Study Arms:
- Propofol (Type: ACTIVE_COMPARATOR): The healthy subject will be anesthetized with Propofol. Respiratory measurements will be taken while the subject is anesthetized to calculate the airway closing pressure. After recovery from anesthesia, airway diameter and duty cycle will also be measured. In addition to breathing air mixture, subject will be given carbon dioxide to achieve end tidal CO2 levels of 4 mm and 8 mm above baseline. All respiratory measurements will be repeated at each level above baseline. Assessment of swallow patterns during anesthesia and wakefulness, as well as under differential CO2 levels will be assessed offline after recovery from anesthesia.
- Sevoflurane (Type: ACTIVE_COMPARATOR): The healthy subject will be anesthetized with Sevoflurane. Respiratory measurements will be taken while the subject is anesthetized to calculate the airway closing pressure. After recovery from anesthesia, airway diameter and duty cycle will also be measured. In addition to breathing air mixture, subject will be given carbon dioxide to achieve end tidal CO2 levels of 4 mm and 8 mm above baseline. All respiratory measurements will be repeated at each level above baseline. Assessment of swallow patterns during anesthesia and wakefulness, as well as under differential CO2 levels will be assessed offline after recovery from anesthesia.

Based on this trial design, predict the completion outcome and termination type (if applicable).
