CPAP Titration Study - Overview

A CPAP titration study is a type of in-lab sleep study used to calibrate continuous positive airway pressure (CPAP) therapy. CPAP is a common treatment used to manage sleep-related breathing disorders including obstructive sleep apnea, central sleep apnea and hypoventilation and hypoxemia. Once you are diagnosed with one of these disorders, you may need a CPAP study before you can begin treatment.

In some cases, members of the sleep team may perform a CPAP titration study on the same night as an in-lab sleep study. This is known as a split-night sleep study. The CPAP titration occurs in the second half of the night. This is usually only offered if the sleep apnea is severe and the diagnosis is clear.

In more mild cases, the CPAP titration study may occur after a physician reviews the results of the in-lab sleep study. The physician will decide if and when you need to come in for a CPAP study.
