Summary

Obstructive sleep apnea (OSA) is a highly prevalent disorder that has major consequences for cardiovascular health, neurocognitive function, risk of traffic accidents, daytime sleepiness, and quality of life. For years, a "classic" model of OSA has been used to describe the disorder, which fails to capture it's complexity. Recently, a model for OSA called drive-dependent OSA was discovered be more prevalent in the OSA population. This drive-dependent OSA is due to ventilation instability that occurs during respiratory events however these individuals have spontaneous increases in drive during respiratory events that stabilize their airway (i.e., via improving upper airway muscle activity) and reduce the risk of respiratory events in people with OSA. Therefore, by stabilizing the ventilatory drive, OSA should be treatable. Acetazolamide is a pharmacological ventilatory stimulant and has been previously shown to reduce OSA severity. As such in this study, the goal is to demonstrate acetazolamide improves OSA severity in 'drive-dependent' OSA people by improving drive-related pharyngeal obstructions compared to the 'classic' OSA people.
