Breathing new life: can lung volume predict sleep apnea surgery success?

This study looks at how the amount of air in your lungs affects throat collapse during sleep in people with obstructive sleep apnea (OSA). Researchers will use a special camera to watch the throat while patients are sedated, and test two methods to change lung volume: a chest ventilator or nerve stimulation. The goal is to better predict who will benefit from surgery and possibly develop new treatments. About 200 adults with OSA who are already scheduled for this evaluation will take part.
