Trial Outcomes & Findings for High Flow Nasal Cannula for Obstructive Sleep Apnea (NCT NCT03843372)

NCT ID: NCT03843372

Last Updated: 2020-12-17

Results Overview

The Apnea Hypopnea Index(AHI) is an index used to indicate the severity of sleep apnea. It is represented by the number of apnea and hypopnea events per hour of sleep. The AHI under one night transnasal high flow therapy will be compared with one night continuous positive airway pressure.
