CPAP Titration Study - Testing

During a CPAP titration study, members of the sleep team will calibrate your CPAP. The goal is to find the right amount of air pressure to prevent your upper airway from becoming blocked. This eliminates breathing pauses in your sleep.

When you show up for the study in the early evening, you will be fitted with a nasal mask that is connected by a tube to a small electric unit. The fitting process is an important first step in the CPAP titration. Be sure to tell the technologist if the mask is uncomfortable or if there are air leaks around the edges of the mask. The electric unit has a fan that blows air through the tube, into your mask. When you wear the mask, the air will gently blow into the back of your throat. 

You will have some time to make yourself at home. There will not be any other patients in your room. You will have a bathroom available to use, and you may have a television that you can watch.

When you are ready to go to sleep, tell the sleep technologist. The technologist will attach sensors to your body to monitor your sleep in just the same way as in the in-lab sleep study. These sensors measure your brain waves, heart rate, breathing, oxygen levels and leg and arm movements. The wires are long enough to let you move around and turn over in bed. You will be asked to move your eyes, clench your teeth and move your legs. This will make sure that the sensors are working.

At certain intervals throughout the night, the technologist will remotely change the air pressure you receive through your mask. Pressure starts at a very low level and gradually increases. If problems are detected, the technologist may come into the bedroom to adjust or replace the CPAP mask. Tell the technologist if you are experiencing any discomfort with the CPAP treatment.

In the morning the technologist will test and then remove the sensors. The CPAP titration study is complete once you are awake and the sensors have been removed. You are free to leave and return to your normal activities.
