are completed by 8 A.M. It is usually not necessary to miss a day of work.
During a sleep study, the patient is monitored by painless, noninvasive technology. PSG records breathing, heart rate, brain waves, oxygen levels and eye and leg movement. After evaluation the appropriate therapy is determined. Treatment for a sleep disorder may include a prescription for a device to aid the patient's breathing while sleeping (called CPAP or BiPAP), medication, or light therapy as well as neuropsychiatric interventions, including biofeedback. If indicated, referral to or consultations with other specialists might be recommended to aid in diagnosis and therapy.
How to Make Your Overnight Study Comfortable
To ensure that your sleep study is technically accurate and that your overnight stay in the laboratory is a comfortable one, you are asked to prepare for your study in the following ways:
- Pack a small bag with all of the items you will need for an overnight stay away from home. These items include bed clothes and toiletries (shampoo, soap, toothbrush, toothpaste, etc.)
- Pack your prescription medication. The sleep lab does not stock or dispense any prescription or nonprescription medication
- Our technical staff consists of both men and women. There is only one technician on duty at a time. We cannot accommodate requests regarding the gender of your technician
- If you are in the habit of reading before going to sleep, bring a book or other reading material
- Unless otherwise instructed by a physician from the Center for Sleep Medicine, do not alter your sleep schedule during the week prior to your study. This helps to ensure that your night in the laboratory is representative of a typical night of sleep
- Please arrive at the laboratory on time. After 7:00 P.M., if you expect to be delayed for your study, please call 212-241-2989
- Avoid caffeinated food or beverages after noon on the day of the study
- Do not drink alcohol on the day of your study.
- It is advisable that your skin and hair are clean. This improves the ability to apply and remove electrodes. Use shampoo, but no oil or conditioners, on your hair, scalp, or skin
- If you develop a cold or respiratory infection this will affect reliability of study results. Please contact us immediately so that you can be rescheduled for a different night
- The test will conclude at your normal wake up time. Electrode paste will be applied to your skin and scalp. If you wish, you may shower in the morning before leaving the laboratory
- If the technologist observes a severe degree sleep apnea you may be advised not to drive home by yourself
