Titration Study

A young woman sleeps peacefully in bed. The bed has white sheets and there is a green plant in the background.

CPAP, Bi-level or ASV Tests

Titration studies are overnight sleep tests available at Trinity Health.

A Continuous Positive Airway Pressure (CPAP) machine is used to treat patients diagnosed with Sleep Apnea. During the titration study, you will be asked to wear a mask that goes over your nose and mouth during sleep. The mask is then connected to a machine, which provides a positive flow of air into the airway. The pressurized air acts as a splint that allows the airway to stay open and controls snoring and apnea.

Your machine needs to be carefully adjusted to provide the proper amount of pressurized air. You will be able to try a variety of masks and select the one that is most comfortable and best meets your needs.

The set up is the same as for the nocturnal polysomnogram, except instead of the airflow sensor under your nose you will be wearing the CPAP mask.
