The CPAP titration study determines the proper settings for CPAP therapy. CPAP titration is delivered using a mask or small plastic inserts that fit in the nose. Several types and sizes of masks are available. During a CPAP titration study, the air pressure delivered through the mask or nasal inserts will be increased gradually until breathing and sleep become normal. The mask and settings determined in the laboratory will be used when home CPAP therapy begins.
What to Expect
The CPAP titration study is essentially the same as a polysomnogram with the addition of the CPAP therapy. The technician will escort you to a comfortable, private bedroom. The room is equipped with a television set with cable. You will be asked to change into sleeping clothes (shorts or sweat pants and a loose top are best). The technician will attach the sensors to your head and body, and at approximately 10:30 p.m. to 11:30 p.m., you will be asked to go to sleep and the CPAP titration study will begin.
What to do Prior to the CPAP Titration Study
- Avoid caffeine after noon on the day of the test. This includes colas and some other soft drinks, coffee, tea and chocolate. If you drink alcohol on a regular basis (every day or almost every day), please have your usual amount on the day of the test. If you drink infrequently, (once a week or less) please do not have alcohol on the day of the test.
- Wash hair with shampoo to remove all hair products and then dry hair. Some products can interfere with the electrode contact with your scalp.
- Remove nail polish from one index finger, either hand, to allow for the placement of an oxygen sensor.
- Try not to nap on the day of the CPAP titration study.
- Bring any medications that you usually take at bedtime or in the morning, unless you have specific instructions from your doctor not to do so. Also, bring a list of all the medications you have taken in the two weeks prior to the test.
- Bring anything that might make your night in the laboratory more comfortable (pillows, earplugs, masks or stuffed animals).
The sleep center supplies toiletries including shampoo, conditioner, toothbrush, toothpaste and lotion.
