Frequently Asked Questions about CPAP Care, Treatment and Supplies

CPAP - Polysomnography with Titration

What does CPAP stand for?

CPAP stands for Continuous Positive Airway Pressure therapy. A CPAP study is a polysomnogram (sleep study) with CPAP titration and is the second part of most sleep studies. This portion of the sleep study is broken up into two nights. The first night is dedicated to diagnosis and the second night to therapy.

Why do I need a CPAP study?

You may need a CPAP study because your airway has a tendency to be blocked while you sleep. This may be caused by physical obstructions, central signaling problems, apneas, hypopneas, or other various causes.

Why do you have to “titrate” the CPAP?

Titration, by definition, is the determination of rank or concentration of something. Over the course of the night, a sleep technician will change the level of pressure on the CPAP until “arousals” (things that keep you awake) are eliminated and you begin to sleep soundly. Everyone is different and you will need to be titrated to your own unique level of air pressure.

Why do I have to wear a mask?

The mask allows a sleep technician to titrate you and deliver the air pressure necessary for keeping your airway open. Masks come in all shapes and sizes. The three major categories of masks are: nasal pillows (smallest) nasal masks and full-face masks (largest). You will be fitted for a mask that is comfortable and fits you best.

Do I have to do anything differently from my first sleep study?

No. Your preparation for the second study will be the same as the first.
