Can a 'Turtle Shell' or neck zaps improve sleep apnea surgery?

This study aims to understand if a person's lung volume influences how their throat collapses during a key sleep apnea surgery evaluation. Researchers will recruit 200 adults with obstructive sleep apnea who are already scheduled for a standard pre-surgical throat exam under sedation. During the exam, participants will be assigned to one of two groups: one will wear a special 'turtle shell' ventilator on their chest, and the other will have electrodes placed on their neck. Both methods aim to gently change lung volume to see if it reduces throat collapse, which could help doctors better predict who will benefit from surgery.
