TPAP for Comfort in OSA

"TPAP is a form of CPAP therapy where the therapy pressure is reduced from the beginning of inhalation through mid or later exhalation. The CPAP therapy pressure is only present at the end of the expiratory phase."

CPAP is a standard formal at home therapy for obstructive sleep apnea where a device attached via a facemask applies a constant pressure to a patient's lungs during sleep. It is the reference standard in this study.
